    三唑类杀菌剂在蔬菜中的残留分布及对不同人群的累积性膳食摄入风险

    Residues distribution of triazole fungicides in vegetables and cumulative dietary intake risk to different populations

    • 摘要: 为探明蔬菜中残留的三唑类杀菌剂可能存在的累积性膳食摄入风险,本研究基于蔬菜样品检测获得的三唑类杀菌剂残留数据,分析了来自江苏省、浙江省、上海市、安徽省及福建省 5 个地区的 1612 批次蔬菜样本中 8 种三唑类杀菌剂的残留分布,并采用相对效能因子法以及概率评估方法的蒙特卡罗 (Monte Carlo) 模拟技术和 Bootstrap 抽样技术,对目标人群通过蔬菜摄入三唑类杀菌剂的累积急性及慢性暴露风险进行了评估。结果显示:检出较多的农药及产品组合为芹菜和西红柿中的苯醚甲环唑,检出率分别达到 23.1% 和 20.4%,其他检出率较高的农药还有三唑酮、戊唑醇、氟硅唑、烯唑醇、丙环唑、抑霉唑及腈菌唑。各类蔬菜中,黄瓜中三唑类杀菌剂残留对不同人群累积暴露量的贡献率最大,为 50%~70%。在第 97.5 百分位点处,蔬菜中残留的三唑类杀菌剂对各年龄段人群的累积慢性暴露量均低于慢性参考剂量 (ADI),其中 0~35 个月婴幼儿的累积慢性膳食摄入风险商 (%ADI) 值最高,平均为 34.6%,但仍低于100%;在第 99.9 百分位点处,蔬菜中残留的三唑类杀菌剂对各年龄段人群的累积急性暴露量均低于急性参考剂量 (ARfD),0~35 个月婴幼儿的累积急性膳食摄入风险商 (%ARfD) 值最高,平均为 51.7%,但也低于100%。研究表明,江苏、浙江、上海、安徽及福建 5 个地区蔬菜中三唑类杀菌剂残留的累积急性及慢性膳食摄入风险皆在可接受范围内。

       

      Abstract: In order to clarify the possible cumulative dietary intake risk of triazole pesticide residues in vegetables, the residues distribution of 8 triazole pesticides in 1612 batches of vegetable samples from 5 regions of Jiangsu Province, Zhejiang Province, Shanghai, Anhui Province and Fujian Province were analyzed based on the triazole pesticide residues data obtained from the detection of vegetable samples. The relative potency factor method, the Monte Carlo simulation technique and the Bootstrap sampling technique of probability assessment method were used to evaluate the acute and chronic risk of triazole pesticide intake from vegetables in the target population. The results showed that the most frequently detected pesticides and product combinations were difenoconazole in celery and tomato, and the detection rates reached 23.1% and 20.4%, respectively. Other pesticides with high detection rates were triadimefon, tebuconazole, flusilazole, diniconazole, propiconazole, imazalil and myclobutanil. Among all kinds of vegetables, cucumber contributed the most to the cumulative exposure of different populations, ranging from 50% to 70%. At the 97.5th percentile, the cumulative chronic exposure of triazole pesticides in vegetables to people of all ages was lower than the chronic reference dose (ADI), and the cumulative chronic dietary intake risk quotient of infants aged 0-35 months was the highest, with an average of 34.6%, but still less than 100%. At the 99.9th percentile, the cumulative acute exposure of triazole pesticides in vegetables to people of all ages was lower than the acute reference dose (ARfD), and the cumulative acute dietary intake risk quotient of infants aged from 0 to 35months was the highest, with an average of 51.7%, but also less than 100%. The study indicated that the cumulative acute and chronic dietary intake risks of triazole pesticide residues in vegetables in Jiangsu, Zhejiang, Shanghai, Anhui and Fujian were all within acceptable limits.
