Impact/Purpose:
There is a need for development of sampling and analytical methods of priority chemical agents, such as toxic industrial chemicals, for environmental matrices. This analytical protocol is for the determination of the contaminants and were tested in a single-laboratory for measurement of the specific semivolatile organic compounds (SVOCs) in water, soil, air filters, and wipes. Analytes include Chlorfenvinphos, Chlorpyrifos, Dichlorvos, Dicrotophos, Disulfoton, Fenamiphos, Methyl parathion, Mevinphos, Parathion, Phencyclidine, Phorate, Phosphamidon, Tetramethylenedisulfotetramine (TETS), Crimidine, 1,4-Dithiane, 1,4-Thioxane, Chloropicrin, Strychnine, Tetraethyl pyrophosphate (TEPP), Dimethylphosphite, and Nicotine. This analytical protocol involves solvent extraction of the sample followed by gas chromatography/mass spectrometry analysis to determine SVOCs. This will allow evaluation of the extent of contamination and effectiveness of decontamination of these chemicals in the event of release into the environment. This would be used by those responding to such incidents, the laboratories responsible for analysis, and the results used by decision-makers.
