摘      要：A complete set of procedure for determination of multiresidue of pesticides in vegetables was presented in this *** complete set of procedure included three steps:bioassay,cholinesterase inhibition and GLC *** samples could be identified to be contaminated with pesticides if 5% of house flies was knocked down in 50 tested house flies. Those samples contaminated with pesticides needed to be detected by AChE inhibition *** qualitative and quantitative analyses were carried out by *** ranged from 83.7% in Chinese cabbages to 105.6% in tomatoes for pyrethroids,and 84.0% in tomatoes to 102.7% in sweetbell redpeppes for organophosphorus *** of variations ranged from 0.59% to organophosphorus *** of variations ranged from 0.59% to 7.87% for pyrethroids. and 0.33% to 9.88% for organophosphorus compounds with vegetables. The complete set of procedure has been used successfully to analyze 7000 samples collected in Beijing. About 1% of the samples had a pesticide content exceeding the MRL.
