摘　　要：本文按照NY/T 761-2008标准方法,采用气相色谱仪检测了4992个蔬菜样品中14种有机磷农药的残留情况,并根据所得数据从不同季节、不同蔬菜种类等角度分析了蔬菜中农药残留的情况。结果表明农药残留超标情况集中出现在春秋季,而夏季超标率则较低,而且绿叶菜类蔬菜的超标状况最严重。此外,甲胺磷等禁用农药仍有一定的检出。本文还对蔬菜农药残留超标问题进行了初步分析,提出了一些参考措施。In this paper, 14 kinds of organophosphorus pesticide residues in 4992 vegetable samples were detected by gas chromatography through the NY/T 761-2008 standard method, and based on the data from the perspective of different seasons,different types of vegetable,the situation of pesticide residues in vegetables were analyzed.The results showed that excessive pesticide residues concentrate in spring and autumn, and lower in summer, and leafy green vegetables exceede the most serious situation.In addition,methamidophos and other banned pesticides still have certain detection.Finaly, the preliminary analysis over the issue of pesticide residues in vegetables was done and the proposal was put forward.
