Research progress in the sample pretreatment techniques and advanced quick detection methods of pesticide residues

The wide use of pesticides has cased serious environmental pollution and posed many potential health hazards. Therefore, it is of great importance to develop feasible, fast and accurate analysis methods for pesticide residues detection. Generally, pesticide residues exist in complex sample matrices and their concentrations are around µg/mL-ng/mL. Thus, sample pretreatment techniques are indispensible which could eliminate the interfering substances in the sample matrix, enrich analytes to reach to the detection level of analytical equipments, obtain the detection results with higher reliability and accuracy. Thus, this review mainly discussed the widely-used sample pretreatment techniques and advanced quick analysis methods for pesticides residues detection, then the prospects for pesticide residues analysis was proposed.
