叶菜类蔬菜中农药残留及膳食暴露风险评估

摘要： 目的 了解石家庄市叶菜类蔬菜农药残留现状，并评估农药残留的膳食暴露风险。方法 随机采集主要叶菜类样品682批，采用NY/T761-2008方法检测65种农药残留，分析叶菜类蔬菜农药残留现状，并结合我国居民蔬菜消费情况，用%ADI和%ARfD分别对农药残留进行慢性和急性膳食摄入暴露评估。结果 叶菜类蔬菜合格率98.97%，蔬菜检出率6.74%，农药检出率7.78%，超标率1.03%。超标农药为水胺硫磷和毒死蜱。%ADI和%ARfD膳食摄入风险均远小于1。结论 叶菜类蔬菜中各农药残留量风险均在安全范围内，农药残留的膳食暴露风险很小，水胺硫磷、毒死蜱是潜在的风险因子，应加强防患。

Residue and dietary exposure risk assessment of pesticide in leaf vegetables

Abstract: Objiective To study the current situation of pesticide residues in leaf vegetables in Shijiazhuang and to assess the risk of dietary exposure of pesticides. Method 682 leaf vegetable samples were collected randomly, 65 pesticide residues were detected according to the method of NY/T 761-2008, and the current situation of pesticide residues in leaf vegetables was analyzed. Based on the consumption of vegetables in China, the risk of chronic and acute dietary intake of pesticide residues was assessed by% ADI and% aRfD respectively. Result The qualification rate of leaf vegetables was 98.97%, the detection rate of vegetables was 6.74%, the detection rate of pesticides was 7.78%, and the over standard rate of pesticides was 1.03%. The over standard pesticides were thiamine and chlorpyrifos. The dietary risk of %ADI and %ARfD were less than 1. Conclusion The safety risks of pesticide residues in leaf vegetables are all within the acceptable ranges, and the dietary exposure risks of pesticide residues are very small. Thiamine and chlorpyrifos are potential risk factors, and should be paid more attention during the control of pesticide pollution.
