title: [Multiresidue method for determination of pesticides in fruits and vegetables by GC/MS (SCAN) and LC/MS (SIM)].
abstract: A rapid multiresidue method has been developed for determination of many pesticides in fruits and vegetables using GC/MS and LC/MS. The method of analysis was the same as that reported by Kakimoto et al. in 2003 except for the use of LC/MS. Good recoveries in the range of 70-120% were obtained for 70 (32 by GC/MS, 38 by LC/MS) of 113 pesticides spiked at 0.1 microg/g into fruits and vegetables. For screening purposes, the method could be appiled to 82 pesticides. Considering the report by Kakimoto et al. in 2004, 177 pesticides were suitable for screening by this method. The limits of detection were 0.001-0.015 microg/g (by GC/MS) and < 0.001-0.010 microg/g (by LC/MS). The calibration curves were linear for most pesticides, with correlation coefficients of 0.976-1.000 (by GC/MS) and 0.968-1.000 (by LC/MS). The values obtained for fruits and vegetables naturally contaminated with pesticides by this method were nearly equal to those by the official method.
