Abstract: This study used gas chromatography to analyze the matrix effcts of 1O fruit species from five categories,including pome and stone fruits,on eight organophosphorus pesticides.Results showed that the matrixenhanced effect was observed across the different fruit matrices.While the enhancement generally decreased with increasing pesticide concentration,most maintained a significant effect, with the matrix-enhancing effect being more pronounced at lowconcentrations.Matrix effcts varied acrossfruitcategories and were associated with fruit components such as pectin,sugars,organic acids,terpenes,and esters and pesticide properties.This study provides theoretical support for optimizing pesticide residue detection methods and improving detection accuracy.
