PESTAB. The effects of the electrical discharge technique in selectively lowering detection limits on a wide range of pesticides is reported. Pesticides studies included diuron, atrazine, picloram, gamma-BHC (lindane), endosulfan, p,p'-DDT, PCP, monocrotophos, dimethoate, fenitrothion, diazinon, propoxur, methyl gusathion, and Perthane. The electrical discharge technique is extremely simple; 4 min in electrical discharge chamber, 8 min in 130C forced draft oven, and 12 min under 350 nm UV radiation. The method has application to a wide range of pesticides. Its uniformity compares with methods employing various spray reagents. Use of a single spray application prior to heating has improved detection limits in some cases.
