中文摘要:

      目的 评估河北省设施黄瓜农药残留状况和居民的膳食摄入风险情况。方法 对采自河北省藁城县、高邑县、徐水县、永清县、肃宁县和承德县的90份设施黄瓜样品进行农药残留检测, 分别通过每日允许摄入量(acceptable daily intake, ADI)和急性参考剂量(acute reference dose, ARfD)进行农药残留慢性膳食摄入风险评估和急性膳食摄入风险评估, 借鉴英国兽药残留委员会兽药残留风险排序矩阵进行风险排序。结果 检测的87种农药中有26种农药检出残留, 检测的90份样品的阳性样品比率为100.0%。不同人群的慢性膳食摄入风险(在0%~17.58%之间)和急性膳食摄入风险(在0.06%~55.81%之间)都远小于100%。根据残留风险得分, 高风险农药有3种, 即阿维菌素、联苯菊酯和毒死蜱。结论 河北省设施黄瓜农药残留检出率较高, 但仅有1个样品的农药残留超标, 残留农药对居民的膳食摄入风险均很低。建议优先登记盐酸吗啉胍等抗病毒药物在黄瓜上的使用, 并制定盐酸吗啉胍在黄瓜上的最大允许残留限量标准。

英文摘要:

      Objective To evaluate the pesticide residue status of facility cucumbers and the dietary intake risk of residents in Hebei Province. Methods Pesticide residues were detected in 90 cucumber samples collected from Gaocheng County, Gaoyi County, Xushui County, Yongqing County, Suning County and Chengde County of Hebei Province. Chronic dietary intake risk and acute dietary intake risk of pesticide residues in these samples were performed by acceptable daily intake (ADI) and acute reference dose (ARfD), respectively. The risk ranking was carried out referring to the Matrix Ranking developed by the Veterinary Residues Committee of the United Kingdom. Results The 26 of 87 pesticides were detected as residues, and 100.0% of cucumber samples (90/90) had detectable residues. For different populations, the chronic dietary intake risks ranged from 0% to 17.58%, and the acute dietary intake risks ranged from 0.06% to 55.81%, and both dietary intake risks were far less than 100%. According to the risk score, there were 3 kinds of high risk pesticides, including avermectin, bifenthrough and chlorpyrifos. Conclusion Pesticide residues in facility cucumbers from Hebei Province have a high detection rate. While only one sample exceeds the standard, and the pesticide residues have a relatively low dietary intake risk for different age groups. It is recommended to register the use of antiviral pesticide such as moroxydine hydrochloride on cucumber, which the maximum pesticide level value is proposed to be established.
