Abstract

PESTAB. A simple modification of the Hamence procedure can be used to identify alpha- and beta-endosulfan, dieldrin, endrin, and heptachlor epoxide. An extract containing insecticide is mixed with hydrochloric acid-acetic anhydride reagent, heated, cooled, and further mixed with distilled water and saturated sodium carbonate solution. Hexane is added to the solution, and the layers are allowed to separate. The organic layer is analyzed by electron capture gas chromatography using a 0.91 m X 0.73 cm Pyrex glass column packed with 10% OV-1 on GHP 80-100 mesh. All the compounds within a given fraction can be resolved, and there is no detectable blank from the reagent. The limit of detection in soil is in the range of 0.5-1.0 ppb.
