Graduate Theses/Dissertations
The contamination of perfluorooctanesulfonic acid (PFOS, C8F17SO3H) in water is considered a threat to humans and the environment. The strength of carbon and fluorine bond is responsible for its high stability in the environment. Therefore, it can be transferred from the environment to food sources and eventually humans. This study assessed the ability of nanoparticles to adsorb PFOS from water. The experiment was performed by preparing suspensions of PFOS (10 ppm) and different concentrations (1000 ppm, 500 ppm, 250 ppm) of cerium oxide nanoparticles (CeO2-NPs) or magnesium oxide nanoparticles (MgO-NPs). The suspensions …

Macrophytes And Atrazine In Ponds Of Southwest Missouri, Christine Michelle Cornish
Graduate Theses/Dissertations
Wetlands are often the ultimate destination of agrochemicals. The increased use of these pollutants has resulted in their increased transport, via runoff and spray drift, into wetlands. Atrazine, a commonly used herbicide, has been detected in surface water, groundwater, soil, and sediment, and has shown to have adverse impacts on aquatic biota, such as fish and amphibians. Few studies have reported on the relationships between atrazine and macrophytes. I measured atrazine concentrations in surface sediments in agricultural, conservation, and golf course ponds of southwest Missouri, and investigated how those concentrations might be related to macrophyte communities, and pond environmental characteristics. …
