摘　　要：采用气质联用法同时测定了蔬菜、水果和大米中的22种有机氯和有机磷农药。样品经二氯甲烷萃取,浓缩后上机分析,采用选择离子监测模式扫描,外标法定量。该方法回收率范围为80.3%～117.0%,在检测浓度范围内保持良好的线性,相对标准偏差小于12%,检测限为0.001～0.1μg/mL。22 kinds of pesticides （including organochlorine pesticides and organophosphorus pesticides） were detected by GC--MS3100, which was produced by East and West Analitical In- struments. The pesticides were detected in SIM mode and by quantified by external standard. The method recoveries was between 80.3%- 117%, relative standard deviation was less than 12%, and had a good linearity.
