Neonicotinoid Pesticide And Nitrate Removal In Floating Treatment Wetlands, Julia Lindgren
Neonicotinoid Pesticide And Nitrate Removal In Floating Treatment Wetlands, Julia Lindgren
Department of Environmental Engineering: Theses and Student Research
Nutrient and pesticide concentrations in surface water are a growing concern in the Midwest. Floating treatment wetlands (FTWs) are often used to remove excess nutrients from surface water and should be considered for removal of emerging contaminants, such as neonicotinoids. Therefore, the objectives for this research project were: 1) Determine FTW neonicotinoid removal capacity, 2) Quantify neonicotinoid incorporation into floating macrophytes, and 3) Explore potential implications of neonicotinoids on microbial denitrification. A microcosm and mesocosm experiment was completed. The mesocosm experiment evaluated 3 treatments: 1) FTW mesocosm with neonicotinoids, 2) FTW without neonicotinoids, and 3) mesocosm with neonicotinoids and without …
Pesticide Occurrence And Persistence Entering Recreational Lakes Residing In Watersheds Of Various Land Uses, Jessica Satiroff
Pesticide Occurrence And Persistence Entering Recreational Lakes Residing In Watersheds Of Various Land Uses, Jessica Satiroff
Department of Environmental Engineering: Theses and Student Research
Common Use Pesticides (CUPs) are important for agricultural producers to sustain food production. As a result, regions with high rates of agricultural production, such as the Midwest, often have ubiquitous occurrences of pesticides in surface and groundwater 1. Once pesticides are introduced into an ecosystem, pesticides have the potential for creating unwanted effects on non-target species and downstream environments 2,3. However, pesticides do not come strictly from agricultural practices. Therefore, the research presented in this thesis focuses on the neonicotinoid and fungicide concentrations detected in recreational lakes as well as their persistence in these aquatic environments during the …
