Dissipation Behavior and Risk Assessment of Three Pesticide Residues Under Combined Application in Greenhouse-Grown Cabbage.

ABSTRACT: Field residue trials were conducted in greenhouse-grown cabbage at both recommended and double dosages to evaluate the degradation dynamics and dietary risks of three pesticides (azoxystrobin, thiamethoxam, and carbendazim). In this study, a quick, easy, cheap, effective, rugged, and safe (QuEChERS) method combined with liquid chromatography tandem mass spectrometry was developed to measure the residues of three pesticides in cabbage. The mean recoveries of three pesticides in cabbage were 82.5-104.2%, with relative standard deviations of 2.1-5.2%, meeting the requirements of residual analysis. Based on first-order kinetics, the half-lives of the three pesticides in cabbage were 11.55-33.00 d under field conditions. The health risks associated with three pesticides in cabbage were evaluate
