ABSTRACT

An LC-MS/MS multi-residue method was validated for the determination of 59 pesticide residue levels in a chicken egg by using QuEChERS extraction method. The validation parameters used were taken from the SANTE/11813/2017 guideline. The calibration curves for each target pesticide had a good linearity in a range of 1.0 or 2.5 to 100.0 µg kg−1 (r2 ≥ 0.995). Ten per cent of the total pesticides had LOQ values less than 5.0 µg kg−1 or LOQ values from 5.0 to 10.0 µg kg−1. The LOQ values were below the MRLs set by the European Commision (EC). Average recoveries (70–120%) and relative standard deviations (RSDs≤20%) were achieved for 59 selected pesticides at different concentrations (5 or 10 and 200 µg kg−1). All expanded measurement uncertainties were lower than 50%. The occurrence of these pesticides was evaluated in 35 commercially available chicken eggs. No MRL exceedance was identified.

使用LC-MS / MS对土耳其鸡蛋中59种农药残留进行了调查。

摘要

通过QuEChERS提取方法验证了LC-MS / MS多残留方法用于测定鸡蛋中59种农药残留水平。使用的验证参数取自SANTE / 11813/2017指南。针对每个目标的农药校准曲线具有范围为1.0或2.5的良好的线性度到100.0微克千克-1(R 2  ≥0.995)。农药总量的10%的LOQ值小于5.0 µg kg -1或LOQ值从5.0至10.0 µg kg -1。LOQ值低于欧洲委员会(EC)设定的最大残留限量。选择59种不同浓度(5或10和200 µg kg -1的农药)的平均回收率(70–120%)和相对标准偏差(RSDs≤20%)。)。所有扩展的测量不确定度均低于50%。在35种市售鸡蛋中评估了这些农药的存在。没有发现最大残留限量。
