Abstract
This article summarizes the results of validation studies of a multi-residue method for the determination of pesticide residues in fruits and vegetables. The results of some of the monitoring control programs carried out in Romania are also presented. Liquid chromatography coupled with mass spectrometry (LC-MS / MS) was used to assess pesticide residue levels. The QUECHERS extraction method was used to extract the compounds. To validate the method, the control samples were fortified with a solution of 74 pesticides for LC-MS / MS analyzes, at 3 levels.The validation study is based on the regulations in Document DG Nº SANTE / 12682/2019. The scope of validation included the following performance requirements: Limit of detection; Quantification limit; Recovery; Fidelity; Repeatability; Reproducibility; Recovery; Selectivity / Specificity; Stability / Robustness; Linearity; Matrix effect; Measuring the margin of error.
