Pesticide Contamination in Varied Pesticide-Use Settings
New pesticides are developed continually, and increasingly, degradation byproducts of legacy and current-use pesticides are discovered. Information on the environmental occurrence of these chemicals is needed to evaluate their potential environmental and human health significance. This project activity has two-fold objectives: (1) develop methods to measure new pesticides and their byproducts in samples of various environmental media at concentrations relevant to assessing their persistence, transport, and fate; and (2) gather information on the environmental occurrence of these chemicals in sensitive and/or susceptible ecosystems near areas of common use of the pesticide, such as areas of similar land use, crop types, and/or farming practices. Pesticide-use studies in selected settings include:
Herbicides and other Agricultural Chemicals -- Midwest Cornbelt
Cotton Agriculture -- Southern United States
Agricultural Chemicals in Ground Water -- Plains, Georgia [Completed]
Transport of Herbicides in Streams and Shallow Ground Water , Cedar River, Iowa [Completed]
