Estimated Toxicity to Aquatic Organisms in Midwestern Streams Driven by Relatively Few of the 227 Pesticides Analyzed
U.S. Geological Survey (USGS) scientists measured and estimated potential acute and chronic toxicity for 227 pesticides in agricultural and urban streams in Midwestern United States. Numerous pesticides were detected at low levels. Atrazine, acetochlor, metolachlor, imidacloprid, fipronil, selected organophosphate insecticides, and carbendazim were determined to be major contributors to toxicity...
