摘　　要：【目的】对猕猴桃中农药残留进行膳食暴露风险评估,量化常用农药膳食摄入风险水平,为安全生产、指导消费、安全监管、MRLs制(修)订提供科学依据。【方法】测定某一主产区猕猴桃果实样品中66种农药残留,分别用%ADI和%ARfD对检出农药进行慢性和急性膳食摄入风险评估,借鉴英国兽药残留风险排序矩阵进行农药和样品风险排序,计算最大残留限量估计值(eMRL),为制定相应农药最大残留限量值(MRL)提供参考。【结果】(1)共检出农药21种,均为中等毒或低毒农药;(2)检出农药除啶虫脒、灭幼脲无ARfD信息外,其余19种农药%ADI和%ARfD均明显小于100%;(3)检出农药中溴氰菊酯和毒死蜱为中风险农药(15≤S<20),其余均为低风险农药(S<15)。98.4%的样品为中、低、极低风险样品;(4)给出了无限量值的噻虫嗪、吡虫啉、甲基硫菌灵等12种农药的最大残留限量估计值eMRL。【结论】检出农药的急、慢性膳食风险均在可接受范围内,98.4%的样品处于中、低或极低风险区域,总体来说该主产区猕猴桃质量安全状况良好。建议制定猕猴桃中噻虫嗪等12种农药的MRLs。【Obiective】Risk assessment of dietary exposure to pesticide residues in kiwifruit and quantifiction of the dietary risk levels of commonly used pesticides provide references for safe production and guidance for consumption of the fruit,food safety supervision,and revision of the Maximum Residue Limits(MRLs)of kiwifruit.【Methods】Based on detection of the residues of 66 pesticides in 61 kiwifruit samples from a major producing area,chronic dietary intake risk(%ADI)and acute dietary intake risk(%ARfD)of pesticide residues in these samples were assessed.Based on the veterinary drug residue risk ranking matrix constructed by the British Veterinary Drug Residues Committee,the risk of th epesticides and samples was ranked by integrating kiwifruit consumption and pesticide toxicity,frequency of use and residue level,and maximum residue limit estimates(eMRL)were calculated using allowable daily intake(ADI)values,large portion consumed(LP),and body weight(bw).The study will provide a reference for the regulation of the maximum residue limit(MRL)for the corresponding pesticides.【Results】(1)Among the 62 pesticides,a total of 21 pesticides were detected,and they were lowtoxic pesticides except for chlorpyrifos,deltamethrin,cypermethrin and cyhalothrin,which were moderately toxic;(2)Using the pesticide toxicology data,acceptable daily intake(ADI)and acute reference does(ARfD),residual data and kiwifruit consumption data,the risk assessment of the 21 pestcides detected showed that the chronic dietary intake(%ADI)of each pesticide in kiwifruitranged from 0.000 01%to 0.016 04%.All the 21 pesticides detected but acetamiprid and chlorpyrifos without ARfD information had an acute dietary intake(%ARfD)ranging from 0.01%to 26.20%.The acute dietary intake risk difference between different pesticides was significantly.(3)According to the residual risk score,the 21 pesticides detected were medium-to low-risk pesticides.The risk scores for deltamethrin and chlorpyrifos were 16.5 and 16.1 ie(15≤S<20),respectively,which were i
