摘　　要：目的:了解江西省南昌市本地市售蔬菜中农药残留污染现状。方法:在南昌市随机抽取了38个品种共181份新鲜蔬菜,参照全国食品污染物监测手册中推荐方法,采用气相色谱法对蔬菜中有机磷、有机氯、拟除虫菊酯、氨基甲酸酯四大类农药进行检测。结果:在所检测的样品中,农药残留检出率为49.72%。蔬菜样品中主要残留农药是甲萘威、三氯杀螨醇、联苯菊酯、氯氰菊酯、异丙威,其中最高残留量高达6.90 mg/kg。结论:南昌市售蔬菜农药污染仍然存在,要进一步加强蔬菜中农药污染监测力度,以便政府能及时了解食品的污染动态。Objective： To know the situation of pesticide residues in vegetables on the markets of Nanchang.Methods： According to the recommended items by the national food contamination monitoring manual,Gas Chromatography-Flame Photometry was applied to determine the contents of organophosphate pesticide,organochlorine pesticide,pyrethroid pesticide,carbamate pesticide in 38 kinds of vegetables samples.Results： The rate of detection for the pesticide residues was 49.72%,the main pesticide residues in vegetable samples were carbaryl,dicofol,bifenthrin,cypermethrin and isoprocorb,the peak level of residue reached 6.90 mg/kg.Conclusion： There were still pesticide pollution in vegetables in the markets of Nanchang city.Therefore,It′s necessary to strengthen the surveillance of pesticide residues and spread green non-pollution vegetables.It is necessary to further strengthen the food safety control through monitoring food pollution trend.
