Determination of pesticide residues in environment and food - a review
The literature analysis of 2017 - 2022 on the main features of the methods developed for the determination of pesticides in environment and food of plant and animal origin is presented. In sample preparation, the most popular are modern approaches combining simultaneous extraction, concentration and purification of samples, namely dispersion solid-phase extraction and dispersion liquid-liquid microextraction. The advantages of high-performance liquid chromatography in combination with mass spectrometry and universal methods of sample preparation for environmental and food safety monitoring are demonstrated. The possibility of simultaneous determination of pesticides of various classes and products of their transformation using HPLC in combination with high-resolution mass spectrometry and preliminary preparation of samples by the QuEChERS method is shown. Due to the possibility of more accurate masses determination, the method is successfully used in the analysis of parent compounds, their metabolites and is most promising for multicomponent analysis.
