▼ An outbreak of Middle East Respiratory Syndrome (MERS) among healthcare workers in Saudi Arabia in 2012 led to an investigation of hand-hygiene behaviors among healthcare professionals. Direct contact with patients is a major pathway for MERS, a droplet virus, which refers to a virus that lays on surfaces. This study investigated factors associated with respiratory disease transmission (e.g., MERS) in hospital settings among healthcare workers (i.e., physicians and nurses). I developed a 16-item checklist based on three sources: the CDC standards, the WHO Five Moments for Hand Hygiene, and Boyce and Pittet's (2002) guidelines of hand hygiene. I used those 16 items in both direct-observation and self-reported questionnaire formats. The checklist addressed three time frames of contact: before, during, and after contact with patients, devices, and surrounding surfaces. Hand-hygiene behaviors surrounding these time frames were assessed. The study also explored healthcare workers' beliefs about hygiene practices by comparing personal reports of hand hygiene assessed by questionnaire to observed actual hand-hygiene practices. The study was a cross-sectional research design and was conducted in the outpatient examination rooms and emergency departments of three hospitals (public, private, and military) in the Eastern region of Saudi Arabia. The total sample size included 87 physicians and nurses who were recruited while on duty during the researcher's observation periods. To provide clear results, I used two independent sample t-tests to test each of the 8 hypotheses. I found that no statistically significant differences were found among health-care workers when observing their behaviors of hand-hygiene practices. However, when using the self-reported questionnaire data, I found statistically significant differences between physicians' and nurses' hand-hygiene practices before, during, and after interacting with patients. Also, I found statistically significant differences between male and female hand-hygiene practices during interacting with patients, and I found statistically significant differences between health-care workers in public and military hospitals hand-hygiene practices during interacting with patients. For the primary hypothesis, I used Pearson correlation to determine the relationship between healthcare workers' reports of hand-hygiene practices, and observed healthcare workers behaviors of hand-hygiene practices. I found that no statistically significant correlation between the two data collection instruments. To provide a further analysis, a multivariate analysis of covariance (MANCOVA) was used to examine whether healthcare workers' hand-hygiene practices before, during, and after were different while controlling for their gender, department, and hospital type. I found that no statistically significant differences were found when observing the healthcare workers behaviors of hand-hygiene practices. However, when using the self-reported questionnaire data, I found that nurses and females reported better… Advisors/Committee Members: O'Rourke, Mary Kay (advisor), Reynolds, Kelly A.

▼ Occupational exposures to hand-arm vibration and dust have been shown to have deleterious human health effects. Exposure to vibration from pneumatic tools can result in Hand-arm Vibration Syndrome (HAVS), which is a collection of vascular, sensorineural, and musculoskeletal disorders. Exposure to dust can result in a variety of adverse respiratory symptoms. The use of a low-frequency, high-magnitude sand rammer tool during mold-making processes at a foundry could result in significant exposure to these hazards, thus it is important to mitigate the associated risks in order to ensure worker safety. The goal of this study was to evaluate whether different pneumatic pressure levels and sand rammer types have an effect on reducing hand-arm vibration and dust exposures at a foundry. Vibration and dust measurements were obtained at three different pneumatic pressure levels (90 psi, 80 psi, 70 psi) and for three different sand rammer types (LM, SM, T). The primary concern of the study was reducing hand-arm vibration exposure. Measurements were taken in compliance with ISO 5349-1 resulting in frequency-weighted, root-mean-square (rms) acceleration values (m/s2). Significant differences in mean rms acceleration were observed across all pneumatic pressure levels and sand rammer types. At 90 psi the mean rms acceleration value was 25.53 m/s2, decreasing to 19.58 m/s2 at 80 psi, and further decreasing to 18.38 m/s2 at 70 psi. The mean rms acceleration values were 19.63 m/s2 for sand rammer LM, 21.46 m/s2 for SM, and 19.95 m/s2 for T. The results of this study indicate that reducing pneumatic pressure levels can reduce vibration exposure in the workplace when using low-frequency, high-magnitude tools. The results also indicate that the use of different sand rammer types produces differences in vibration exposure when tested across all pneumatic pressure levels. Dust measurements were taken concurrently with vibration measurements. The number of dust particles was counted for each pneumatic pressure level and sand rammer type. Overall, the mean particle count for the dust measurements was the highest at 90 psi (41,681) followed by 70 psi (33,514), and 80 psi (26,047). Sand rammer SM had the highest mean dust particle count at 35,732, followed by T at 34,460, and LM at 31, 382. The results indicate that lowering pneumatic pressure levels could potentially reduce dust exposure in the workplace when using a percussive tool such as a sand rammer. However, variability in the sampling conditions related to dust measurements weaken the association.

▼ The accumulation of oxidative DNA damage has been hypothesized as a key event in chemical carcinogenesis. In this study, oxidative DNA damage was evaluated in the livers of rats exposed to vinyl chloride (VC), 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD), 3,3',4,4',5-pentachlorobiphenyl (PCB 126), 2,3,4,7,8-pentachlorodibenzofuran (PeCDF) and 2,2',4,4',5,5'-Hexachlorobiphenyl (PCB153). Eight oxidative DNA adducts were measured, 8-hydroxyl-2'-deoxyguanosine (8-OHdG), 1, N⁶-etheno-2'-deoxyadenosine (ϵdA), N², 3-ϵG, 1, N²-etheno-2'-deoxyguanosine (1, N²-ϵdG), 3-(2'-deoxy-β-d-erythro-pentofuranosyl) pyrimido[1,2-α]purin-10(3H) (M₁dG), acrolein, crotonaldehyde and 4-HNE-derived dG adducts (assigned as AcrdG, CrdG, and 4-HNEdG respectively). ϵdA is one of the promutagenic DNA adducts formed by VC, which can also be formed by lipid peroxidation. In this study, both adult and weanling Sprague-Dawley rats were exposed to 1100 ppm (¹³C₂)-VC for 1 week (6 h/day, 5 days/week). The results indicated that NA-ϵdA concentration did not show significant difference in the liver of adult and weanling rats after VC exposure. The distribution pattern of (¹³C₂)-ϵdA in liver, lung and kidney indicated that liver was the dominant target organ for VC toxicity in both adult and weanling rats. ROS-induced DNA adducts were detected in the liver of female intact, ovariectomized (OVX) and male Sprague-Dawley rats, including 8-OHdG, 1, N⁶-ϵdA, AcrdG, and CrdG. These animals were exposed to TCDD for 30 weeks after diethylnitrosamine (DEN) initiation. Induction of these adducts was consistently found in liver DNA of TCDD-treated intact female rats and 17β-estradiol (E₂) supplemented OVX female rats, but not detected in OVX rats without E₂ supplement or male rats. These results further confirmed that the induction of these adducts occurs via a sex-specific and estrogen-dependent mechanism reported previously. Oxidative DNA damage was measured in liver DNA of female Sprague-Dawley rats following 53-week exposure of PHAHs, including PCB153, PCB126, TCDD, and the ternary mixture of TCDD, PCB126 and PeCDF. Increases of 8-OHdG, N², 3-ϵG and 1, N⁶-ϵdA were observed in PCB153 or PCB126 exposed animals. Significant increases of 1, N⁶-ϵdA were observed in all animals exposed to TCDD and the ternary mixture. Increases of 1, N²-ϵdG, CrdG, AcrdG, 4-HNEdG and M1dG were detected in animals exposed to the ternary mixture, but not the TCDD treated rats compared to the control.

