Analysis of Selected Organic Priority Pollutants in Environmental Samples

摘要

The analysis of drinking water for pesticides, herbicides, and volatile organic compounds will probably be the environmental analytical chemist's introduction to the Environmental Protection Agency (EPA) list of organic priority pollutants. The State of Tennessee requires that drinking water be monitored for lindane, endrin, methoxychlor, toxaphene, 2,4-D, silvex, and the trihalomethanes (THM). In the past two years our attention has been particularly focused on the analysis of polyclorinated biphenyl (PCB) in an increasingly wide variety of sample types. This paper will describe the Oak Ridge Y-12 Plant Laboratory's experience in the analysis of environmental samples for these particular organic priority pollutants by gas chromatography with electron capture detection. Preparation and cleanup procedures for many sample types, chromatographic interpretation, column selection, and confirmatory tests will be discussed and evaluated. (ERA citation 05:037180)
