We have developed a simple and rapid method for measuring 11 organophosphorous pesticides (dichlorvos, methidathion, salithion, malathion, fenitrothion, fenthion, parathion, diazinon, ethylthiometon, O-ethyl O-(4-nitrophenyl) phenylphosphonothioate (EPN) and chlorpyrifos) and one metabolite (3-methyl-4-nitrophenol) of fenitrothion in serum and urine of acute poisoning patients by HPLC with a diode-array detector.
An aliquot of the biological sample after deproteinization by acetonitrile was injected into C18 column using acetonitrile-water as a mobile phase.
