Abstract
An analytical procedure, based on sequential hexane and dichloromethane extraction followed by trimethylsilyl derivatization and capillary column GC-MS confirmation, has been developed for the verification of chemical warfare agents, their hydrolysis products and related compounds in soil. The chemical warfare agents, sarin, soman, and mustard, and the soman simulant, triethyl phosphate, were spiked onto five soils ranging from sand to sandy clay loam at 50 mu m/g and 5 mu m/g levels and recovered with efficiencies varying from nearly quantiative to about 5%. Recovery efficiencies were in the 50% to 90% range for most soil types contaminated with soman, mustard, and triethyl phosphate. Sarin recovery was generally lower with the lowest recoveries being observed for the sand and sandy clay loam soil types. TRUNCATED
