Concentrations of parent pesticide and corresponding diethylphosphorus metabolites in blood serum and urine were investigated in persons who had ingested a concentrated solution of organophosphorus pesticide chlorpyrifos. The organophosphate poisoning was indicated by a significant depression of blood cholinesterase (EC

Recognition of exposure to diazinon, an organophosphate insecticide, was studied in goats. Urine and milk dialkyl phosphate concentrations (DETP; O,O-diethyl phosphorothionate) and blood cholinesterase activity (ChE) and diazinon concentrations were measured. Groups (n = 3 each) given (orally) diazinon at
