北京市昌平区本地蔬菜农药残留现状分析

Analysis of pesticide residues in local vegetables in Changping District,Beijing

【目的】为了解北京市昌平区蔬菜中农药残留污染情况,提升本地农产品供给的安全水平。【方法】于2022年对域内涉农镇街蔬菜生产基地和散户生产的635份蔬菜进行了75种农药残留检测。【结果】635份蔬菜样品农药残留检出率为22.0%(140/635),无农药残留超标情况;共检出15种农药残留,检出浓度最高的是氯氰菊酯0.44 mg/kg;检出率最高的是多菌灵7.2%;散户种植蔬菜中农残检出率高于规模基地;各类蔬菜中以茄果类蔬菜农药检出率最高(30.4%,9/69),其次为叶菜类蔬菜(27.4%,71/259)和根茎类蔬菜(18.1%,19/105);根据检出结果对75种农药进行风险等级划分,无高风险农药。【结论】昌平区本地蔬菜产品农药残留处于较低水平,但仍需加强监管,确保蔬菜供应安全。

[Objective]In order to understand the pesticide residue pollution situation in vegetables in Changping District,Beijing,and improve the security level of local agricultural product supply.[Methods]This study tested 75 pesticide residues in 635 vegetables produced by vegetable production bases and farmers in 2022.[Results]The detection rate of pesticide residues in 635 vegetable samples was 22.0%(140/635),and there were no cases of pesticide residues exceeding the standard;A total of 15 pesticide residues were detected,with the highest detected concentration being 0.44 mg/kg of Cypermethrin;The highest detection rate is 7.2%for Carbendazim;The detection rate of pesticide residues in vegetables grown by farmers is higher than that in large-scale bases;Among various vegetables,Solanaceous vegetables have the highest pesticide detection rate(30.4%,9/69),followed by leafy vegetables(27.4%,71/259)and rhizome vegetables(18.1%,19/105);Based on the detection results,75 pesticides were classified into risk levels,and there were no high-risk pesticides.[Conclusion]The current situation of pesticide residues in vegetable products in Changping District is at a relatively low level,but it’s still necessary to strengthen supervision to ensure the safety of vegetable supply and protect people's health.