▼ Background: Asthma is a growing epidemic in the U.S. Obesity, and more recently metabolic syndrome, has been shown to be associated with increased prevalence of asthma morbidity prevalence. Air pollution exposure, meanwhile, is associated with increased risk of acute asthma exacerbation. However, it is unclear the extent to which co-morbidities, specifically obesity and metabolic syndrome, increase the risk of air pollution related asthma morbidity. Methods: Data for 105,914 unscheduled asthma hospital admissions with a primary diagnosis of asthma in New York City (NYC) during 2003–2006, were obtained from the New York State Department of Health Statewide Planning and Research Cooperative Survey. Daily monitored pollutant concentrations from NYC-area monitors were averaged to determine daily exposure estimates for pollutants, including fine particulate matter (PM_2.5), nitrogen dioxide (NO₂), sulfur dioxide (SO₂), and ozone (O₃). A Poisson, generalized linear model was utilized to assess the association of these acute air pollution exposures with daily asthma hospital admissions among children (ages 1–17), adults (ages 18–64), and older adults (ages 65 and older). Analyses stratified by secondary diagnoses were then performed to determine whether obesity or metabolic syndrome co-morbid conditions modified the associations of air pollution and asthma hospital admissions in these age subpopulations. Results: Asthma hospital admissions among children, adults, and older adults were significantly associated with acute air pollutant exposures. Children with obesity had significantly higher risk ratios for asthma hospital admissions vs. children without obesity for associations with PM_2.5 and NO₂, especially among girls with obesity and during the warm season of the year. While the individual co-morbidities corresponding to metabolic syndrome (i.e., hypertension, diabetes, obesity, and hyperlipidemia) were not observed to significantly modify the associations of air pollutants and asthma hospital admissions, adults and older adults with multiple secondary diagnoses corresponding to metabolic syndrome had significantly higher risk ratios for asthma hospital admissions vs. those without metabolic syndrome. Conclusions: Obesity in children, and metabolic syndrome in adults, significantly increased the risk of air pollution related asthma hospital admissions in NYC. This information may enhance the consideration of susceptibility to air pollution in government policymaking, as well as inform physicians advising at-risk patients.

A research gap in the fields of exposure assessment and toxicology that remains unaddressed is the assimilation of experimental conditions to those of the real world human exposure. Currently, there is a lack of understanding of the properties of particles released by nano-enabled products (NEPs). Thus, we designed a multi-tiered methodology to physico-chemically, morphologically and toxicologically characterize engineered nanomaterials (ENMs) released from NEPs (i.e., toner powder). It is well established that printers emit nanoparticles during their operation; however, the physico-chemical and toxicological characterization of real world printer-emitted nanoparticles (PEPs) remains incomplete, hampering proper risk assessment efforts. For example, a number of studies estimating the potential adverse effects of PEPs used bulk toner particles as test particles rather than the actual particulate matter released by laser printers. Thus, the public health implications of exposure to PEPs remain largely unknown. For this project, a printer exposure generation system suitable for the subsequent physico-chemical, morphological, and toxicological characterization of PEPs was developed and used to assess the properties of particulate matter released from the use of commercially available laser printers. The system consists of a glovebox type environmental chamber for uninterrupted printer operation, real-time and time-integrated particle sampling instrumentation for size fractionation and sampling of PEPs and an exposure chamber for inhalation toxicological studies. Results from our extensive analysis show that laser printers emit up to 1,300,000 particles/cm3, most of which are nanoparticles. Further, we confirmed that a number of ENMs incorporated into toner formulations (e.g., silica, alumina, titania, ceria,) become airborne during printing. Both in vitro and in vivo toxicological evaluation showed PEPs are biologically reactive and may cause significant cytotoxicity, membrane integrity damage, reactive oxygen species production, pro-inflammatory cytokine release, angiogenesis, cytoskeletal and epigenetic changes as well as lung inflammation. This work highlights the importance of understanding life-cycle nano environmental health and safety implications of NEPs and assessing real world exposures and their associated toxicological properties rather than focusing on ‘‘raw’’ materials used in the synthesis of an NEP. Such analysis can be achieved for pollutants emitted by any NEP by employing the multi-tiered methodology described in this dissertation.

▼ This dissertation examines whether spatial measures of health determinants and health outcomes are being used appropriately and effectively to improve the health of marginalized populations in the United States. I concentrate on three spatial measures that have received significant policy and regulatory attention in California and nationally: access to healthful foods, climate change, and housing quality. I find that measures of these health determinants have both significant limitations and unrealized potential for addressing health disparities and promoting health equity. I define spatial triage as a process of using spatial data to screen or select place-based communities for targeted investments, policy action, and/or regulatory attention. Chapter 1 describes the historical context of spatial triage and how it relates to ongoing health equity research and policy. In Chapter 2, I evaluate spatial measures of community nutrition environments by comparing data from in-person store surveys against data from a commercial database. I find that stores in neighborhoods with higher population density or higher percentage of people of color have lower availability of healthful foods and that inaccuracies in commercial databases may produce biased measures of healthful food availability. Chapter 3 focuses on spatial measures of climate change vulnerability. I find that currently used spatial measures of "disadvantaged communities" ignore many important factors, such as community assets, region-specific risks, and occupation-based hazards that contribute to place-based vulnerability. I draw from examples of successful actions by community-based environmental justice organizations and reframe "disadvantaged" communities as sites of solutions where innovative programs are being used to simultaneously address climate mitigation, adaptation, and equity goals. In Chapter 4, I combine electronic health records, public housing locations, and census data to evaluate patterns of healthcare utilization and health outcomes for low-income children in San Francisco. I find that children who live in redeveloped public housing are less likely to have more than one acute care hospital visit within a year than children who live in older, traditional public housing. These results demonstrate how integrating patient-level data across hospitals and with data from other sectors can identify new types of place-based health disparities. Chapter 5 details recommendations for analytic, participatory, and cross-sector approaches to guide the development and implementation of more effective health equity research and policy.

