新疆甜瓜农药残留膳食风险评估

以两年度新疆主产区127个甜瓜样品为研究对象,在完成甜瓜中60项农药残留分析的基础上,通过慢性、急性膳食暴露评估,对其膳食风险水平进行评估,同时采用英国兽药残留委员会兽药残留风险排序矩阵,探讨高风险残留农药种类。结果显示:甜瓜样品中检出苯醚甲环唑、毒死蜱、啶虫脒、多菌灵等10种农药残留,检出率在0.79%～22.05%;残留农药的慢性膳食摄入风险值和不同人群的急性膳食摄入风险值均远低于100%,毒死蜱、苯醚甲环唑和虫螨腈风险得分分别为24.03,18.12,18.05,高于其他种残留农药,样品存在农药残留的现象;但其膳食风险不高,毒死蜱、苯醚甲环唑和虫螨腈为高风险残留农药,需加强关注。

Risk assessment of pesticide residues in muskmelon in xinjiang

To evaluate the dietary risk level of pesticide residues in muskmelon in Xinjiang and identify the types of pesticide residues with relatively high risks. Based on the research of 127 muskmelon samples of the 2-year-producing in Xinjiang, 60 kinds of pesticide residues were analyzed by chronic, and the acute dietary exposure assessment, and the dietary risk levels were evaluated. Moreover, the usage of veterinary drug residue council sort veterinary drug residue risk matrix, and the pesticide residue in high-risk types were discussed. The results showed that 10 kinds of pesticide residues, icluding phenyl ether metronidazole, chlorpyrifos, chlordimeform, and chlorphenidine, were detected in the melon samples, and the detection rate ranged from 0.79% to 22.05%. The risk of chronic dietary intake (%ADI) and acute dietary intake (%ARfD) of pesticide residues in different populations were significantly lower than 100%. The risk scores of chlorpyrifos, phenyl ether metronidazole, and dinitrile were 24.03, 18.12 and 18.05, respectively, showing higher than those of other pesticide residues. Most importantly, chlorpyrifos and phenyl ether metronidazole were high-risk residual pesticides, and we need to be very careful of the usage of them.
