A method for determination eleven trace organophosphorus pesticides in fruits and vegetables was studied by Gas Chromatography. These pesticides are methidophos, dichlorvos, acephate, omethate, phorate,dimethoate, carbofaran, parathion-methyl, fenitrothion, malathion and parathion. The recoveries of these organophosphorus pesticides are between the range of 77.4%～107.2%, and the RSD are between the range of 0.8%～6.4%. The method introduced here is simple, feasible and reliable. The obtained results are satisfactory.
