中文摘要:
      目的 检测枸杞中的农药残留水平,并对拟除虫菊酯类农药的累积暴露风险进行评估,为是否需要制定枸杞中最大残留限量提供依据。方法 收集40份不同来源不同产地的枸杞样品,对332种农药残留进行测定,其中包括15种拟除虫菊酯类农药。采用危害指数(HI)法对通过枸杞摄入拟除虫菊酯类农药产生的急性和慢性累积风险进行评估。结果 通过方法学验证得出此方法适用于枸杞中拟除虫菊酯类农药的测定。结果显示4种拟除虫菊酯农药检出率均高于25%,分别为氯氰菊酯、氰戊菊酯、甲氰菊酯和氯氟氰菊酯。采用HI法进行累积暴露评估,得出拟除虫菊酯类农药的急性和慢性危害指数分别为0.497和0.016。结论 枸杞在拟除虫菊酯类农药的累积摄入风险虽然较小,但由于其检出率较高,应持续保持对样品的监控,并考虑制定相应的最大残留限量值。
Abstract:
      Objective In order to provide data for the formulation of maximum residue limitsassess (MRL) in wolfberry, the pesticide residues and the cumulative risk of pyrethroid were studied. Methods Three hundred and thirty-two kinds of pesticides including 15 pyrethroids in 40 samples which collected from different place were determined. Acute and chronic cumulative risk assessment were calculated by using hazard index approach. Results This method was appropriate to determine the pyrethroid residues in wolfberry by validation of the method. The result showed that the detecion rate of 4 pyrethroids was over 25%, including cypermethrin, fenvalerate, enpropathrin and cyhalothrin. The acute and chronic cumulative risk of pyrethroids in wolfberry was 0.497 and 0.016. Conclusion The cumulative exposure of 4 pyrethroids in wolfberry was small, but continuous monitoring should be maintained because of its high detection rate, and MRL also should be considered.
