宁夏枸杞中高效氯氰菊酯残留的风险评估

目的]建立一套适合宁夏枸杞中农药残留的风险评估研究方法与模型.方法]通过对宁夏全区枸杞主栽区的枸杞进行抽样监测,对宁夏枸杞中高效氯氰菊酯农药残留进行了风险评估.结果]50％、90％、95％的人群人均每日通过食用枸杞摄入高效氯氰菊酯农药的量分别在6.63×10-6mg/kg（bw）或以下、2.17×10-5mg/kg（bw）或以下、2.83×10-5 mg/kg （bw）或以下,占ADI值的百分率分别不高于0.033 15％、0.108 50％、0.141 50％,安全系数在707 ～3 017,属于完全可以接受的水平,对消费者身体健康危害很小.结论]为宁夏乃至我国枸杞安全监管和农药残留限量提供了参考.

Risk Assessment on Beta-cypermethrin Residue in Lycium barbarum L.

Objective] The aim was to establish a set of study methods and models on risk assessment of pesticide residues for Lycium barbarum L..Method] Risk assessment on beta-cypermethrin residue in Lycium barbarum L.was carried out through sampling and monitoring in the main planting area of Ningxia autonomous region.Result] 50％,90％ and 95％ of the population intook beta-cypermethrin pesticide residues respectively in 6.63 x 10-6 mg/kg（bw） or below,2.17 x 10-5 mg/kg （bw） or below and 2.83 x 10-5 mg/kg （bw） or below per capita daily by eating wolfberry.And percentages of ADI values were less than 0.033 15％,0.108 50％ and 0.141 50％.The safety coefficient was 707-3 017,which belonged to an acceptable level completely,and the hazard was very little to consumers＇health.Conclusion] The results provide reference for safety supervision and pesticide residue limits in Ningxia,and even in China.
