Determination of 19 Carbamate Pesticide and Metabolites Residues in Eggs by QuEChERS-UPLC-MS/MS

Abstract

The residues of 19 carbamate pesticides and their metabolites in eggs were determined by QuEChERS-UPLC-MS/MS. Egg samples were extracted by acetonitrile, purified by dispersion solid phase extraction, and determined by UPLC-MS/MS. The linearity of 19 carbamate pesticides and their metabolites in the range of 0.2~50 ng/mL was good (R2>0.999), and the detection limit of the method was 1.0~10 μg/kg. The recoveries were 69.3%~107.6 % and RSD was lower than 9.21% at 10, 20 and 50 μg/kg. The method is simple, rapid, efficient and accurate with high recovery, and can meet the needs of detection and confirmation of 19 carbamate pesticides and their metabolites residues in eggs.