The widespread use of engineered nanomaterials (ENMs) in consumer products inevitably raises concern for potential exposure to ENMs released from such nano-enabled products (NEPs). It is therefore important to understand the scenarios and mechanisms by which ENMs are released over the NEP lifecycle causing exposure and potential environmental health implications. In this dissertation, I focus on understanding the fundamentals related to the incineration/thermal decomposition of industrially relevant NEPs, such as thermoplastics and coatings, widely used in many applications. The potential release of ENMs (used as nanofillers in NEPs) into the environment and the physicochemical, morphological (PCM) and toxicological properties of the released byproducts (released aerosol, residual ash and off-gases) are assessed. The role of NEP matrix composition, nanofiller type/size/mass-loading and thermal process conditions on the thermal decomposition behavior, release dynamics and byproduct PCM properties is investigated in detail. The potential cellular toxicological implications of the released aerosol are assessed and linked to PCM properties of the NEPs. Key findings suggest that inorganic (and catalytic) metal oxide nanofillers such as TiO2, Fe2O3 and CuO are more likely to be released into the aerosol compared to carbonaceous nanofillers (e.g., CNTs (carbon nanotubes)) and inert metalloid oxide nanofillers (e.g., SiO2). Moreover, majority of inorganic nanofillers are retained loosely in the residual ash as flaky clusters, prompting the concern for their subsequent release into the environment (due to weathering, leaching, etc.), whereas CNTs are completely combusted at the high temperatures (>800 °C). More importantly, in the case of released catalytic metal oxide nanofillers, due to their synergistic interactions with gaseous semi-volatile organic byproducts, carcinogenic polycyclic aromatic hydrocarbons (PAHs) could be formed and thus present a significant inhalation exposure hazard for incineration facility operators, firefighters and surrounding community. Furthermore, increased bioactivity and toxicity of the released aerosol compared to the control (no nanofiller) are also confirmed in cellular studies. Future studies should investigate effects of sequential lifecycle stresses such as weathering on thermal decomposition of NEPs. Additionally, environmental fate and transport of ENMs from residual ash should be performed to assess potential environmental health risks and develop mitigation strategies associated with incineration/thermal decomposition of NEPs.

▼ The knowledge of high-pressure phase behavior and phase equilibria of polyethylene (PE) in hydrocarbon solutions is an integral part of the process design and manufacturing of PE via solution polymerization. This thesis focuses on the study of fundamental polymer thermodynamics and key mechanisms that govern phase stability in polyolefin solutions via combined thermodynamics-molecular modeling algorithms.Force field-molecular dynamics simulations are utilized to bridge the gap between experimentally observed macro-scale phase separation phenomena and molecular-level details of fundamental studies of macromolecular thermodynamics in polymer-solvent systems. In this context, the main contributions of the present thesis work focus on molecular thermodynamic characterization of the pressure-induced phase separation (PIPS) mechanism and lower critical solution temperature (LCST) fluid phase behavior of PE solution; high-pressure thermodynamic and structural properties of binary and ternary solutions of PE + hexane and PE + hexane + ethylene, respectively; improvement of the computational efficiency and accuracy of the isobaric-isothermal and canonical ensemble simulations; overcoming the practical challenges involved in the implementation of equation of state theories.A fully-atomistic molecular mechanics force field combined with molecular dynamics is implemented to compute solubility parameter, liquid phase density, structure, and internal pressure of HDPE and hexane over a broad range of pressures. Based upon the knowledge of pressure and temperature dependence of solubility parameters the binary interaction parameter is computed to shed light on phase stability predictions in PIPS mechanism and LCST phase behavior. A molecular-level explanation for the change in cohesive properties and structure of PE and hexane upon raising the external pressure is provided. Additionally, a relation is established between cohesive energy density and internal pressure for the solvent and polymer as a function of pressure. A comparison is reported between electrostatic algorithms of switch function and the particle mesh Ewald method, and also the effect of grid spacing on the computational accuracy of electrostatic energy contribution is revealed.This thesis also implements the state of the art molecular modeling methods and equation of state modeling to report on the pressure dependence of binary PE solution density for various polymer compositions, required to solve the phase equilibria and kinetics of compressible polymer solutions. The effect of the cut-off radius of intermolecular potentials on the non-bonded forces and densities of the polymer-solvent mixture with the objective of improving the computational efficiency of molecular dynamics simulations is investigated and an optimized cut-off distance is suggested for high-pressure molecular mechanics modeling of compressible polyolefin solutions. An atomistic-level analysis of the impact of pressure on the structure of PE-solvent mixture is also provided.The isobaric-isothermal… Advisors/Committee Members: Alejandro D Rey (Supervisor).

▼ Deux projets de recherche ont été menés afin de déterminer le potentiel du millet perlé fourragé pour la nutrition des vaches laitières. Pour l'étude 1 nous avons évalué les effets de remplacer l'ensilage de maïs (CS; contrôle) par 2 cultivars de millet [c.-à-d., le millet régulier (RM) et le millet sucré (SM)] dans l'alimentation des vaches; alors que pour l'étude 2 nous avons évalué 2 différents stades de maturité du millet sucré [c.-à-d., stade gonflement (EM) ainsi que stade pâteux au stade mature (MM)] en les comparant à l'ensilage de graminée (GS; contrôle). Les paramètres évalués dans les deux études étaient la production laitière, la digestibilité totale et les caractéristiques de fermentation ruminale. Les deux expériences ont utilisé 15 vaches en lactation dans un 3 x 3 carré Latin répliqué. Les vaches ont été nourris des rations totales mélangées avec un ratio fourrages : concentrés (F:C) élevé (c.-à-d., 68:32 et 60:40, respectivement). Trois vaches ruminalement fistulées ont été utilisées pour évaluer la fermentation ruminale et la digestibilité totale. L'étude 1 a démontré que les vaches consommant CS ont ingéré plus de matière sèche (MS; 24,4 vs. 22,7 kg/j) et d'amidon (5,7 vs. 3,7 kg/j), mais moins de fibre a détergent neutre (NDF; 7,9 vs. 8,7 kg/j) que les vaches consommant RM ou SM. Par contre, l'ingestion de MS, d'amidon et de NDF n'ont pas été affectées par les types d'ensilage de millet. En alimentant les vaches avec CS par rapport à RM cela à augmenté le rendement en lait (35.2 vs. 32.7 kg/j), l'énergie du lait corrigée (ELC; 38.0 vs. 35.8 kg/j) et les solides du lait corrigé (SLC; 35.3 vs. 32.7 kg/j). Cependant, les rendements en lait, ELC et SLC des vaches nourries avec SM étaient semblables à celles nourries avec CS et RM. La concentration en protéines du lait était plus élevée pour les vaches consommant CS, intermédiaire pour les vaches consommant SM et plus basse pour les vaches consommant RM. La concentration en solides de lait sans gras (SSG) était moins élevé, alors que l'urée d'en le lait (MUN) était plus élevé pour les vaches nourries avec RM que celles nourries avec CS.. Le pH du rumen et le niveau NH3-N du rumen étaient plus élevé pour les vaches consommant RM et SM que pour les vaches consommant CS. La digestibilité totale de MS, NDF, protéine brute (PB) et d'énergie brute n'ont pas été influencés par les traitements alimentaires. Dans l'étude 2, les vaches soignées avec GS comparativement à celles soignées avec MM ont consommé plus de MS (22,9 vs. 21,7 kg/j) et de PB (3,3 vs. 3,1 kg/j), mais une quantité similaire d'amidon (4,9 kg/j) et de NDF (1,3 kg/j). Par contre, la maturité avancée du millet sucré (EM vs. MM) n'a pas affecté l'ingestion de MS, NDF et PB. Mais, par rapport à GS, MM a réduit le rendement en lait (29,1 vs. 26,1 kg/j), ELC (30,4 vs. 28,0 kg/j) et SLC (28,3 vs. 26,4 kg/j). Cependant, les rendements en lait, ELC et en gras corrigé du lait étaient similaires entre les vaches nourries avec EM et GS.

