摘要
[目的]对都江堰市葡萄农药残留进行急性和慢性膳食摄入风险评估。[方法]2017-2018年对都江堰市生产的86批葡萄样品进行50种农药残留定量检测分析。[结果]2年抽检86个样品中有67个样品农药有检出,检出率为77.9%,有1个样品氯氟氰菊酯超标,超标率为1.2%。杀菌类农药嘧菌酯、多菌灵、腐霉利等检出率较高,膨大剂氯吡脲、多效唑均未检出,检出的农药有5种未在葡萄上登记。检出的14种农药慢性膳食摄入风险(%ADI)为0.01%~0.35%,急性膳食摄入风险(%ARfD)为0.31%~44.26%。根据残留风险得分,检出的农药有1种为高风险农药,其余13种农药为中低风险农药。按照风险指数(RI)排序,中风险样品占3.5%,低风险和极低风险样品占96.5%。[结论]出于保护消费者健康角度,建议吡虫啉、丙环唑、异菌脲、咪鲜胺4种农药最大残留限量分别设为6、7、6、1 mg/kg。
[Objective]To evaluate the risk of acute and chronic dietary intake of grape pesticide residues in Dujiangyan City.[Method]A total of 50 pesticide residues were quantitatively analyzed and analyzed in 86 batches of grapes produced in Dujiangyan City from 2017 to 2018.[Result]Among the 86 samples taken in two years,67 samples were detected,the detection rate was 77.9%,and one sample of cyhalothrin exceeded the standard.The over-standard rate was 1.2%.The detection rates of bactericidal pesticides such as azoxystrobin,carbendazim and procymidone were high.The swelling agents clopidogrel and paclobutrazol were not detected.Five kinds of pesticides were not registered on the grapes.The risk of chronic dietary intake(%ADI)of the 14 pesticides detected was 0.01%-0.35%,and the risk of acute dietary intake(%ARfD)was 0.31%-44.26%.According to the residual risk score,one of the pesticides detected was a high-risk pesticide,and the remaining 13 pesticides were low-and medium-risk pesticides.According to the risk index(RI),medium-risk samples accounted for 3.5%,and low-risk and very low-risk samples accounted for 96.5%.[Conclusion]From the perspective of protecting consumers’health,it is recommended that the maximum residue limits of imidacloprid,propiconazole,iprodione and prochloraz are set at 6,7,6 and 1 mg/kg,respectively.
