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.Keywords
