Abstract Blood cholinesterase activity, urinary levels of phenolic and organophosphorus metabolites, and residues of intact compounds in blood and fat were determined following exposure of rats to organophosphorus pesticides. The eight pesticides studied included representative halogenated compounds (carbophenothion, dichlofenthion, ronnel, and leptophos) and nonhalogenated compounds (parathion, EPN, dimethoate, and dichlorvos). Cholinesterase activity was determined by gas chromatography. Metabolites were extracted, derivatized, subjected to silica gel chromatography, and quantitated with FP-GC and EC-GC. Residues were extracted, cleaned up with silica gel chromatography, and quantitated with EC-GC. Data comparing these various exposure indicators are presented.