▼ Dans cette étude, le rejet et la présence des PhACs dans l'environnement sont considérés depuis deux perspectives différentes. D'abord, une perspective amont depuis laquelle la concentration des PhACs dans l'environnement est estimée grâce à leur degré d'utilisation ou d'excrétion. Cela permet d'évaluer les inquiétudes liées à l'éco-toxicologie et/ou la santé humaine. Quatre évaluations uniques en leur genre ont été menées depuis cette perspective. La première évaluation a débouché sur le développement d'un modèle informatique du rejet endogène d'androgènes, d'hormones thyroïdiennes et leurs métabolites in vivo dans l'environnement. Le modèle a été utilisé pour évaluer la pertinence de tels polluants d'un point de vue éco-toxicologique; ainsi, il a été mis en évidence que le rejet endogène d'androstènedione comporte un risque d'impacts mesurables sur les poissons dans le cadre d'un scénario de forte exposition. La deuxième évaluation a conduit au développement d'une approche pour l'évaluation des risques liés à la santé humaine et à l'éco-toxicologie posés par les PhACs présents dans l'urine épandue sur les terres agricoles. Cette approche a été appliquée pour évaluer au travers de six voies d'exposition 25 PhACs abondamment utilisés. De ces 25 PhACs, 14 pourraient poser des risques d'éco-toxicologie ou pour la santé humaine. La troisième évaluation portait sur l'analyse des sources et la pertinence en termes de risques pour la santé humaine du rejet aquatique de 335 PhACs dans l'environnement au Canada. L'évaluation suggère qu'un maximum de sept sources distinctes peut mener au rejet dans l'eau d'un PhAC donné, avec l'importance de chaque source variant de manière significative d'un cas à l'autre. Les PhACs sont principalement rejetés dans l'environnement à travers leur utilisation au sein des populations; mais parfois, les hôpitaux entre autres sources peuvent aussi être d'importants contributeurs. L'évaluation de la pertinence de l'analyse de la présence potentielle de ces 335 PhACs dans les eaux potables montre que 323 de ces PhACs devraient poser un risque négligeable pour la santé humaine. Cependant, 14 PhACs méritent de plus amples recherches selon les résultats. De plus, il a été démontré que la surveillance environnementale des PhACs est actuellement insuffisante pour évaluer de façon correcte leurs impacts éco-toxicologiques et sur la santé humaine. Dans la quatrième évaluation, une approche a été développée pour mieux comprendre et évaluer les relations et compromis nécessaires entre les choix de contraception d'une population et la concentration en estrogènes stéroïdiens dans l'environnement. De façon contre-intuitive, l'analyse a suggéré que quelle que soit l'option de contraception utilisée, qu'elle soit à base d'estrogènes ou purement un instrument physique, des rejets d'estrogènes stéroïdiens dans l'environnement sont évités. Les femmes qui utilisent des contraceptifs oraux à base d'éthinylestradiol produisent une moindre concentration en estrogènes dans l'environnement que celles qui abandonnent… Advisors/Committee Members: Jim A Nicell (Supervisor).

A fraction of subsurface drained corn-soybean field has been converted to grassland in the Midwestern US prairies under the Conservation Reserve Program. This conversion has significantly improved environmental quality but may have altered the local hydrological cycle. Soil water, drainage, and evapotranspiration are very important factors in hydrological processes. Simulating these factors is essential to addressing hydrological processes appropriately. The Great Plains Framework for Agricultural Resource Management in Rangelands (GPFARM-Range) model is one of the recently developed rangeland management tools. The objectives of this paper are (1) to investigate the performance of GPFRAM-Range model in simulating soil moisture in prairie subsurface drained fields; and (2) to investigate the performance of GPFARM-Range model when using water flux to mimic drainage discharge rate. The data on soil water content, drainage, and crop biomass were collected at a subsurface drained prairie near Gilmore City, Iowa. This research compared simulated soil water content for four soil layers and total soil water storage with observed data. This research indicated that GPFARM-Range model was sufficient to simulate either soil moisture or subsurface drainage flow. When model simulated the soil moisture well (with percent bias (PBIAS) 5.1% and 1%, Nash-Sutcliffe model efficiency (NSE) 0.67 and 0.56 for calibration years and validation years, respectively), it can only simulate the subsurface drainage with PBIAS of -18.32% and NSE of 0.26, while keeping the subsurface drainage well (with four-year simulated water flux of 37.1 cm compared with observed four-year water flux of 37.0 cm), it can only simulate the soil moisture with NSE of 0.65 and 0.47 for calibration years and validation years, respectively. In scenario 1, which GPFARM-Range model simulated better on drainage than soil moisture, the evapotranspiration for perennial grasses were mostly higher (42.8 cm for 2006, 47.8 cm for 2007, 45.8 cm for 2008 and 44.8 for 2009) than corn in odd years and soybean in even years (41.7 cm for 2006, 49.9 cm for 2007, 40.2 cm for 2008 and 43.6 cm for 2009) except for 2007. For the other sites that planted soybean in odd years and corn in even years, the evapotranspiration for perennial grasses were higher in 2007 (47.1 cm compared with 47.8 cm) and 2009 (41.8 cm compared with 44.8 cm). The corn and soybean sites were planted from the same field at the same time. For the scenario 2, which GPFARM-Range model simulated better on soil moisture than subsurface drainage rate, the evapotranspiration for pasture land were relatively higher than scenario 1, which were 45.4 cm for 2006, 53.5 cm for 2007, 52.6 cm for 2008 and 50.6 cm for 2009. This study also demonstrated that it was not sufficient to mimic subsurface drainage using water flux from the last soil layer, which might due to the time lag.

