摘要
目的初步了解福建平潭地区市售水果中杀菌剂和杀虫剂类农药残留情况及风险。方法随机抽样平潭各农贸市场及超市的水果,采用QuEChERS方法对60份新鲜水果进行农药多残留萃取,利用在线凝胶渗透色谱-气相色谱-质谱联用技术(GPC-GC-MS/MS)测定15种农药的残留情况,并以目标危险系数(THQ)量化风险水平。结果所有水果样本中共检出6种农药,农药含量均未超过国家食品限量值,其最大目标危险系数均远小于1,表明平潭地区消费者通过水果摄入的农药处于安全水平。结论初步风险评价结果显示平潭市售水果中的杀菌剂和杀虫剂类农药不会对消费者造成明显的健康风险。
OBJECTIVE This research is advantage to preliminarily understand the residues and risks of fungicides and insecticides in fruits sold in Pingtan City.METHODS A total of 60 samples of different fresh fruits were analyzed.Fruitsextract by QuEChERS were randomly sampled from farmer′s market and supermarkets in Pingtan City.The residues of 15 pesticides in fruits was determined using the online GPC-GC-MS/MS.The risk level was quantified by Target Hazard Quotient(THQ).RESULTS The results showed that a total of 6 pesticides were detected in all samples,none of which exceeded the maximum residue limits for pesticides in food.And the maximum target hazard quotient were far less than 1,which means that the pesticides consumed by consumers through fruits in Pingtan were at a safe level.CONCLUSION It was proved by preliminary risk assessment that fungicides and insecticides in fruits did not lead to significant health risks to consumers in Pingtan City.
