Pesticides and Pesticide Degradates

Amphibians from remote locations in California have accumulated several current-use pesticides, including fungicides, in their bodies. A team of U.S. Geological Survey (USGS) scientists recently reported on field results in the journal Environmental Toxicology and Chemistry. Two fungicides, pyraclostrobin and tebuconazole, and the herbicide simazine were detected frequently in amphibians from all...

Crab embryos from two Northern California salt marshes accumulate mixtures of currently used as well as discontinued pesticides, according to a study published by U.S. Geological Survey (USGS) and University of California scientists in the journal Environmental Toxicology and Chemistry.

Researchers with the U.S. Geological Survey (USGS) recently investigated 51 streams in nine Midwestern States to determine the presence of a wide range of herbicides, their degradation byproducts and antibiotics. Herbicides were detected in most water samples, which were collected to coincide with runoff events following herbicide application, but antibiotics were detected in only 1 percent of the...