▼ Le vif intérêt que suscitent actuellement les mécanismes de "Paiements pour les services écosystèmiques" (PSE) pour la gestion des ressources naturelles est supporté par une argumentation fondamentalement économique sur laquelle l’importance accordée à l’efficacité supplante les politiques de préservation et les initiatives communautaires pour la conservation de la nature, car ces dernières manquent d’obligations conditionnelles à l’entretien de la terre. La logique économique qui sous-tend les PSE se réfère à l’internalisation des coûts sociaux liés à la détérioration des ressources naturelles. Les services écosystèmiques étant de nouveaux produits produits (ou objets d’échange) à l’échelle du marché incarnent de meilleures déterminants dans la prise de décisions. La présente recherche propose une analyse conceptuelle critique et empirique dans le cadre des PSE fondés sur les principes du marché afin d’avancer la gestion de l’eau intégrée et adaptée. La complexité des caractéristiques économiques, spatiales et temporelles des services économiques de même que les valeurs diverses souvent conflictuelles, pousse la recherche actuelle à reconnaître les jeux de pouvoirs définissant la base des PSE en tant qu’instrument économique. Un cadre conceptuel est développé pour démontrer le décalage existant entre la caractérisation des services écosystèmiques en tant que biens économiques et leurs traitements dans le contexte des PSE comme produit d’échange. Deux études empiriques ont été effectuées basées sur un projet de PSE prévoyait à la Vallée de Katmandou au Népal. La première de ces études illustre le revers de l’application des instruments économiques en ciblant l’optimisation des paiements dans une logique de marché, car via une vision divisant la nature et la société, ces instruments faillissent à atteindre les institutions sociales et les valeurs. La deuxième étude utilise l’évaluation sociale multicritère comme approche délibérant pour conceptualiser des incitatifs à la gestion des ressources naturelles à travers un processus de négociations ouvert à la communication des valeurs, priorités et opportunités pour l’amélioration due bien-être collectif et individuel. Cette évaluation ne permet pas la compensation d’un groupe par l’usage d’une valeur, mais incite plutôt la réalisation des échanges nécessaires à l’élaboration d’un compromis entre les perspectives des groupes impliqués. La dernière étude empirique à été réalisé sur un site pour une étude de cas pilote d’implantation des PSE à un bassin versant au Kirghizstan. Le but de cette étude est d’investiguer les aspects comportementaux de l’intérêt personnel-rationnel motivant la participation des individus à s’inscrire à un projet de PSE. Cette étude exploratoire à démontré la prépondérance accordée à l’intérêt personnel-rationnel par rapport aux règles sociales collectives, ce qui peut produire des résultats non-désirés en fonction du contexte, de l’encadrement et des normes sociales déjà en place dans le lieu d’implantation. Les implications de cette recherche… Advisors/Committee Members: Jan Adamowski (Supervisor1), Nicolas Kosoy (Supervisor2).

Une révision Néarctique et une analyse phylogénique des espèces mondiales du genre Callomyia Meigen (Diptère: Platypezidae) ont été entrepris. Dix espèces sont reconnues dans la région du Néarctique (C. argentea Cumming sp. nov., C. arnaudi Cumming sp. nov., C. bertae Kessel, C. browni Cumming sp. nov., C. calla Kessel, C. corvina Kessel, C. gilloglyorum Kessel, C. proxima Johnson, C. velutina Johnson, et C. venusta Snow), dont trois nouvelles espèces et trois nouveaux synonymes. La délimitation des espèces est principalement basée sur des données morphologiques. Toutefois, des données de séquences moléculaires (codes-barres d’ADN) ont été utilisés, lorsque possible, afin d’aider à séparer les espèces et à associer les sexes. Des descriptions d’espèces, diagnostiques, ainsi que des illustrations de leurs distributions géographiques, des espèces à part entière, des parties génitale des mâles et des caractères diagnostiques additionnels important sont présentées. Une clé d’identification des espèces Néarctiques pour chaque sexe est aussi fournit. L’analyse phylogénétique incluant 32 caractères morphologiques, 28 caractères pour le stade adulte et quatre pour le stade larvaire, supporte la monophile de Callomyia. Cette analyse révèle d’ailleurs que les espèces Néarctique ne forment pas un group monophylétique. Elles sont plutôt distribuées en au moins trois clades important. Des relations rapprochées entre quelques espèces Néarctique et Paléarctique ont été trouvé, mais aucune espèce Holarctique n’a été découverte.

A Nearctic revision and phylogenetic analysis of the world species of the genus Callomyia Meigen (Diptera: Platypezidae) was undertaken. A total of ten species are recognized from the Nearctic Region (C. argentea Cumming sp. nov., C. arnaudi Cumming sp. nov., C. bertae Kessel, C. browni Cumming sp. nov., C. calla Kessel, C. corvina Kessel, C. gilloglyorum Kessel, C. proxima Johnson, C. velutina Johnson, and C. venusta Snow), including three new species and three new synonyms. Delimitation of species was based primarily on morphological data, however, molecular sequence data (DNA barcodes) were used wherever possible to help determine species boundaries and associate sexes. Species descriptions, diagnoses, and illustrations of distributions, habitus, male terminalia and additional important diagnostic characters are presented. A key to the Nearctic species for both sexes is also provided. The phylogenetic analysis used 32 morphological characters, 28 adult and four larval characters, and supported the monophyly of Callomyia. It also revealed that the Nearctic species do not form a monophyletic group and are distributed within at least three major clades. Close relationships were found between some of the Nearctic and Palaearctic species, but no Holarctic species were discovered.

The welfare state continues to be eroded in the Global North. In Canada and the U.S., food banks are now one of the only systems of relief available. But in both countries, critics have accused food banks of being apolitical and thus taking away government responsibility to address inequality. The rise of food banks has been linked to the decline of the welfare state, leading to an assumption that an increase in public assistance can end the need for food banks. Yet little research exists that examines how other institutions such as the food industry drove food bank growth, or how food banks are politically active. The history of food banks in Canada presents an informative case study because the state was not directly involved in establishing food banks, thus allowing greater insight into the role of industry in the institutionalization of food banks and their political activity. Using environmental institutions and political ecology frameworks we conducted a literature review and interviews of experts, as well as a case study of one food bank. Our findings suggest that the factors leading to the existence of food banks cannot only be linked to cuts in welfare; rather, the influence of industrial decline and centralization of the food industry must also be taken into account, as well as social movements and the policy gap around food waste. Food banks can be political, using available resources as ‘fuel’ to challenge government failure. The case of Canadian food banks indicates that, to address inequality and food insecurity in the Global North, researchers and policy-makers should not only focus on welfare but need to tackle the cost-shifting practices of the food industry and work toward joined-up and nested food policy institutions. Further, food banks, or organizations that look like them, can help address rising food insecurity if they are provided with sufficient legal, political, and financial support.

