▼ Mestrado em Engenharia do Ambiente - Instituto Superior de Agronomia
The wine sector annually produces about seven million tons of residues and by-products such as grape marc, lees, seeds and the stalk. If these materials are mismanaged they can have a strong environmental impact. Moreover, some of these materials may have great potential through their physical and chemical characteristics, which may be used for others purposes. A strategy plan was presented, containing management alternatives, for each residue produced during one year campaign of wine production. To reach these goals we performed a survey for identification and characterization of all residues produced from the winery activity and a life cycle analysis of the product using software SimaPro to assist in choosing the best solutions to adopt. Through such strategies, implementation of specific legislation and voluntary attitudes as ISO's, it is possible to reduce the impact of human activity and lead enterprises to a more sustainable attitude towards the market at environmental, social and economic levels. This strategy may also allow reducing environmental impacts, by-products recovery, reduce landfill costs, optimize processes and to get some economic return

▼ U okviru disertacije ispitana je mogućnost eksploatacije nusproizvoda (nastalih tokom procesa hladnog presovanja ulja) kao izvora prirodnih fenolnih kiselina. Odabir je obuhvatio uzorke uljane tikve, crnog kima, lana i nara. Radi oslobađanja vezanih fenolnih kiselina i u cilju procene njihovog ukupnog sadržaja i distribucije (u čvrstim uzorcima), primenjena je alkalna hidroliza sa dodatkom L-askorbinske kiseline i EDTA. Dobijeni rezultati pokazuju da se sve analizirane pogače mogu se koristiti za dobijanje vrednih fenolnih kiselina, pri čemu raspodela fenolnih kiselina zavisi od vrste uljane pogače. Koncentracija slobodnih fenolnih kiselina se pokazala značajnom za pogaču uljane tikve, estarski vezanih za pogače nara i lana, a nerastvornih-vezanih za pogače crnog kima i nara. Od svih analiziranih uzoraka kora nara je sadržala najviše estarski vezanih fenolnih kiselina zahvaljujući veoma visokom sadržaju galne kiseline. Nakon određivanja fenolnih kiselina u nusproizvodima, analiza glavnih komponenti (PCA) je omogućila razdvajanje biljnih uzoraka u grupe prema poreklu i smanjila broj fenolnih kiselina neophodnih za njihovu karakterizaciju, što može imati potencijalnu primenu u skriningu fenolnih kiselina i određivanju kvaliteta/autentičnosti uljarica i njihovih nusproizvoda.
Within the thesis, the possibility of by-products (formed during the process of cold oil pressing) exploitation as a source of natural phenolic acids was examined. Selection of the samples included pumpkin, black cumin, flax and pomegranate. For the purpose of bonded phenolic acids release and for the total phenolic acids content and distribution (in the solid samples) assessment, the alkaline hydrolysis with the addition of L-ascorbic acid and EDTA was employed. The results show that all analyzed cakes can be used to obtain valuable phenolic acids, while the distribution of phenolic acids depends on the type of oil cakes. The concentration of free phenolic acids proved to be significant for a pumpkin oil cake, ester for pomegranate and flax oil cakes, and insoluble-bound for black cumin and pomegranate oil cakes. Of all analyzed samples, pomegranate hull contains the highest content of ester-linked phenolic acids, due to a very high content of gallic acid. After phenolic acids determination in the by-products, principal components analysis (PCA) allowed the separation of plant samples in groups according to origin and reduced the number of phenolic acids necessary for their characterization, which may have potential application in the screening of phenolic acids and determining the quality/authenticity oilseeds and their by-products.

▼ Depuis la fin du 20ème siècle, notre société a pris conscience que la protection de l’environnement et le développement durable sont nécessaires à notre épanouissement futur. Des directives ont contraint les pouvoirs publics, les collectivités, ainsi que les industriels à réagir notamment en s’impliquant dans la recherche. Les cimentiers sont aussi concernés. La fabrication du ciment nécessite énormément de matières premières.L’objectif principal de cette thèse est donc de valoriser les sous-produits industriels en matériaux cimentaires. Le contexte et la problématique des déchets sont abordés, ainsi que la possibilité de valorisation par les ciments. La méthodologie mise en place et son originalité sont expliqués. Dans un premier temps, le protocole de caractérisation des déchets minéraux a été développé et les résultats en laboratoire sont prometteurs pour le remplacement du calcaire et de l’argile dans le cru d’un ciment. Les cuissons en laboratoire ont permis d’obtenir un ciment comportant les 4 phases d’un Portland. La synthèse en plus grande quantité d’une formulation en laboratoire a mis en évidence de bonnes performances mécaniques sur mortiers au jeune âge. Dans un deuxième temps, les meilleures formulations ont été testées à l’échelle industrielle, dans le four de ARF. Le cru, malaxé par trémies agitatrices, a été une réussite. Enfin, l’immobilisation des polluants dans une matrice cimentaire des résidus de combustion, provenant des combustibles secondaires de ARF a permis de déclasser le déchet stabilisé/solidifié par réduction granulométrique du matériau avant tabilisation/solidification.
Since 20th century’s end, our society started to take conscience of environmental protection and sustainable development are required to our future blooming. Directives have obliged public authorities, communities, such as industry to be reacted particularly while being implied in research. The cement-manufacturers are also concerned. The process cement-manufacturer requires large quantities of raw materials. The main objective of the thesis is to value industrial by-products by cementitious materials. Context and problem of wastes were discussed, as well as the possibility of valorization such as the cements. The methodology set up for the thesis and its originality are explained. First, the protocol of characterization of mineral wastes was developed. The results in laboratory are promising for the replacement of limestone and clay in the cement’s raw meal and different formulations. The cookings in laboratory allowed obtaining a cement containing 4 phases of Portland. The synthesis in bigger quantity of a formulation in laboratory highlighted good mechanical performances on mortars at the young age. In a second stage, the best formulations were tested on an industrial scale in the ARF’s kiln. The raw meal, mixed by hoppers agitators, was a success. Finally, immobilization of pollutants in a cement matrix of the residues after combustion, resulting from secondary fuels of ARF, was studied to be able to downgrade the…

▼ Ce travail de thèse concerne l’utilisation des électrotechnologies pour une valorisation optimisée de la betterave à sucre conformément au concept de bioraffinerie. Les électro-technologies appliquées sont les champs électriques pulsés (CEP) et les décharges électriques de haute tension (DEHT). L’étude s’attache d’une part à l’optimisation d’un procédé alternatif pour l’extraction du sucre par pressage alcalin à froid assisté par CEP. D’autre part, elle propose des nouvelles voies pour la valorisation de deux coproduits de l’industrie betteravière qui sont les radicelles et la pulpe de betterave. Dans la première partie, le traitement électrique par CEP couplé au chaulage permet une meilleure désintégration du tissu betteravier. Il permet d’accélérer les cinétiques du pressage, d’améliorer le rendement ainsi que la qualité du jus et d’alléger la procédure de purification en aval de l’extraction. Une étude paramétrique d’optimisation a permis d’identifier le meilleur itinéraire d’application de ce nouveau procédé d’extraction. Les cossettes fraîches de betterave sont prétraitées par CEP à 600 V/cm pour 10 ms (Q = 2,7 Wh/kg). Les cossettes électroporées sont ensuite pressées à froid pour extraire 75 % du jus. Les cossettes pressées subissent un pressage alcalin avec 10 % du lait de chaux. Afin d’extraire le sucre résiduel dans le gâteau de pressage obtenu, deux étapes de pressage supplémentaires avec une étape intermédiaire d’hydratation sont nécessaires. Ce procédé optimisé permet de bien épuiser les cossettes en sucre (perte en sucre de 0,23 % et matière sèche de pulpes de 39 %) pendant une courte durée d’extraction (30 min) avec un faible soutirage (108 %) par rapport au procédé de diffusion. Il permet ainsi des économies significatives de matière et d’énergie surtout pour les étapes d’extraction du jus et de séchage de pulpes. Par rapport au procédé conventionnel, le gain énergétique s’élève à 91,96 × 106 kWh pour une usine traitant 10 000 t/j de betteraves pendant une campagne de 110 jours. De plus, le procédé proposé permet de simplifier la procédure de purification et de réduire de 50 à 60 % la quantité de chaux utilisée. Dans la deuxième partie de cette étude, deux procédés de transformation ont été proposés et optimisés à l’échelle laboratoire pour la valorisation des radicelles et de la pulpe de betterave à sucre. Les radicelles ont été utilisées pour produire du bioéthanol. Le jus brut de radicelles a été extrait par pressage à froid assisté par CEP. La production du bioéthanol a été achevée par fermentation alcoolique. Le prétraitement par CEP (450 V/cm, 10 ms) a permis d’accélérer la cinétique de pressage, d’augmenter le rendement en solutés (79,85 % vs. 16,8 %) et d’obtenir un jus plus concentré (10 % vs. 5,2 %). Le procédé optimisé permet de produire environ 41,75 L de bioéthanol par tonne de radicelles lorsque l’on applique un prétraitement par CEP contre seulement 8,2 L de bioéthanol sans prétraitement électrique confirmant ainsi le potentiel de ce nouveau schéma de valorisation. La pulpe de betterave…

