目的了解杭州地区食品中氨基甲酸酯类农药的污染状况,为食品质量安全的监管和控制工作提供科学依据。方法 2013年采集杭州地区食品样品166份,其中食用菌30份,茶叶30份,蔬菜80份,水果26份,采用超高效液相色谱-串联质谱法(UPLC-MS/MS)测定灭多威、抗蚜威、残杀威、克百威、甲萘威、异丙威、仲丁威和速灭威8种氨基甲酸酯类农药。结果 166份样品中,共检出3种氨基甲酸酯类农药(克百威、灭多威和异丙威),检出率为2.41%,检出范围为0.013 mg/kg~0.180 mg/kg,其中克百威的检出率最高(1.20%),其次为灭多威和异丙威(均为0.60%)。此外,仅有克百威这一种氨基甲酸酯农药出现超标现象,超标率为0.60%。食用菌、茶叶、蔬菜和水果4种食品中氨基甲酸酯类农药的检出率分别为3.33%、3.33%、1.25%和3.85%。结论杭州地区食品中氨基甲酸酯类农药残留水平较低,质量安全状况良好,但是残留超标事件还是偶有发生。
Objective To understand the pollution status of carbamate pesticides in food in Hangzhou and provide a scientific basis for the supervision and control of food quality and safety. Methods A total of 166 food samples were collected from Hangzhou in 2013, including 30 edible mushrooms, 30 tea leaves, 80 vegetable and 26 fruits. The content of methimazole was determined by UPLC-MS / MS , Pirimicarb, propoxur, carbofuran, carbaryl, isoproxil, sec-butyl and monosulfam 8 carbamate pesticides. Results Among the 166 samples, three carbamates (carbofuran, methomyl and isoprocarb) were detected with a detection rate of 2.41% and the detection range was 0.013 mg / kg ~ 0.180 mg / kg Among them, the highest detection rate of carbofuran (1.20%), followed by methomyl and isoprazole (both 0.60%). In addition, only carbamate carbamate pesticide exceeded the standard phenomenon, exceeding the standard rate of 0.60%. The detection rates of carbamate pesticides in edible fungi, tea, vegetables and fruits were 3.33%, 3.33%, 1.25% and 3.85% respectively. Conclusion The residues of carbamate pesticides in foodstuffs in Hangzhou are low and the quality and safety are in good condition. However, occasional residues of carbamate pesticide residues occur occasionally.