L'État-providence continue de s’éroder dans le Nord global. Au Canada et aux États-Unis, les banques alimentaires constituent aujourd’hui un des seuls systèmes d’aide disponibles. Mais dans les deux pays, les critiques accusent les banques alimentaires d’être apolitiques et, par cela, d’atténuer la responsabilité des gouvernements d’aborder l’inégalité. a prolifération des banques alimentaires a été reliée au déclin de l’État-providence, ce qui laisse supposer que l’accroissement de l’aide publique pourrait éliminer le besoin des banques alimentaires. Pourtant, il existe peu de recherches qui examinent le rôle des autres institutions – telles que l’industrie alimentaire – dans la croissance des banques alimentaires, ou les activités politiques de celles-ci. ’histoire des banques alimentaires au Canada forme une étude de cas informative : l’État n’a pas joué de rôle direct dans l’établissement des banques alimentaires, ce qui permet un meilleur aperçu du rôle de l’industrie dans l’institutionnalisation des banques alimentaires, et de leur activité politique.

Les solutions institutionnelles peuvent permettre à la société de répondre collectivement de bon nombre de ses défis environnementaux plus urgents. Une solution institutionnelle, gouvernance collaborative, dépend de la participation volontaire des intervenants non-étatiques. Cependant, les sources de légitimité pour les nouveaux institutions telles que la gouvernance collaborative restent floues, tandis que la façon dont la légitimité pourrait être amélioré est mal comprise. La prémisse de cette thèse est que la légitimité, à partir d'un interprétation sociologique, est une caractéristique fondamentale des institutions qui doit être compris dans son contexte, mais peut également être mis en forme par l'agence de personnes. L'objectif de cette thèse est double: Il est le premier à comprendre la gouvernance collaborative de l'eau au Québec, Canada, et deuxième pour évaluer ce qui a été fait et ce qui plus peut être fait pour l'améliorer. Tout d'abord, gouvernance collaborative de l'eau au Québec est évaluée par la lentille de la légitimité, conformément aux perspectives des intervenants locaux, des employés de l'organisme, et des décideurs politiques provinciaux, utilisant les données recueillies dans 36 entrevues en personne. Les résultats démontrent la nécessité d'améliorer l'ajustement entre les institutions collaborative et les institutions représentatives existantes, d'améliorer leur nature complémentaire tout en répondant aux préoccupations de fond, et de résoudre les différences de points de vue entre les intervenants dans les bassins versants et les décideurs provinciaux. Deuxièmement, les données d'entrevues avec un total de 13 employés et des individus clés (les agents) de six organismes de bassins versants au Québec sont utilisés pour explorer comment ces agents ont façonné des processus de collaboration pour répondre à des déficits de légitimité. Les stratégies des agents et de leurs justifications ont été identifiées, donnant un aperçu de la façon dont les agents adaptés gouvernance collaborative de l'eau aux différents contextes, en dépit des limites à la conception institutionnelle. Cependant, tandis que les agents ont contribué à faire de gouvernance collaborative de l'eau légitime et efficace au niveau des bassins versants, des changements structurels étaient souvent au-delà de leurs capacités. Informé par les résultats de ces deux enquêtes, des recommandations pour améliorer la Politique nationale de l'eau et sa mise en œuvre de la gouvernance collaborative de l'eau en sont proposés. De cette manière, une interprétation sociologique de légitimité, jumelée avec une compréhension agentique de changement institutionnel, peut être utilisée pour comprendre et améliorer les institutions de gouvernance environnementale complexes.

Institutional solutions can enable society to collectively address many of its most pressing environmental challenges. One institutional solution, collaborative governance, relies on the voluntary involvement of non-state stakeholders. However, the sources of legitimacy for novel…

▼ La perte des milieux humides continue d'être parmi les moteurs des changements environnementaux globaux, et, malgré la panoplie de recherches conduites sur l'état de ces écosystèmes, leur condition écologique ne semble pas s'améliorer. La dégradation de zones humides est surtout causée par des activités humaines alignées avec la création et augmentation des profits, résultant dans un mépris généralisé envers les propriétés complexes des milieux humides. Par conséquent, ce mémoire de maîtrise vise à analyser le milieu humide Upo d'un point de vue de politiques de gestion qui inclut les conséquences socio-écologiques de la complexité des milieux humides. Le cadre théorique choisi se base sur une revue de la littérature générale et de celle de la gestion des politiques. D'abord, j'identifie le cadre théorique pour l'analyse des politiques qui inclue la complexité écologique, économique et institutionnelle des milieux humides. En ce qui concerne la complexité écologique, j'introduis et je considère les difficultés à comprendre explicitement la nature des milieux humides. Pour expliquer la complexité économique, j'aborde les problèmes de compréhension théoriques présents dans la gestion de la complexité des milieux humides basée sur le paradigme économique actuel. Le problème fondamental de ce system économique provient du rejet de sa propre dépendance et subordination envers les écosystèmes, et de la tendance à se limiter aux méthodes de valorisation monétaire lorsqu'il s'agit de protéger la nature. Les effets socio-écologiques des institutions dans ces zones humides, qui incluent «command and control», la gestion communautaire, et les institutions axées sur le marché, sont analysés, ainsi que leur efficacité dans la réduction de la dégradation de ces écosystèmes à différentes échelles. En se basant sur ces trois dimensions des écosystèmes humides, la complexité écologique du milieu humide Upo démontre la présence d'une compréhension limitée de la portée et de la durée des fonctions écologiques de zones humides. Bien que le milieu humide Upo soit inextricablement connecté à d'autres zones humides en Corée (Mokpo, Sajipo, et Jokjibul), il répercute aussi sur d'autres environnements, comme le ruisseau de Topyeong et la rivière Nakdong. La complexité économique du milieu humide de Upo est susceptible d'aggraver les obstacles en gestion, malgré la provision de la part de ces écosystèmes d'un grand nombre de bénéfices comme la régulation de services écosystémiques, SE, (régulation des inondations et purification d'eau), la stabilisation de ces services (soutien de fonctions d'habitat), l'approvisionnement des SE (approvisionnement d'eau) et présence de SE culturels (le Pavillon du milieu humide Upo). Cependant, le gouvernement local du comté de Changnyeong favorise surtout des politiques de développement industriel qui considèrent que l'approvisionnement des services écosystémiques. La zone humide Upo fut désignée comme un site humide international Ramsar en 1998, et elle est régulée sous la Loi de la conservation… Advisors/Committee Members: Nicolas Kosoy (Internal/Supervisor).