Wine lees are a byproduct of the production of Port wine resulting from the deposition of waste in the
bottom of the containers during the maturation stage. Due to its richness in color and aroma, they
result in an excellent raw material for the creation of alternative products for the food industry.
The aim of this essay is to: (i) characterize the lees of two types of Port wine - Tawny and Vintage, in
fresh and freeze-dried form, with the objective of using it as a raw material base in the food industry,
(ii) develop and characterize a new food product by changing physical properties of fresh lees.
The characterization revealed that the lees of port wine have an intense color and flavor, low in protein
and fat, and high in polyphenols, with highest levels in the lees of Vintage Port. In rheological terms,
both fresh lees centrifuged showed a shearthinningbehavior. By adding xanthan gum to fresh lees a
microbiologically stable product was achieved, also with a shear-thinning behavior, which can be used
in several culinary preparations at high temperatures.
These results confirm the potential of port wine lees as a raw material base (lyophilized lee) and as an
innovative food additive (fresh lees)

▼ Two bauxite residue products, Alkaloam® and Red Lime™, generated from Alcoa of Australia’s Western Australia alumina refineries, have the potential to be re-used in a range of applications, in particular in agricultural land management as soil amendments for phosphorus retention and as an agricultural liming agent.Currently there are no regulatory frameworks or guidelines in Western Australia to promote and facilitate the re-use of industrial by-products. This is partly due to the lack of assessment protocols required to ensure that all regulatory standards have been met, with assurance that a by-product is safe and acceptable by the community as a suitable raw material for re-use. In addition, the Australian Standard Leaching Procedure (ASLP), the standard leach test adopted in Australia for environmental assessments, is significantly limited and not suitable for assessing leaching in industrial by-products, such as Alkaloam® and Red Lime™.The aim of this thesis was therefore to determine whether a more suitable leach test could be used as an alternative to ASLP for assessing industrial by-products and apply this leach test to Alkaloam® and Red Lime™ for investigating their leach behaviour when used as a soil amendment or liming agent.This thesis reported on relevant literature on the re-use of bauxite residue products, international leach test procedures and current assessment of industrial by-products for re-use.The European standard pH dependent leach test was compared to ASLP for assessing the leaching behaviour of Alkaloam® and Red Lime™ and for determining its suitability for assessing industrial by-products for re-use in different pH scenarios. This leach test was more superior to ASLP in that it provided more accurate and fundamental leaching information on Alkaloam® and Red Lime™ and was considered more suitable for assessing by-products for re-use, in particular materials that were highly alkaline and exhibited high buffering capacity.Method optimisation was conducted on the pH dependent leach test to improve leaching assessments on clay type soils and to allow nitrate leaching to be assessed in WA soils ameliorated with Alkaloam® and Red Lime.The main focus of this thesis was on characterising and assessing the pH dependent leaching behaviour of Alkaloam® and Red Lime™ and determining changes in leaching at different pH for a range of WA soils, when ameliorated with Alkaloam® and Red Lime™ at an application rate of 6.25g/kg (Alkaloam®) and 1.6g/kg (Red Lime™). A Bassendean soil and agricultural soils in the Peel Harvey catchment and Merredin and Newdegate region were assessed in this study. LeachXS™ geochemical modelling was applied to the pH dependent leach data to identify the processes controlling leaching of species in these scenarios as well as the speciation likely to be present in the liquid and solid phase during leaching.It is anticipated that this information will be a key input into the environmental assessment of Alkaloam® and Red Lime™ as an agricultural soil ameliorant and liming agent as…

▼ Objetivou-se avaliar a produção e composição do leite, consumo e digestibilidade aparente da matéria seca e dos nutrientes, eficiência de utilização dos compostos nitrogenados, produção e eficiência da síntese de proteína microbiana de vacas leiteiras alimentadas com diferentes proporções de substituição do farelo de soja pela levedura seca de cana-de-açúcar. Foram utilizadas 16 vacas holandesas, destas 8 eram primíparas e 8 multíparas, distribuídas em quatro quadrados latinos 4x4, organizados de acordo com os dias e ordem de lactação. Os tratamentos consistiram de uma dieta basal, onde o farelo de soja foi a principal fonte de proteína, e três dietas com os níveis de 33,3; 66,6 e 100% de substituição do farelo de soja pela levedura, com base na MS. O experimento teve duração total de 68 dias, subdividido em quatro períodos experimentais de 17 dias. Os níveis de substituição do farelo de soja pela levedura não influenciaram os consumos de MS, MO, EE, FDNi e NDT (P>0,05), porém os consumos de PB e FDNcp decresceram e o consumo de CNF (P<0,05) aumentou linearmente. Não houve efeito de tratamento sobre os coeficientes de digestibilidade da MS, MO, PB, CNF e no teor de NDT (P>0,05), porém o coeficiente de digestibilidade do EE decresceu linearmente com a inclusão de levedura nas dietas experimentais (P<0,05). A produção leite, produção de leite corrigida para 3,5% de gordura, teor de gordura, proteína bruta, lactose, sólidos totais e CCS não diferiram entre os tratamentos (P>0,05). Não foi verificado efeito dos tratamentos sobre a soma das excreções de alantoína na urina e no leite, ácido úrico, purinas totais, proteína microbiana e eficiência microbiana (P>0,05). Observou-se efeito linear decrescente para as concentrações de nitrogênio uréico no plasma e no leite e excreção diária de nitrogênio uréico no leite (P<0,05), porém não foi verificado diferença para excreção diária de compostos nitrogenados no leite, nitrogênio total e uréico na urina e balanço de nitrogênio (P>0,05). Conclui-se que a levedura seca de cana-de-açúcar pode substituir totalmente o farelo de soja na dieta de vacas leiteiras com média diária de produção de 25 kg de leite.

▼ Chlorine is always used in disinfection process of water treatment plant (WTP) in Kaohsiung, and the major of disinfection by-
products (DBPs) is THMs. Reaction of THMs producing were found in relation to lots of factors of water quality. Therefore we used SPSS to analysis the relation between water quality and THMs content for making prediction model of THMs formation in water distribution system in downtown Kaohsiung city. It is expected to estimate the concentration of THMs with a simple method, and to reduce THMs by controlling some items of water quality.
While the variance of TOC value is low, we found that concentration of THMs is related to temperature, pH, and residual chlorine by regression method. In these items, residual chlorine had the highest correlation. While the variance of TOC value is high, the correlation between the three items and THMs is weaker than the front one. From this finding, TOC is best one fitting factor in prediction of THMs. In this study, we found that R-square value of Multivariate regression prediction is higher than the value of Univariate regression prediction probably for THMs producing is a complex reaction, so formation model was hard using only one item of water quality.

