摘　　要：为评估福建省主产区普通白菜中农药残留水平及对人体的膳食暴露风险,采用现有的标准检测方法,对在福建省主产区采集的88个普通白菜样品中的68种农药残留进行了检测分析,并对检出农药进行了短期和长期膳食暴露风险评估。结果显示:88个普通白菜样品中,共有68个样品检出了农药残留,总检出率为77.27%;共检出27种农药,其中杀虫剂18种,杀菌剂9种;检出2种及2种以上农药残留的样品占检出农药残留样品总量的83.82%,存在农药多残留现象。利用相关农药的毒理学数据——急性参考剂量(ARfD)和每日允许摄入量(ADI)、农药残留数据和普通白菜的膳食消费量数据,评估了所检出农药的短期和长期膳食暴露风险。其中,短期膳食暴露风险值(%ARfD)范围为0~90%,长期膳食暴露风险商贡献率(RQc%)范围为0~46%。研究表明,福建省主产区普通白菜中的农药残留水平较低,通过食用该地区生产的普通白菜对消费者的农药残留膳食暴露风险整体在可接受范围内。In order to investigate the pesticide residue levels in pak-choi(Brassica rapa ssp.chinensis)in the main producing areas of Fujian Province,and to assess the dietary exposure risks to human body,88 samples were collected and detected using the standard residue analytical method of 68 pesticides in vegetables,and the short-term and long-term dietary exposure risks were assessed.The results showed that 68 samples were detected with pesticide residue in 88 pak-choi samples,and the total detection rate was 77.27%;27 pesticides were detected,including 18 insecticides and 9 fungicides.The samples with 2 or more detected pesticides accounted for 83.82%of the total samples with detected pesticide residues,which means that the multiple pesticide residues occurred.Using the pesticide toxicology data,acute reference dose(ARfD),acceptable daily intake(ADI),residue data,and pak-choi consumption data,the risk assessment of detected pesticides showed that the short-term dietary exposure risk(%ARfD)ranged from 0 to 90%,and the contribution rate of the long-term dietary exposure risk(RQc%)ranged from 0 to 46%.The results showed that residue levels of detected pesticides in pak-choi were low,and the dietary exposure risk was acceptable for customers to consume pak-choi produced in Fujian Province.
