Effect of Pretreatment on Detection of 37 Pesticide Residues in .

This study aimed to develop a method, followed by gas chromatography-mass spectrometry, for detecting 37 pesticides in () and investigating the decrease in the matrix-induced enhancement effect. The influence of QuEChERS extraction and matrix solid-phase dispersion (MSPD) on the recovery and matrix effect (ME) was compared. extraction and matrix solid-phase dispersion (MSPD) on the recovery and matrix effect (ME) was compared to decrease the ME.