Toxicity mechanism of anthropogenic water contaminants: drinking water disinfection by-products (haloacetic acids) and particle associated contaminants from sealcoats (polyaromatic hydrocarbons) in lake sediments.

▼ Drinking water disinfection was one of the major public health accomplishments of 20th century. Water disinfection helps in reducing waterborne diseases like typhoid fever, cholera, and hepatitis A. However, chemical water disinfection also produces unwanted toxic chemicals, known as water disinfection by-
products (DBPs). Most of the DBPs are cytotoxic, neurotoxic, genotoxic, mutagenic, carcinogenic and teratogenic but the toxicity mechanism is not completely understood. Therefore, the objectives of this dissertation were to i) understand the toxicity mechanisms and identify the molecular targets of all the regulated and non-regulated haloacetic acids (HAAs) water DBPs, ii) to differentiate among the toxicity mechanisms of mono-, di-, and triHAAs, iii) to evaluate the toxicity potential of chlorinated and chloraminated wastewater effluents, and iv) to evaluate the mutagenicity potential of the particle associated contaminants such as polyaromatic hydrocarbons (PAHs) associated with coal tar and soot, extracted from lake core sediments.
Studies based on the toxicity mechanism of HAAs water DBPs demonstrated that monoHAAs were the strongest inhibitors of glyceraldehyde-3-phosphate dehydrogenase (GAPDH) where, di-, and triHAAs were weaker inhibitors. MonoHAAs greatly reduced the ATP contents of the cells. Unlike monoHAAs, triHAAs increased the cellular ATP levels as compared to the negative controls. Exogenous pyruvate supplementation rescued cells from monoHAA-induced DNA damage and ATP depletion. These results confirmed that monoHAA-induced genotoxicity was due to GAPDH inhibition. HAAs not only affected the GAPDH kinetics and disturbed the cellular energy homeostasis but also increased pyruvate dehydrogenase complex (PDC) activity. Increased PDC activity by monoHAAs was due to changes in metabolite ratios e.g., ATP/ADP, and NADH/NAD ratio but the increase induced by di-, and triHAAs was due to the inhibition of pyruvate dehydrogenase kinase (PDK). Results demonstrated that HAA-induced toxicity is due to disruption in cellular energy homeostasis. This research demonstrated that there was a difference among the HAA-induced toxicity mechanisms and their molecular targets. MonoHAAs had an indirect effect on mitochondrial metabolism by inhibiting GAPDH, affecting the generation of pyruvate, inducing oxidative stress and reducing the final output of mitochondria in the form of ATP. Among monoHAAs, the rank order of toxicity was iodoacetic acid > bromoacetic acid >> chloroacetic acid (IAA > BAA >> CAA). This toxicity pattern was directly correlated with the inhibition of GAPDH kinetics, ATP depletion, and PDC activation. Whereas, di- and triHAAs induced toxicity by directly affecting mitochondrial metabolism by PDK inhibition, which led to PDC activation.
The toxicity potential of chlorinated and chloraminated wastewater effluents extracted with XAD-8 and XAD-4 resins was evaluated. For chlorinated water, the organic extracts eluted from XAD-8 were more cytotoxic than that of the chloraminated wastewater extracts.…

▼ By-products and mortalities from aquaculture have often posed significant challenges to the industry because of their low value resulting in high costs and environmental impact from their disposal. However increasing interest is being expressed in their utilisation to add value to the aquaculture industry and provide synergies with industries which had previously been in competition with aquaculture.
Current and prospective processing by-product and farm mortality utilisation strategies were reviewed along with regulations and standards which aim to control their use and protect against human and animal health hazards.
The role of aquaculture and fishery by-products in the supply of fishmeal was investigated and it was found that both sectors had the potential to contribute to increasing global supply. There were significant quantities of processing by-products identified which could be directed to fishmeal manufacture but there were also significant amounts of fish production which were not being processed in some regions and could also add to supplies. Processing by-products from aquaculture species often exceed 50% of the production by mass and therefore their efficient utilisation is of significant importance to the overall performance of the value chain. Their utilisation strategies are diverse and in some circumstances offer the possibility to add significant value.
Life Cycle Assessment (LCA) is increasingly being used to inform decision makers and consumers about the environmental performance of goods and services to make choices on best practices and informative decisions on purchasing choices. Current methodology in LCA was critiqued and developed to be used for identifying disproportionate impacts from by-product industries and comparative assessment of the eco-efficiency of value chains from Thai shrimp, Vietnamese Pangasius catfish and Scottish salmon aquaculture. New LCA methodology was developed assessing the eco-efficiency of co-products as a whole and in relation to a tonne of edible yield. Measuring the impact of the by-product industry in relation to their edible yield gave different results to measuring their eco-efficiency between the three study species. It was found that the Thai shrimp value chain was the most eco-efficient when by-products were directed to chitosan and hydrolysate manufacture, but production of the salmon was the least impacting between the species in terms of edible yield. Pangasius was the most environmentally impacting of the three species value chains using both methods. It was also found that the upstream impacts of fish and shrimp production, especially feed manufacture, contributed most to the environmental impact in most circumstances, using both economic and mass allocation. Although the methodology produced interesting results, there were some drawbacks and the data sets also had several gaps which led to some assumptions, which could have skewed the results and interpretation.

▼ In this thesis the kinetics of biosynthesis of lipids and their physiological role in the oleaginous Zygomycete Cunninghamella echinulata was studied during growth on media based on tomato by-products. During active growth and lipogenesis C. echinulata typically synthesizes triglycerides and lesser amounts of glycolipids plus sphingolipids (mono- and di-glycosylated diglycerides) and phospholipids (phosphatidyl-choline and phosphatidyl-ethanolamine etc). During growth gamma-linolenic acid (GLA) is transported from polar lipids to triglycerides. In fact, diglycosylated diglycerides followed by phosphatidyl-choline are the main sources of GLA. The major sugars of the glycolipids plus sphingolipids fraction are glucose and galactose, whereas rhamnose, mannose and arabinose are found in lesser percentages. The percentage proportion of glucose increases during growth. Ergosterol is the major sterol of C. echinulata (the rate of its synthesis increases during growth), while ergosta-5,7,9(11),22-tetraenol, ergosta-7,22-dienol, ergosta-7,22,24(28)-trien-3β-ol, episterol, and lanosterol are found in lesser percentages. During lipid mobilization triglycerides are preferentially degraded, while the degradation of GLA containing triglycerides proceeds with slower rates than the degradation of the rest triglycerides. On the contrary, polar lipids that contain high percentages of GLA are synthesized during lipid degradation. When C. echinulata is grown on a tomato by-product hydrolyzate supplemented with glucose it produces significant lipid amounts (47.6% of its biomass), corresponding to >1g/l GLA.
Στην παρούσα διδακτορική διατριβή μελετήθηκε η κινητική βιοσύνθεσης και ο φυσιολογικός ρόλος των λιπιδίων του ελαιογόνου Ζυγομύκητα Cunninghamella echinulata κατά τη διάρκεια της αύξησής του σε υποστρώματα με βάση παραπροϊόντα της βιομηχανίας της τομάτας. Κατά τις φάσεις της κυτταρικής αύξησης και της λιπογένεσης ο C.echinulata βιοσυνθέτει κυρίως τριγλυκερίδια και δευτερευόντως γλυκολιπίδια/σφιγγολιπίδια (μονο- και δι-γλυκοζυλιωμένα διγλυκερίδια) και φωσφολιπίδια (φωσφατιδυλο-χολίνη, φωσφατιδυλο-αιθανολαμίνη κ.ά.). Κατά τη διάρκεια της αύξησης το γ-λινολενικό οξύ (GLA) διακινείται απ' τα πολικά λιπίδια προς τα τριγλυκερίδια. Ειδικότερα, η μεγαλύτερη ποσότητα του GLA διακινείται απ' τα διγλυκοζυλιωμένα διγλυκερίδια και τη φωσφατιδυλο-χολίνη. Τα σάκχαρα που συμμετέχουν στις δομές των γλυκολιπιδίων και σφιγγολιπιδίων είναι η γλυκόζη και η γαλακτόζη και σε μικρότερα ποσοστά η ραμνόζη, η μαννόζη και η αραβινόζη. Μάλιστα, η περιεκτικότητα των γλυκολιπιδίων και σφιγγολιπιδίων σε γλυκόζη αυξάνεται κατά τη διάρκεια της αύξησης. Ο C. echinulata βιοσυνθέτει κυρίως εργοστερόλη (με αυξανόμενους ρυθμούς κατά τη διάρκεια της αύξησης), και σε μικρότερα ποσοστά εργοστα-5,7,9(11),22-τετραενόλη, εργοστα-7,22-διενόλη, εργοστα-7,22,24(28)-τριενόλη, επιστερόλη και λανοστερόλη. Κατά τη φάση της αποδόμησης των λιπιδίων τα τριγλυκερίδια αποδομούνται εκλεκτικά σε σχέση με τα υπόλοιπα λιπίδια, ενώ τα τριγλυκερίδια που περιέχουν στις δομές τους GLA…

