Objective To establish a method for the simultaneous determination of 55 pesticide residues in vegetable oil and animal tissues. Methods The samples were extracted and purified by a modified QuEChERS method, and then the supernatant was analyzed by on-line gel permeation chromatography coupled with gas chromatography-mass spectrometry (GPC-GC-MS) system.Results The calibration curves of 55 pesticide residues were linear in the range of 0.01~0.20 mg/L with good correlation coefficients more than 0.992, The recoveries of the method ranged from 60% to 130%, The limits of quantification were 0.005~0.03 mg/kg.ConclusionThe method is simple, rapid and reliable and can meet the requirement the simultaneous determination and analysis of 55 pesticide residues in vegetable oil and animal tissues.
