A rapid, easy and versatile, simultaneous analytical method by LC-MS/MS based on extraction of QuEChERS method (EN 15662:2008) was developed for the determination of residual pesticides in agricultural products. In this method, it allowed to prepare a test solution only dilution without purification using solid phase extraction column. The method was assessed for 210 pesticide residues in 21 kinds of vegetables and fruits at the fortification levels of 0.01 and 0.1 μg/g according to the method validation guideline (Ministry of Health, Labour and Welfare of Japan). As a result, 194 to 210 analytes met the management criteria of the guideline. Thus, the present method could be useful for a rapid simultaneous determination of residual pesticides in agricultural products.
建立了一种基于QuEChERS方法（EN 15662:2008）萃取的快速、简便且通用的液相色谱-串联质谱同时分析方法，用于测定农产品中的残留农药。在该方法中，无需使用固相萃取柱进行净化，仅通过稀释即可制备测试溶液。根据日本厚生劳动省的方法验证指南，在0.01和0.1 μg/g的加标水平下，对21种蔬菜和水果中的210种农药残留进行了该方法的评估。结果表明，194至210种分析物符合该指南的管理标准。因此，本方法可用于快速同时测定农产品中的残留农药。