▼ La gestion durable du phosphore (P) représente une préoccupation importante tant à l'échelle mondiale que locale, car le P est un nutriment essentiel en agriculture et un important polluant aquatique. Bien qu'il y ait eu des progrès considérables dans notre compréhension des problèmes dans le cycle du P, liés à l'activité humaine, il reste encore d'importantes lacunes de connaissances qui doivent être comblées afin d'augmenter notre capacité à gérer efficacement cet élément clé. Par exemple, même si nous savons que les villes sont d'importants systèmes dans le mouvement du P, puisque s'y concentrent les flux entrants de P et les flux sortants, les connaissances sur la façon dont se déplace le P à l'intérieur et à travers les villes et le rôle que ces dernières peuvent jouer dans la gestion durable du P nous font défaut. L'importance des choix individuels, tels que les choix alimentaires dans la demande mondiale pour le P, reste incomprise. Dans la présente thèse, j'explore le rôle que les villes peuvent jouer dans l'amélioration de la gestion du P, particulièrement à travers les choix alimentaires et la pratique de l'agriculture urbaine. Je me penche sur la façon dont une approche interdisciplinaire intégrant les facteurs écologiques, sociaux et technologiques qui influencent les flux et la gestion du P urbain. Pour commencer, je me concentre sur le rôle des choix alimentaires humains dans la demande du P à travers le temps. J'examine de quelle façon les changements dans les régimes alimentaires ont modifié la demande de ressources de P au cours des 50 dernières années. Mes résultats indiquent que l'empreinte de P par habitant mondial (montant de P minéral nécessaire par personne pour la production alimentaire animale ou végétale qu'elle consomme) a augmenté de 38% de 1961 à 2007. Par la suite, j'examine une ville d'un pays avec une grande empreinte de P selon les choix alimentaires des citoyens (Montréal, Canada). J'ai quantifier le cycle du P dans le système alimentaire et dans le système de l'agriculture urbaine de la ville. J'ai déterminé que la plus grande partie du P entrant à Montréal s'accumule dans les sites d'enfouissement et que peu de P est en fait recyclé. En revanche, la majorité du P appliqué en agriculture urbaine provient de sources recyclées (comme le compost). Pour évaluer le potentiel de l'agriculture urbaine j'avais besoin de comprendre non seulement le cycle du P lui-même, mais aussi les facteurs sociaux, écologiques et technologiques qui influencent le cycle du P urbain. Pour développer un ensemble complet de facteurs sociaux, écologiques et technologiques qui pouvaient être examinés à Montréal, j'ai effectué une revue de la littérature exhaustive des études d'analyses de flux du P urbain. En utilisant la pensée systémique, j'ai trouvé huit catégories de facteurs qui devraient être inclus dans une analyse interdisciplinaire du cycle urbain du P. Finalement, je reviens à l'étude de cas de Montréal, pour examiner les facteurs qui influencent la gestion du P en détail. J'ai mené des entretiens… Advisors/Committee Members: Elena Bennett (Supervisor).

▼ Time-series and cohort studies of the effect of exposure to ambient air pollution on human health have been powerful tools in advancing our understanding in this area. The work presented in this thesis takes advantage of both time-series and cohort-study designs to estimate short-term and chronic health effects of exposure to PM_2.5 in a susceptible population across the United States. Chapter 2 presents an overview of the time-series and cohort studies approaches for estimating the relative risk of mortality from particulate air pollution and discusses the statistical issues and challenges inherent in these studies. The American Cancer Society study (ACS) (Pope et al., 1995) and the Harvard Six Cities study (SCS) (Dockery et al., 1993a) are landmark cohort studies for estimating the chronic effects of fine particulate matter (PM_2.5) on mortality. In Chapter 3, we estimate the chronic effects of PM2.5 on mortality for the period 2000-2002 using mortality data cohorts of Medicare participants and PM_2.5 levels from monitors in the same counties included in the SCS and the ACS. We estimate the mortality risk associated with air pollution adjusting for individual-level factors and area-level covariates. We propose that the Medicare files can be used to construct cohorts for tracking the risk of air pollution over time. In Chapter 4 we evaluate the transboundary health impact of a wildfire episode on a susceptible population of interest. The smoke plume generated from the forest fires in Quebec, Canada in July 2002 had major impacts on air quality across the east coast of the US. To evaluate the public health impact of smoke exposure on the elderly population in the US, hospital admission rates for cardiopulmonary causes were estimated in counties located in 11 states in the northeastern and mid-Atlantic region of the US, before and during the period of plume presence. We estimated significant associations between short-term increases in ambient PM_2.5 concentrations and hospitalizations for cardiorespiratory diseases within 11 of the affected states. This research adds to the growing body of literature demonstrating the significant impact of transboundary air pollution on the health of the elderly.

Poly- and Perfluoroalkyl Substances (PFASs) are a class of synthetic organic chemicals that have been in production since 1950s. They are detectable in virtually all Americans. Exposure to some PFASs have been linked to a suite of adverse health outcomes including developmental, metabolic and immunotoxic effects. Elucidating the origin of contamination and the relative importance of exposure pathways is critical for designing effective public health interventions to reduce exposure and prevent adverse health outcomes. Pathways for human exposure to these compounds include marine foods, drinking water and consumer goods. Several recent drinking water PFAS contamination has drown nationwide attention. This thesis links environmental sources and human exposure to understand the role of environment in the overall exposure and health risks related to PFASs. Chapter 1 of this thesis reviews the current science on PFAS sources, exposure pathways and health concerns. This introductory section leverages information from both peer-reviewed literature and regulatory docket files to present a comprehensive overview. Chapter 2 presents a spatial analysis on the latest nationwide drinking water PFAS occurrence data to establish the link between point sources and drinking water contamination. This work reveals the prevalence of drinking water PFAS contamination in the nation, and highlights the substantial data gap for a third of the country. Chapter 3 extends the link from drinking water to human plasma concentrations. By leveraging unique samples from a large U.S-based cohort study, Nurses’ Health Study, and applying both statistical and mechanistic models, I found that drinking water can be important exposure pathway even for the general population living far away from the point sources. I also quantified the relative importance of drinking water to overall human exposure, which has implications for current risk assessment practice and drinking water health advisory levels. Chapter 4 completes the loop around exposure source and human exposure by fingerprinting major exposure source based on the serum PFAS profiles. I identified effective tracers for exposure from marine foods and consumer products. I also discussed methodological considerations of using this approach. Chapter 5 summarizes all the work presented in this thesis and makes recommendations for future research. My thesis shows the increasing importance of environmental sources for PFAS exposure as these compounds are being phased out in consumer products. Risk assessment needs to incorporate temporal changes, interindividual variability and source information to be effective and health protective.

The objective of this dissertation is to contribute to ongoing research on prenatal metals exposure, in terms of arsenic, lead, and manganese, and infant health and growth, and to deepen the understanding of the complexity of such problems. We seek to do so in three parts. First we examine the association between combined prenatal metals exposure and infant birth weight and head circumference. Then, we look at the effect on birth weight from the HFE gene variants and its interaction effects with arsenic. Finally, we look at the association of prenatal metals exposure and child growth up to 36 months. The study populations of all three of our studies are taken from mothers enrolled in 2 hospitals affiliated with Dhaka Community Hospital in Bangladesh. They were given self-administered questionnaires at time of enrollment and are followed after birth. Child measurements were taken at time of birth, and the biomarker for these studies are cord blood metal measurements. In the first part of this dissertation, through multivariate linear regression, including a metal interaction term, we found that prenatal arsenic and manganese exposure individually associated with lowered birth weight and birth head circumference. We also found evidence of interactions between the two metals, suggesting that joint exposure creates greater deficit in birth outcomes. In the next part, looking at gene-environment interactions, we found significant modification effects of multiple SNPs on the HFE gene that increased the association between arsenic and birth weight. We also found direct effect of less studied HFE genes to lower birth weight. Finally, we assessed the effect of prenatal metals exposure on early growth in children through longitudinal analysis. In following the weight and height of the child from birth up to 36 months of age, our results indicated adverse association between arsenic and manganese on growth.

