摘　　要：[目的]评估噻虫胺和虫螨腈在大葱中的残留消解及膳食摄入风险。[方法]通过规范田间残留试验,结合大葱中噻虫胺和虫螨腈的残留量,评估噻虫胺和虫螨腈的长期膳食摄入风险。[结果]噻虫胺和虫螨腈在大葱中的半衰期分别为4.6~7.4和5.8~6.9 d,均降解较快。长期膳食风险评估结果表明,普通人群中噻虫胺和虫螨腈的风险商(RQ)分别为5%和84%,对一般人群健康产生的风险是可接受的。[结论]按照推荐剂量使用,噻虫胺和虫螨腈在大葱中残留不会对我国人体健康产生影响。[Objective]To evaluate the residual digestion and dietary intake risks of clothianidin and chlorfenapyr in welsh onion.[Method]By conducting standardized field residue tests and considering the residual levels of clothianidin and chlorfenapyr in welsh onion,the long-term dietary intake risks of clothianidin and chlorfenapyr were evaluated.[Result]The half-lives of clothianidin and chlorfenapyr in welsh onion were 4.6-7.4 and 5.8-6.9 d,respectively,indicating faster degradation.The results of long-term dietary risk assessment indicated that the risk quotients(RQ)of clothianidin and chlorfenapyr in the general population were 5%and 84%,respectively,indicating that the risk of dietary intake was acceptable.[Conclusion]At the recommended dosage,the residues of clothianidin and chlorfenapyr in welsh onion have no effect on human health.
