Degradation products of diazinon and dichlorvos, organophosphorus pesticides, were investigated, and their degradation time-courses were also examined. The degradation of both compounds was carried out under the condition of static state in aqueous solution and hydrochloric acid solution (pH 2.0) at 37℃. By gas chromatography (GC), peaks of diazinon and dichlorvos were not observed in sample solutions after about 20 d. Degradation products of diazinon, and dichlorvos were identified to be 2-isopropyl-4-methyl-6-hydroxypyrimidine and dichloroacetaldehyde by gas chromatography-mass spectrometry (GC-MS), respectively. These degradation products were determined by thin layer chromatography, GC and (GC-MS).
