Abstract Biological substances interfering with pesticide residue analysis are removed from hexane extracts of animal tissues by shaking them with concentrated H2SO4. Recoveries are reported for several chlorinated hydrocarbon pesticides and polychlorinated biphenyls (PCB) from fish extracts. This treatment destroys dieldrin and organophosphate pesticides, but affords a rapid, efficient, and economical cleanup of animal tissues for the analysis of DDT, PCB, and other acid-stable chlorinated hydrocarbon residues.

Abstract A method is presented for the rapid digestion and cleanup of animal tissues for pesticide residue analysis. Animal tissues are digested by a perchloric-acetic acid mixture to destroy the cellular structure and quantitatively liberate the pesticide-containing fat. The fat is extracted in n-hexane and destroyed on a sulfuric acid-Celite column. The common chlorinated pesticides (except aldrin, dieldrin, and endrin) can then be determined by a colorimetric or chromatographic procedure.

Abstract At least six cleanup procedures developed for the isolation of chlorinated hydrocarbon pesticides are described. Four procedures for organophosphate pesticide cleanup in plant extracts are also given. A combination of methods is suggested for a broad scope organophosphate pesticide cleanup technique.