▼ Chlorine is the most widely used disinfectant for disinfecting sewage effluents before their discharge into receiving water bodies. Hong Kong, where seawater is used for toilet flushing, has largely decided to use chlorine for disinfecting its 1.7 million cubic meters per day of saline sewage effluents. Upon chlorination, however, the extremely high levels of bromide ions in saline sewage effluents can be oxidized to hypobromous acid/hypobromite which could then react with the organics in the sewage effluents to form large quantities of brominated disinfection byproducts (DBPs). It has been demonstrated that brominated DBPs are significantly more toxic than their chlorinated analogues. The chlorinated saline sewage effluents with brominated DBPs are discharged into receiving water bodies. In Hong Kong, the receiving water body is the coastal marine water, which covers 41 gazetted swimming beaches and many ecologically sensitive habitats. Due to the shortage of fresh water resources, many coastal cities around the world may adopt the practice using seawater for toilet flushing. Therefore, detection, formation and toxicity of brominated DBPs during chlorination of saline sewage effluents have become an imminent issue that needs to be investigated and evaluated. In this study, a precursor ion scan method with electrospray ionization triple quadrupole mass spectrometry (ESI-tqMS) with/without ultra performance liquid chromatography (UPLC) preseparation was improved. The improved method was then applied to fast selective detection of polar brominated DBPs in disinfected wastewater. Numerous polar brominated DBPs were detected in chlorinated saline sewage effluents; many of them are new brominated DBPs that have not been reported previously; three of them including 5-bromosalicylic acid (5BSA), 2,6-dibromo-4-nitrophenol (DBNPh) and bromomaleic acid (BMA) were identified with authentic standard in chlorinated saline sewage effluents. The formation of polar brominated DBPs, especially those newly detected ones, were studied for the first time in chlorinated primary and secondary saline sewage effluents. For a secondary saline sewage effluent, the number and levels of brominated DBPs formed during chlorination varied with chlorine dose. The numbers of brominated DBPs formed at chlorine doses of 6 and 10 mg/L as Cl2 were similar, and more brominated DBPs formed at chlorine dose of 15 mg/L as Cl2. Over 18 nitrogenous brominated DBPs were detected in the chlorinated secondary saline effluent, and most of them reached their maximum intensities at chlorine dose of 10 mg/L as Cl2. The application of chlorine dose at breakpoint without significant free chlorine residual generally reduced nitrogenous DBP formation in the chlorinated secondary saline effluent with well nitrification. The formation of total organic halogen (TOX) increased with chlorine dose from 6 to 10 mg/L as Cl2, but did not increase further when chlorine dose was increased to 15 mg/L as Cl2; also, a higher total organic bromine (TOBr) to TOX ratio was observed at…

▼ Disinfection is one of the most significant steps to guarantee the quality, safety, and shelf-life of fresh and fresh-cut produce in food processing industry. However, the disinfectant can react with the organic matter in produce and water, leading to the formation of disinfection byproducts (DBPs), which pose potential carcinogenic risks to human health. Despite the common use of disinfectants in produce processing and extensive research of DBPs in the drinking water field, studies investigating the DBP levels in fresh produce are quite limited. The research objectives of this thesis are to conduct a critical literature review regarding DBP occurrence and formation potential in fresh produce and produce process water, summarize the analytical methods, assess DBP exposure and risks, explore the current knowledge status, identify major information gaps, and provide recommendations for future research. It has been found that the majority of the existing studies focused on investigation of THM residues in fresh produce and associated process water. Process water contains significant levels of DBPs due to high organic load, indicating that more challenges can arise in treating and recycling process water. Future research should look into gathering more comprehensive data on DBPs in food, particularly for emerging nitrogenous DBPs, developing disinfection strategies alternative to chlorine with both disinfection efficacy and DBP minimization in consideration, and improving the risk assessment methods for DBPs in food.

▼ The nutritive values of two fishery by-
products, i.e. fish
protein hydrolysate (FPH) and liquefied fish (LF), were studied.
Three trials using Hubbard broilers, and Yorkshire pigs (starter
and grower phase) were conducted. The FPH was used in the broiler
trial and LF in the swine grower trial as supplemental protein
sources, that replaced partially the soybean meal protein. The FPH
was used to completely substitute for the skim milk component in
milk replacer for the pig starter trial. Sensory evaluation of
the edible tissue was conducted at the end of the broiler and swine
grower trials to evaluate the carcass quality changes associated
with feeding fish-containing diets.
The FPH derived from four different substrates (Hake, Dover
sole, Brown rock cod and Atlantic cod) were incorporated into diets
to provide 5% of the total dietary protein in the broiler trial and
compared to Herring meal and soybean meal diets. Mean body weight
(MBW) and feed conversion (FC) were determined when chicks were 4
weeks of age. The MBW of chicks fed the Hake, Brown rock diets
were lower (P<.05) than those fed the corn-soy, Herring and Atlantic cod meal diets. However, FC was found not to be influenced
(P>.05) by the supplemental protein sources. Edible tissue samples
were subjected to a sensory evaluation. Fishy flavor and off-flavor
were detected (P<.05) in carcasses of broilers fed Herring and
Dover sole meal. Juiciness of meat was the same (P>.05) in all
broilers receiving different diets.
LF, prepared from Dover sole fillet scraps, was formulated to
provide 24% (7.4% LF) or 12% (3.4% LF) of the total dietary protein
in the rations for the swine grower trial. Initial weight for
pigs used in the grower trial ranged from 26-28 kg. Pigs receiving
the diet containing 7.4% LF had lower FC (P<.05) and average daily
gain (ADG) (P<.01) than either the 3.7% LF or control groups.
Growth of pigs fed the 3.7% LF group was not different (P>.05)
from the control group. Similar results were obtained from the
sensory evaluation of the edible tissue. Flavor, juiciness and
overall desirability of edible tissue from pigs finished on 7.4% LF
diet were different (P<.05) from pigs fed either the 3.7% LF and
control. No difference (P>.05) in carcass quality was observed
between 3.4% LF group and the control group.
Milk replacer diets containing either skim milk or FPH
contributed 20% of dietary protein, were fed to young pigs from
6.7 to 22.5 kg of body weight. .FC and ADG were not different
(P>.05) between groups. The scouring problem was more severe in
FPH fed pigs. However, the nutritive value of fish protein was
shown to be similar to milk protein in the milk replacer diet for
piglets. Based on the results of these trials, protein sources derived
from fishery wastes can be effectively used as supplemental protein
sources for poultry and swine. Adverse effects in carcass quality
might be obtained if they are used at high levels.

