1. Blake, Deanne Renee. Effects of Layer Double Hydroxide Nanoclays on the Toxicity of Copper to Daphnia Magna.

Degree: 2012, University of North Texas

Nanoparticles may affect secondary pollutants such as copper. Layer Double Hydroxides (LDH) are synthetically produced nanoparticles that adsorb copper via cation exchange. Pretreatment of copper test solutions with LDH nanoparticles followed by filtration removal of LDH nanoparticles demonstrated the smallest LDH aggregates removed the most copper toxicity. This was due to increased surface area for cation exchange relative to larger particle aggregates. Co-exposure tests of copper chloride and clay were run to determine if smaller clay particles increased copper uptake by D. magna. Coexposure treatments had lower LC50 values compared to the filtration tests, likely as a result of additive toxicity. LDH nanoclays do reduce copper toxicity in Daphnia magna and may serve as a remediation tool. Advisors/Committee Members: Roberts, Aaron P., Klaine, Stephen J, D’Souza, Nandika.

2. Alloy, Matthew Michael. Effects of Suspended Multi-Walled Carbon Nanotubes on Daphnid Growth and Reproduction.

Degree: 2010, University of North Texas

Multi-walled carbon nanotube aggregates can be suspended in the aqueous phase by natural organic matter. These aggregates are ingested by filter feeding zooplankton. Ingested aggregates result in decreased growth and decreased reproduction. These effects may be caused by reduction in energy input from normal feeding behavior. pH alters natural organic matter structure through changes in electrostatic repulsion. Altered natural organic matter structure changes multi-walled carbon nanotube aggregate size. This size variation with variation in pH is significant, but not large enough a change in size to alter toxicity, as the aggregate size range remains well within the particle size selection of the organisms. Advisors/Committee Members: Roberts, Aaron P., Venables, Barney J., Huggett, Duane B., Klaine, Stephen J..