▼ Eastern Mediterranean (EM) region experience poor air quality because it is highly influenced by local and transported pollution. For this reason, we examined the particulate pollution in Cyprus, an EU-member country located in the EM region. First, we analyzed daily PM10 (particulate matter with aerodynamic diameter less than 10 μm) data collected in an urban and background site for sixteen years (1993-2008). We investigated long term trends using a Generalized Additive Model (GAM) after controlling for day of week, month, temperature, wind speed, and relative humidity. Annual PM10 (50.4-63.8 μg/m3) exceeded the 2005 EU annual standard (40 μg/m3) every year at the urban station, and dust storms were responsible for a small fraction of the daily exceedances. However, urban PM10 levels decreased from 59.4 μg/m3 in 1993 to 49.0 μg/m3 in 2008, probably in part as a result of traffic emission control policies. We then collected PM10 and PM2.5 samples (particulate matter with aerodynamic diameter less than 2.5 μm) in the four main cities in Cyprus using Harvard Impactors, during the year of 2012. We analyzed them for mass concentration and chemical composition, and conducted a source apportionment analysis. For PM2.5, seven source types were identified including regional sulfur (>30%), traffic emissions, biomass, re-suspended soil, oil combustion, road dust, and sea salt. For PM10-2.5 (coarse particles with aerodynamic diameter between 2.5 and 10 μm) three sources were identified, which include road dust, soil, and sea salt. Last, since the mortality effect estimates for PM2.5 components and mortality vary across studies and locations, we performed a meta-regression analysis to estimate their association using city specific estimates from time-series and case-crossover studies. We found significant associations between mortality and elements from combustion sources such as traffic, biomass burning, and oil combustion. Furthermore, PM2.5 effect estimates varied across regions, and further research is needed to explore the possible factors that modify or confound their association.

▼ The ultimate purpose was to assess if a whole glove dextrous robotic hand model provided results that differed from the reference modified closed-loop ASTM F739-99/12 glove permeation technique. The candidate compounds were low volatile solvents to minimize the influence of volatilization as a confounding factor. After preliminary closed-loop studies with 2-ethoxyethanol and 2-butoxyethanol showed the breakthrough times for purple nitrile disposable gloves were too short to be compared in the dextrous robotic hand model, limonene was selected to compare the permeation parameters of different disposable nitrile exam gloves (blue, purple, sterling, and lavender) In the modified closed-loop ASTM permeation model four 1-inch diameter standard permeation cells (3 cells with solvent as challenge and one air blank) were used with water as the collection solvent at 35 °C. Samples were analyzed by capillary gas chromatography-mass spectrometry and the internal standard method (4-bromophenol). For the static and moving whole glove model, a Yeager robotic hand and assembled. A circulating water system transferred water from between the outer test glove and the inner chemically protective glove of the doubly gloved robot hand in an incubator at 35.0±0.5 o C. The observed scheduled breakthrough time (SBRT) for blue, purple, sterling, and lavender glove specimens in the ASTM system was 70 ± 10 min, 30 ± 10 min, 15 ± 5 min, and 5 ± 5 min respectively. The two robot hand models showed similar SBRTs: 5 ± 5 min for lavender, 15 ± 5 min for sterling and purple, and 30 ± 10 min for blue gloves. The SBRTs for the blue and purple gloves for the robotic hand were significantly shorter than for the ASTM technique (P≤0.05). The average post-permeation thicknesses (before re-conditioning) for all glove materials for the moving and still robotic hand were more than 10% of the pre-permeation ones (P≤0.05) except for the blue gloves, although this was not so on reconditioning. The average steady state permeation rate (SSPR) for lavender glove for the static robotic hand was 0.423 ± 0.031 µg/cm2/min significantly higher (1.43 times) than for the ASTM method (0.295 ± 0.028 µg/cm2/min [P≤0.05]). Lavender gloves showed a significantly higher SSPR when the moving robotic hand was used (0.490 ± 0.031) compared to a non-moving one (P≤0.05). Although the respective SSPR for other gloves samples (blue, purple, and sterling) with the moving hand experiment appeared more than the static hand, the difference was not significant (P≤0.05). Here the exposed surface area was held constant as was temperature to assess if motion alone caused differences in permeation parameters. This suggests a thickness threshold for hand motion differences. The lavender, sterling, and purple gloves failed the Kimberly Clark Professional permeation breakthrough time criteria and Ansell's criteria for use, and therefore they should not be used as personal protective equipment for exposure to limonene, even for short exposure periods. Although blue…

▼ The valleys of northern Utah, where most of Utah’s population resides, experience episodic air pollution events well in excess of the National Ambient Air Quality Standards. Most of the events are due to an accumulation of particulate matter during persistent cold air pools in winter from both direct emissions and secondary chemical reactions in the atmosphere. High wintertime ozone concentrations are occasionally observed in the Uintah Basin, in addition to particulate matter. At other times of the year, blowing dust, wildland fires, fireworks, and summertime ozone formation contribute to local air pollution. The objective of this dissertation is to investigate one facet of the health effects of Utah’s air pollution on its residents: the acute impacts of air pollution on gastrointestinal (GI) disease. To study the health effects of these episodic pollution events, some measure of air pollution exposure must be matched to the health data. Time and place are used to link the health data for a person with the pollution data. This dissertation describes the method of kriging data from the sparse pollution monitoring network to estimate personal air pollution history based on the zip code of residence. This dissertation then describes the application of these exposure estimates to a health study on GI disease. The purpose of the GI study is to retrospectively look at two groups of patients during 2000-2014: those with autoimmune disease of the GI tract (inflammatory bowel disease, IBD) and those with allergic disease of the GI tract (eosinophilic esophagitis, EoE) to determine whether disease exacerbations occur more commonly during and following periods of poor air quality compared to periods of good air quality. The primary analysis method is case crossover design. In addition to using the kriged air pollution estimates, the analysis was repeated using simpler empirical estimation methods to assess whether the odds ratios are sensitive to the air pollution estimation method. The data suggests an association between particulate matter smaller than 2.5 microns and prednisone prescriptions, gastrointestinal infections in general, clostridium difficile infections specifically, and hospitalizations among people who have at least five entries of IBD diagnosis codes in their medical records. EoE exacerbations appear to be associated with high concentrations of particulate matter as well as ozone.