▼ vii, 89 leaves, bound ill. 29 cm
Following a factorial experimental design, a series of tests were performed to investigate the effects of operating parameters; oxygen to carbon ratio (O/C), steam to carbon ratio (SIC) and temperature (T), on reforming glycerin to a H2 rich gas. A mathematical model defining the effect of those three variables was derived., and used for improving the reaction hydrogen yield. From the range of experimental conditions tested it was concluded that OIC, as well as the interaction between OIC and temperature had the most important effects on H2 yield. 4.5 mole of hydrogen were produced per mole of glycerin at experimental conditions of O/C=1, S/C=2.2, and T=804°C. This is 65% of the maximum theoretical yield, and 90% of the yield predicted by thermochemical equilibrium. 1.4 moles of carbon monoxide per mole of glycerin were also produced., presenting a potential for an additional 1.4 mole hydrogen per mole glycerin. A water gas shift reaction was then used., and its operating temperature optimized, in order to convert the reformate gas CO into hydrogen by combining it with water. Results were satisfying, with a final yield of 5.3 moles H2 I mole glycerin, which is 75% of the maximum stoichiometric hydrogen yield. Crude glycerin, obtained from biodiesel production, was finally tested (without a water gas shift) as a feed to compare it with pure glycerin used throughout the tests. The initial results were very encouraging, almost identical to those of pure glycerin, but carbon formation quickly became a problem. Possible contaminants causing the coking may include methanol, chloride and sodium cations, and free fatty acids, all present in crude glycerin as byproducts of biodiesel synthesis.

▼ Chloramination has gained increasing popularity in drinking water disinfection but may lead to increasing formation of nitrogenous disinfection byproducts (N-DBPs). Transformation pathways of chloramination of nitrogenous organic compounds are largely unclear. This thesis work investigated transformation pathways of chloramination of three model nitrogenous organic compounds including 4-amino-2-chlorobenzoic acid (ACBA), phenylalanine (PHE) and cytosine (CYT) with variations in reaction time, monochloramine dosages, and pH. Structures of the intermediates and products were elucidated by a numbers of mass spectrometry techniques. The number and origins of nitrogen atoms in the products are determined by a labeled 15N-monochloramine method. Chloramination of the model compounds underwent several cycles of chlorine substitution and hydrolysis, which were affected by reaction time, monochloramine dosages, and pH. Chlorine atoms firstly substituted hydrogen atoms either on the aromatic rings containing electron donating functional groups (e.g., ACBA and CYT) or on the amine groups on the aliphatic side chain (e.g., PHE). Most of these chlorine-substituted intermediates formed within 4 hours to 1 day and decayed with further increasing reaction time. During the continuous chloramination, large molecular weight compounds containing aromatic rings underwent ring cleavage to form low molecular weight aliphatic compounds. At high Cl/P molar ratios, more chlorine atoms are added to the products. At lower pH, a larger number of products were formed and identified. Chloroimino intermediates were identified in chloramination of PHE and CYT, and their nitrogen atoms mainly originated from the model nitrogenous compounds. This thesis work reveals that chloramination of nitrogenous organic compounds can initiate with chlorine substitution of the ring structures, in addition to commonly known chlorine substitution of the amine groups. The weak monochloramine attack on the chlorine substituted compounds can also lead to ring opening and finally formation of more nitrogenous DBPs, with increasing contact time. Therefore, special attention shall be paid to nitrogenous DBP formation in large water distribution systems (with long holding time) using monochloramine for residual protection. The N-DBP formation can be reduced by controlling the source of nitrogenous organic compounds. The formation can also be reduced by maintaining lower monochloramine concentrations and/or higher pH.

▼ Chlorinated aromatics undergo surface-mediated reactions with metal oxides to form environmentally persistent free radicals (EPFRs) which can further react to produce polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs). Previous work using laboratory-made fly ash surrogates composed of transition metal oxides deposited on silica powder has confirmed their ability to mimic fly ash in the production of PCDD/Fs. However, little is known about the propensity of alumina and aluminosilicates to form PCDD/Fs. Cooperative catalysis between transition metals in the formation of PCDD/Fs has also seen little research. A fly ash sample containing both alumina and mullite, an aluminosilicate, was tested for PCDD/F formation ability and compared to PCDD/F yields from the thermal degradation of 2-monochlorophenol (2-MCP) precursor over γ-alumina, α-alumina, and mullite. A series of fly ash surrogates with varying amounts of co-deposited iron (III) oxide and copper (II) oxide, both known to increase PCDD/F formation individually, were also investigated. A packed-bed flow reactor was used to investigate the thermal degradation of 2-MCP over the various catalysts at 200-600 ⁰C. Fly ash gave similar PCDD/F yields to surrogates made with similar transition metal content. γ-alumina, which is thermodynamically unfavorable, was very catalytically active and gave low PCDD/F yields despite a high destruction of 2-MCP. Mullite and α-alumina, the thermodynamically favorable form of alumina, yielded higher concentrations of dioxins and products with a higher degree of chlorine substitution than γ-alumina. The data suggests that certain aluminas and aluminosilicates, commonly found in fly ash, are active in the formation of PCDD/Fs in the post-flame cool zones of combustion systems and should be considered as additional catalytic surfaces active in the process. The bimetallic surrogates were found to be extremely catalytically active, suggesting synergistic effects between Fe and Cu in real incineration systems. Under oxidative conditions, the bimetallic surrogates completely catalytically oxidize the 2-MCP precursor and exhibit low yields of PCDD/Fs. Under pyrolytic conditions, the bimetallic surrogates give extremely high yields of PCDD/Fs. The comparisons between transition metal and non-transition metal effects on PCDD/F formation represents a new step forward in our understanding of PCDD/F emissions from incineration systems.

▼ Chlorination is used to prevent the spread of waterborne infectious diseases from swimming pools. This required disinfection practice also results in the formation of undesirable disinfection by-
products (DBPs) from the reactions of chlorine with the organic matter (released by swimmers or present in the filling water of the pool) and bromide. Some of these DBPs have important adverse public health effects; as a result their concentrations in drinking waters are regulated. Unfortunately, DBPs formation and control in swimming pools have not been studied and investigated to the same extent as their formation and control in drinking water. The main objective of this research was to improve our understanding of the occurrence and formation of DBP classes: trihalomethanes (THMs) [Trichloromethane (TCM), bromodichloromethane (BDCM), dibromochloromethane (DBCM), and tribromomethane (TBM)], haloacetic acids (HAAs) [chloroacetic acid (CAA), bromoacetic acid (BAA), dichloroacetic acid (DCAA), bromochloroacetic acid (BCAA), trichloroacetic acid (TCAA), bromodichloroacetic acid (BDCAA), dibromoacetic acid (DBAA), dibromochloroacetic acid (DBCAA), and tribromoacetic acid (TBAA), and halonitromethanes (HNMs) [chloronitromethane (CNM), dichloronitromethane (DCNM), trichloronitromethane (TCNM), bromonitromethane (BNM), bromochloronitromethane (BCNM), bromodichoronitromethane (BDCNM), dibromonitromethane (DBNM), dibromochloronitromethane (DBCNM), and tribromonitromethane (TBNM)] under swimming pool operation conditions as practiced in the US and estimate their potential adverse health impacts on swimmers and lifeguards. During the occurrence study conducted during this research, the occurrence of N-nitrosodimethylamine (NDMA) and haloacetonitriles (HANs) [chloroacetonitrile (CAN), trichloroacetonitrile (TCAN), dichloroacetonitrile (DCAN), bromoacetonitrile (BAN), bromochloroacetonitrile (BCAN), and dibromoacetonitrile (DBAN)] were also investigated. Specifically, the objectives of the research were: (1) to examine the occurrence of the five DBPs (THMs, HAAs, HNMs, NDMA, and HANs) in indoor swimming pools in the US, (2) to conduct a multi-pathway risk assessment on THMs (TCM, BDCM, DBCM) and two HAAs (DCAA and TCAA) of swimming pool water, (3) to determine the role and contribution of the two main precursors (i.e., filling water natural organic matter (NOM) vs. body fluids (BF) from swimmers) to the formation of THMs, HAAs), and HNMs in swimming pools, (4) to investigate the impacts of swimming pool operational parameters: free available chlorine (FAC), pH, bather load (TOC), water bromide content, and temperature on the formation and speciation of THMs, HAAs, and HNMs, and (5) to measure the formation of THMs and HAAs from the body fluids during turnover time, 'the period of time (usually hours) required to circulate the complete volume of water in a pool through the recirculation system' of swimming pool water. The occurrence of DBPs was investigated by collecting samples from 23 indoor pools in South Carolina,…

