A multi-residual method using gas chromatography coupled with mass spectrometry (GC/MS/MS) was developed for the analysis of 105 pesticides. This method was tested on lemons, beans and other vegetables. The pretreatment of these pesticides was performed by liquid-liquid partition followed by cleanup with solid phase extraction cartridge (SPE Florisil), after acetonitrile extraction from matrices and sodium chloride (15 g) addition. The recovery ranged from 71.1% to 126.0% except for azinphosmethyl,famoxadone, fenamidone, flufenoxuron and triadimefon in lemons and from 72.5% to 124.5%in bean. In lemon, the limit of detection (LOD) and limit of quantification (LOQ) were 0.001~150 ng/mL and 0.004~500 ng/mL, respectively.
