In order to clarify the influence of pesticide residues in vegetables on the matrix effect,three kinds of vegetables,leek,celery and eggplant,were selected in this paper.The six pesticide residues in vegetables were determined by liquid chromatography-tandem mass spectrometry.The matrix effect was determined by the slope of the matrix and solvent standard curve.The results showed that the matrix effect of pesticide residues in different vegetables was mainly signal inhibition.Therefore,in the later pesticide detection,the matrix standard curve can be used for quantitative determination,so as to improve the accuracy of the test results,which is of great significance for ensuring food safety.