▼ Per- and poly-fluoroalkyl substances (per- and poly-PFASs) are emerging contaminants that have raised great concern in recent years. Two anionic per-PFASs in particular, perfluorooctane sulfonate (PFOS) and perfluorooctanoate (PFOA), has received worldwide attention for their persistence in the natural environment, resistance to typical environmental degradation, bioaccumulation potential, and adverse health effects in humans. The stable chemical characteristics have enabled these chemicals to be used in many industrial and consumer
products over the past 50 years. They have been detected all over the world in various environmental matrices.
The water treatment removal of per-PFASs has been well documented, but the full classification of PFASs has yet to be determined and new compounds are being discovered and tested. Recent studies have identified numerous cationic and zwitterionic poly-PFASs whose fate and removal during drinking-water and municipal wastewater treatment remain unclear. However, there is limited knowledge on the fate of these emerging PFASs in water treatment processes. Studies on the removal mechanisms of cationic and zwitterionic poly-PFASs are needed to select the efficient treatment approaches while limiting the secondary formation of PFOS and PFOA. Furthermore, a few recently manufactured poly-PFASs as PFOS/PFOA alternatives have been found in drinking water and environmental samples. As the use of certain PFASs are being phased out of major manufacturers to reduce emissions, alternative PFAS compounds may start to become more detected in aquatic environments, which creates many unknowns for removal methods.
The goal of this project is to examine the removal of PFOS/PFOA alternatives and precursors and to model cationic and zwitterionic poly-PFAS compounds during conventional, enhanced, and advanced drinking-water treatment systems. Various water treatment technologies were investigated with regard to the removal and transformation of cationic and zwitterionic PFASs and PFOS/PFOA alternative compounds, including, enhanced coagulation, filtration, advanced carbon adsorption, chlorination, and ozone treatment to determine removal possibilities. These cationic and zwitterionic poly-PFASs have similar chemical structures as PFOS and PFOA, and our data as shown below indicate that certain cationic and zwitterionic poly-PFASs can convert to PFOS and PFOA during water disinfection processes with chlorine or ozone. The results of this work will shed light on the overall contribution of precursor compounds to the formation of PFOS and PFOA in engineered environmental systems.
It was determined that the removal of the target PFASs during conventional techniques, coagulation, and sand filtration was low. As for filtration by activated carbon, the concentrations immediately were almost below detectable ranges proving its wide known effectiveness against the removal of longer chained PFASs. Disinfection technique, chlorination, was found to be…

▼ The objectives of this study were to evaluate the effects of corn and dried distiller’s grain fed as a prebreeding flushing supplement on weight gain and body condition, breeding and subsequent lambing rate, and early postnatal growth of Rambouillet ewes. Treatment groups consisted of 1 control group (n=30) that was not fed a supplement, 1 group (n=30) that was fed a corn based ration, and 1 group (n=30) that was fed a dried distiller’s grain based ration. After the feeding period concluded, lamb data was collected to determine what, if any, change occurred. No differences (p < 0.05) were detected in body weight over time or on the number of ewes that conceived. However, significant differences (p > 0.05) were found in body condition score, number of lambs born, and 30 and 60 day weights of lambs. While flushing supplementation slowed down weight loss, there was no significant difference detected in reproductive efficiency.

▼ USEPA regulations of Disinfection By-
Products (DBPs) require water suppliers to be in compliance with maximum contaminant levels set by the agency’s Stage 2 DBP Rule. Controlling watershed sources of byproduct precursors are of interest to water suppliers. By-product formation potential and DOC (dissolved organic carbon) character were evaluated at eight sites on four dates (n=32). All sites are within Springfield Water and Sewer Commission’s Cobble Mountain Reservoir watershed (Blandford and Granville, Ma). The goal was to investigate how DBPFP (DBP formation potential) changes in relation to landscape driven changes in DOC chemical characteristics. Analysis was performed on raw water samples using UV-Visible Spectroscopy. 1H Nuclear Magnetic Resonance Spectroscopy (NMR), and Fourier Transform Infrared Spectroscopy (FT-IR) were performed on solid phase extractable (SPE-C18) hydrophobic DOC. Changes in DBPFP are related to landscape changes in hydrophobic DOC characteristics. On three of the four sample dates (n=24) DBPFP was positively correlated to the E2:E3 ratio (R2=.37), SUVA (R2=.72), percent aromatic resonance (R2=.60), and percent carbohydrate resonance (R2=.44). DBPFP on three sample dates (n=24) was negatively correlated to percent aliphatic resonance (R2=.48). DOC aromaticity, SUVA and specific formation potential were lowest in headwater streams and increased with distance downstream. Substantial reductions in DOC concentration are seen upon reservoir export. For most parameters headwater in-stream variability was greater than inter-stream variability. Differences among headwater streams of different forest type are not distinguishable in our small sample size (n=12). Only slight differences in specific formation potential were observed among two different depth samples in Cobble Mountain Reservoir. Our results have implications for watershed management practices in the drinking water supply industry of New England.

▼ AN EXAMINATION OF THE EFFECTS OF USING GLYCEROL AND WHEAT DRY DISTILLERS’ GRAINS WITH SOLUBLES IN SHEEP DIETS
The aims of this research were to assess the effects of feeding glycerol and wheat based dry distillers’ grains with solubles (WDDGS) on rumen metabolism, performance, carcass characteristics and fatty acid composition of adipose tissue of lambs. In study 1, increasing levels of glycerol as replacement of barley grain in in vitro batch cultures did not affect culture pH and total methane (CH4) production, but in vitro dry matter disappearance, total VFA production and propionate proportions were linearly increased. In study 2, increasing levels of glycerol in a forage diet increased total VFA, propionate and butyrate production and DM and neutral detergent fibre (NDF) disappearance in semi continuous fermenters. Methane production was linearly increased despite increases in propionate concentrations as a result of the more reduced state of glycerol as compared to carbohydrates which implies there is no net incorporation of electrons into glycerol when it is metabolised to propionate. In study 3, increasing concentrations of glycerol did not alter in vivo diet digestibility or CH4 production. However, dry matter intake (DMI) was reduced at high glycerol concentrations (210 g/kg DM) and average daily gain (ADG) tended to decrease. Fatty acid profiles were improved by reducing concentrations of palmitic, trans-10 octadecenoic and linoleic acids and the n-6/n-3 ratio and increasing stearic and oleic acids.
In study 4, increasing concentrations of WDDGS as direct replacement of barley grain resulted in increased eating rates, DMI and ADG. Linolenic acid in backfat tissue was also increased without altering the n-6/n-3 ratio. However, when WDDGS were included in iso nitrogenous diets as replacement of soybean meal and alfalfa, DM, NDF and CP in sacco effective degradability and in vitro CH4 production were increased. Animal DMI, ADG and hot carcass weight were linearly reduced but feed efficiency was unaffected and trans-10 octadecenoic and linoleic acids were increased.

