A multi-component quantitative GC-MS/MS method for monitoring and inspecting agricultural products was developed for the simultaneous determination of 365 pesticide residues in grain, beans, fruit and vegetables. Twenty-six pesticides that have been authorised in foreign countries but not in Korea were included in the newly adapted Korean positive list system. The method was validated by analysing spiked samples at three concentrations (0.01, 0.05, and 0.1 mg/kg) for brown rice, soy beans, mandarin orange, potato and green pepper matrice, which represented grain, beans, fruit, and vegetables. More than 95% of 365 compounds satisfied the validation criteria of 70-120% recovery and ≤20% relative standard deviation obtained through the proposed simultaneous multi-component analysis. Twenty-two types of pesticides were detected in 76 food samples, whose concentrations were below the maximum residue limits. Among the newly added pesticides, lambda-cyhalothrin, an analogue of cyhalothrin, was detected in peaches. The method can be applied to the analysis and inspection of pesticide residues in domestic and imported agricultural products for safety control.
建立了一种用于监测和检查农产品的多组分定量 GC-MS/MS 方法，用于同时测定谷物、豆类、水果和蔬菜中的 365 种农药残留。新适应的韩国阳性清单系统中包含了 26 种在国外获得授权但在韩国未获得授权的农药。该方法通过在糙米、大豆、蜜柑、土豆和青椒基质中分析三个浓度（0.01、0.05 和 0.1 mg/kg）的加标样品进行验证，这些基质代表谷物、豆类、水果和蔬菜。365 种化合物中的 95%以上满足 70-120%回收率和≤20%相对标准偏差的验证标准，这些标准是通过建议的同时多组分分析获得的。在 76 份食品样品中检测到 22 种农药，其浓度低于最大残留限量。在新添加的农药中，氯氟氰菊酯的类似物氯氟氰菊酯在桃中被检出。该方法可用于分析和检测国内和进口农产品中的农药残留，以进行安全控制。
