ARMI researchers in California published a paper today about their work on pesticide detection in Pacific chorus frogs (Pseudacris regilla) in the Sierra Nevada. The paper published today in the scientific journal Environmental Toxicology and Chemistry and under lead author Kelly Smalling, reports that several currentuse pesticides, especially fungicides, were found in the tissues of frogs collected from various remote and protected areas in California. Notably, on many occasions when pesticides were detected in the frog tissue, they were not detected in the accompanying water and sediment samples. www.usgs.gov/newsroom/article.asp