▼ [EN] Sustainability is nowadays an investment for the future of any economic activity. The current situation of crisis has had an adverse impact in most industries, including the agri-food sector. However, this industry has been relatively the least affected when compared with other industrial sectors. This is mainly attributed to the fact that food
products continue to be basic for consumers despite the economic downturn. Therefore, the agri-food sector is a key element in the European economy and can play a crucial role in the achievement of the objectives set in the EU's strategy for 2020: ensuring a sustainable framework of growth of a more competitive economy. The European agri-food industry has focused on energy efficiency and on reducing greenhouse gases emissions, along with better management of their resources as a way to improve its industrial competitiveness. In this sense, the search for solutions to transform the by-
products generated in high value-added ingredients, is a priority. In this context, the juice industry, as fundamental sub-sector within the food sector, and large waste generator, must exploit the opportunity to transform their by-
products into useful and profitable
products for society. This transformation presents some difficulties which impede the profitability of the process. These difficulties are associated with the by-product, such as its compositional variability and its seasonality, and current techniques of transformation as the high energy cost in dehydration processes. This thesis represents an innovative and sustainable solution for overcoming the disadvantages associated with the high costs of stabilization, turning this by-
products into high value-added ingredients, from both, nutritional and technological, points of view. The aim is to develop a microwave coupled with hot air drying technique allowing maximizing profits by using the following strategy: reducing time and operational costs, producing a new ingredient rich in dietary fiber, with interesting technological properties for the development of healthy foods, studying the proposed comprehensive process and analyzing the new generated by-
products.
The methodological approach of the thesis been focused, on the one hand, on studying phenomena that govern the internal transport of water and energy through the orange peel during its dehydration applying thermodynamics. On the other hand, the energy consumption of the drying process, the technological and sensory properties of the fiber obtained and its potential use as a fat substitute have been compared with the conventional hot air drying method. Finally, the integrated process, including both the combined drying technique and the pretreatments needed for colour and bitter compounds extraction, is proposed as a new route of
valorization, in which the new by-
products obtained, polyphenols and carotenoid rich extracts, are analysed. This study has analyzed the microwave coupled with hot air process, developing tools that allow the adequate upscaling of the drying…

▼ In the Western Cape, South Africa and other regions globally, grape pomace (GP) is one of the abundant agro-waste from the winery industry. This study reports on the hyper-extraction of fermentable sugars from GP treated with white rot fungi (WRF) Phanerochaete chrysosporium BKMF 1767 to facilitate improved biovalorisation for total reducing sugars (TRS) extraction in conjunction with Nepenthes mirabilis digestive fluids. TRS were quantified using the 3,5-dinitrosalicylic acid (DNS) reagent method. The free readily dissolvable sugars from the GP recorded for the bio-treated (BT) samples was 206.39 ± 0.06 mg/L and for the untreated (UT) samples was 271.05 ± 0.02 mg/L. Overall, the TRS yield for the Bio-treated (BT) and untreated (UT) samples was recorded as 205.68 ± 0.09 and 380.93 ± 0.14 mg/L, respectively, using hot water pretreatment (HWP) with 2266.00 ± 0.73 (BT) and 2850.68 ± 0.31 mg/L (UT), respectively, for dilute acid pretreatment (DAP); with 2068.49 ± 6.02 (BT) and 2969.61 ± 8.054 mg/L (UT) respectively, using the cellulase pretreatment (CP) method. Using the HWP as a reference, the relative increases imparted by the biotreatment was higher (51%) for DAP and low (33%) for CP. The combination of conventional used pre-treatment methods (hot water pretreatment, dilute acid pre-treatment, and cellulase pre-treatment) in a single pot system was also done while monitoring the total residual phenolics (TRPCs) in the samples. Furthermore, powder X-ray diffraction (pXRD) were used to measure the crystallinity index (CrI) and functional groups of pre- and post-pretreated GP to ascertain the efficiency of the pre-treatment methods, with quantification of lignin, holocellulose, and ash. Overall, the TRS yield for N. mirabilis pre-treated agro-waste was 951 mg/L ± 4.666 mg/L, with biomass having a lower CrI of 33%, and 62% residual lignin content. Furthermore, reduced TRPCs were observed in hydrolysate, suggesting limited inhibitory by-product formation during N. mirabilis pre-treatment

Les produits les plus présents sont les trihalométhanes (THMs), les acides haloacétiques (HAAs). Des études toxicologiques (animales et in vitro) ont montré la génotoxicité et/ou carcinogénicité et la reprotoxicité de certains SPCs. Nous avons mené deux études évaluant les effets sur la santé humaine de l’exposition aux SPCs, dans le domaine du cancer et de la reproduction. Association entre exposition aux THMs et risque de cancer de la vessie : une analyse poolée de 3 études cas-témoins européennes. Cette analyse a inclus 2381 cas et 3086 témoins issus de 3 études cas-témoins (France, Espagne, Finlande). L’exposition environnementale aux SPCs a été mesurée par la concentration en THMs estimée rétrospectivement dans les réseaux de distribution d’eau au cours des 40 années de la fenêtre d’exposition. Les usages de l’eau connus sont l’ingestion, les douches et les bains, la fréquentation de piscine (étude espagnole seulement). Une relation croissante a été observée entre le niveau environnemental de THMs, la durée d’exposition à une eau de surface chlorée et le risque de cancer de la vessie, chez les hommes uniquement. Aucune association n’a été observée avec l’exposition via l’ingestion d’eau du robinet. L’exposition via les douches, les bains et la piscine est apparue liée au risque de cancer de la vessie. Trois études cas-témoins nord-américaines ont été intégrées dans une méta-régression. Aucune spécificité européenne de la relation dose-réponse n’a été mise en évidence. Une relation dose-réponse globale incluant 4351 cas et 7055 témoins a été estimée. Association entre exposition aux SPCs et risque de prématurité et de retard de croissance intra-utérin (RCIU). Cette étude est issue de la cohorte bretonne Pélagie (3400 femmes enceintes recrutées en début de grossesse entre 2002 et 2006). L’exposition pendant la grossesse a été mesurée à l’aide de 2 indicateurs : la concentration en THMs de l’eau distribuée dans les réseaux et le dosage d’un biomarqueur urinaire (acide trichloroacétique) pour un sous-échantillon de femmes (étude cas-témoins nichée). Les niveaux dans les réseaux proviennent de la base de données réglementaire SISE-Eaux. Les usages de l’eau du robinet par les femmes pendant la grossesse ont été collectés par questionnaire (quantité d’eau du robinet bue, fréquentation de la piscine, fréquence et durée des douches et des bains). Notre étude suggère une association entre l’exposition prénatale aux SPCs et le risque de RCIU. Aucune association n’est observée avec le risque de prématurité.

