Results of Analyses of the Fungicide Chlorothalonil, Its Degradation Products, and Other Selected Pesticides at 22 Surface-Water Sites in Five Southern States, 2003-04

Abstract

In accordance with% the mission of the U. S. Geological} Survey (USGS) Toxic Substances Hydrology Program, a pesticide study was conducted during 2003-2004 to determine the occurrence of the fungicide chlorothalonil and its degradation products at 22 surface-water sites in the Southern States. Water-quality samples were collected during the peanut-growing season (June-September) in 2OO3. During the peanut growing season in 2004, samples were collected after large storms. An analytical method was developed at the USGS Organic Geochemistry Research Laboratory in Lawrence, Kansas to measure chlorothalonil and its degradation products by liquid chromatography/mass spectrometry (LC/MS).