▼ The presence of anthropogenic substances into the aquatic environment is one of the major milestones that environmental chemistry has to confront nowadays. In the last decade, drugs of abuse have joined the group of compounds identified in this environmental compartment, showing that the aquatic environment is a clear reflection of the activities and habits of those who are directly affecting it, the human beings. The important worldwide consumption of these substances, and their excretion, either unaltered or as known metabolites, explains their presence at detectable concentrations in the aquifer where they arrive via wastewater.
In this thesis, an analytical method for the determination of drugs of abuse in aqueous matrices by ultra performance liquid chromatography coupled to tandem mass spectrometry has been developed. Once established, this method has been used for the determination of drugs of abuse in wastewaters, which revealed the presence of twelve out of fifteen drugs of abuse, such as caffeine, nicotine, cocaine or ecstasy among others, over the forty wastewater treatment plants studied throughout the Catalan geography. Some of these substances, despite being partially removed during treatment, are also present in the effluents discharged to surface waters. The study of surface waters also showed the presence of some drugs of abuse, such as cocaine or ecstasy among others, along the Llobregat river basin, studied birth to mouth, to evaluate the effects of multiple factors involved such as wastewater discharges, natural attenuation or effect of dilution and/or concentration that may have some of its effluents. The results show an increasing trend in the concentrations of drugs of abuse as the river approaches the most densely populated areas with higher environmental pressures. Seasonal and weekly variations have been also conducted in both wastewater and surface waters. For some compounds, such as ecstasy (MDMA), significant increases can be found over weekends, probably due to its recreational use, while for cocaine only slight increases were detected during these days, suggesting therefore a more sustained consumption. During specific times, such as Christmas, notable increases in the concentrations of some substances such as cocaine or ecstasy have been also observed. The presence of drugs of abuse in surface waters used for the production of drinking water has led in the last part of this work to study the behavior of these substances in drinking water treatments. This study has been extended to another family of anthropogenic pollutants, pharmaceuticals. The results have shown that, while most drugs of abuse and pharmaceuticals studied are efficiently removed, some are able to survive and remain in the final water at low concentration levels. Furthermore, along with these more recalcitrant compounds, the study of formation and presence of byproducts of the amphetamine type stimulants disclosed the formation of two chlorinated disinfection byproducts, one of which is even able to survive the…

▼ Dans ce travail, nous avons étudié la dégradation de la sulfaclozine, un antibiotique, dans des solutions aqueuses par photocatalyse (TiO2 en suspensions) ainsi que par oxydation par les ions persulfate. L'utilisation d'inhibiteurs spécifiques (KI et alcools) nous a permis de comprendre l'intervention de chacune des espèces réactives (électrons, trous, radicaux •OH) dans la dégradation de la sulfaclozine. En outre, l'identifications des produits de dégradation par LC-MS/MS et le suivi de leur cinétique d'apparition et de disparition avec et sans alcool nous a permis de proposer un mécanisme de dégradation photocatalytique faisant intervenir les trous, les radicaux •OH, les électrons, et les radicaux O2•–. Nous avons également évalués plusieurs méthodes d'activation du persulfate (UV, irradiation solaire, UV/TiO2 et Fe(II)) afin de générer des radicaux SO4•– pour dégrader la sulfaclozine. Nous avons montré qu'à pH 7, le système présentant la plus grande efficacité quelque soit la concentration de persulfate, était le système UV/TiO2/K2S2O8. L'utilisation des inhibiteurs spécifiques des radicaux •OH et SO4•– a permis de constater que le pH a un effet important sur le rôle de chacun de ces radicaux dans la dégradation de la sulfaclozine. Les constantes de vitesse de la réaction de la sulfaclozine avec les radicaux •OH et SO4•– ont été déterminées et des valeurs proches ont été trouvées (?109 M-1s-1). Nous avons également étudié l'effet des principaux ions constituants de l'eau sur la dégradation de la sulfaclozine dans les trois systèmes suivants: UV/TiO2, UV/TiO2/K2S2O8 et UV/K2S2O8. Cette étude a montré que les bicarbonates et les phosphates accélèrent la dégradation photocatalytique alors qu'aucun effet n'a été observé dans le système UV/K2S2O8. En ce qui concerne les ions chlorures et nitrates nous avons montré qu'ils augmentaient l'adsorption de la sulfaclozine à la surface de TiO2 mais n'accéléraient pas significativement la réaction de dégradation
In this work, we studied the degradation of the antibiotic sulfaclozine in aqueous solutions by photocatalysis (on TiO2 suspensions) as well as by persulfate ions. The use of specific inhibitors (KI and alcohols) allowed us to understand the intervention of each of the reactive species (electrons, holes, radicals •OH) in the degradation of sulfaclozine. In addition, the identification of the by-products by LC-MS / MS and the monitoring of their appearance and disappearance kinetics, allowed us to propose a photocatalytic degradation mechanism involving TiO2 holes, •OH radicals, electrons, and O2•– radicals. We also evaluated several methods for persulfate activation (UV, sunlight, UV / TiO2 and Fe (II)) to generate SO4•–. We have shown that at pH 7, the system having the highest efficiency, regardless of persulfate concentration, was the UV/TiO2/K2S2O8 system. The use of specific inhibitors of •OH and SO4•– radicals showed that pH has a significant effect on the role of each of these radicals in the sulfaclozine degradation. Moreover, the reaction rate constants of…

▼ The experimental work of this PhD thesis has been scheduled on a three-axis base. Theaims that were set, they concerned the optimal exploitation of four different by-products of the table olive, olive oil and olive kernel oil industries, for the recovery of specific highadded-value compounds with well-known biological properties. Those natural productswere desired either in the form of enriched fractions or pure compounds. The prerequisitewas to utilize as eco-friendly technologies as possible for extraction and purification and tooptimize the processes in laboratory as well as in pilot scale. Thus, trustworthy estimationof industrial feasibility is provided. The main technologies that were implicated for therecovery of the target compounds are: Supercritical fluid extraction Pressurized liquid (and subcritical water) extraction Liquid/liquid extraction Adsorption resin technology Centrifugal Partition ChromatographyThe by-products that were the subject of the tracing/ extraction/ enrichment/identification/ quantification on studies for this PhD thesis were the following: Olive leaves (by-products of the pruning of the trees and of the olive fruit harvest) Olive mill pomace waste (biphasic process) Table olive process wastewater (by-product of the debittering process for theproduction of table olives) Olive kernel oil deodorization distillates (by-product of the refining process for theproduction of olive kernel oil from olive pomace)The natural compounds that were targeted for their recovery, enrichment and isolation dueto their well-established (and still under research) biological properties and theirapplication in pharmaceutical, phytotherapeutical, nutraceutical, cosmetic andcosmeceutical industries were respectively: Oleuropein Hydroxytyrosol SqualeneIn all cases, not only biomarkers’ content but also the overall chemical profile of theextracts was studied. The applied scientific interest of this work was that novel green extraction technologies and combinatorial processes as well as experimental design wereimplemented in lab and pilot scale for the exploitation of certain by-products that occur invery large quantities every year as a result of the agricultural/ industrial processing of theolive tree, with the aim of recovering high added value natural products.

▼ Submitted in fulfillment of the academic requirements for the Masters in Applied Sciences (Chemistry), Durban University of Technology, Durban, South Africa, 2016.
The main aim of this work was to produce levulinic acid (LA) from sugarcane bagasse (SB) and since there is approximately 3 000 000 tons of bagasse produced per annum by 16 factories that are located on the north coast of Kwa-Zulu Natal, after the extraction of sugar.
For this project fructose was firstly used for the production of LA, thereafter SB was used to produce LA. Cellulose was extracted from sugarcane bagasse using two types of pre-treatments namely (i) acid-alkali pre-treatment and (ii) liquid hot water (LHW). In the latter method acid hydrolysis and enzymatic hydrolysis was used to hydrolyse cellulose to glucose.
For the acid-alkali pre-treatment work, two types of bagasse was used namely (i) mill-run bagasse and (ii) depithed bagasse and for the LHW a mill-run bagasse (pellets form) was used.
In both pre-treatment methods the glucose solution was then acid catalysed by two different acids (i) an environment friendly acid, methanesulfonic acid (MSA) and (ii) sulphuric acid, producing levulinic acid. The results showed that MSA and sulphuric acid produced almost the same yield of LA but, MSA is preferred for the production of LA since it is less toxic and less corrosive than sulphuric acid.
