Abstract: Residual amounts of ten carbamate pesticides in vegetables and fruits were determined by LC-MS/MS.Samples of vegetables or fruits were extracted with acetonitrile.Sample solution in CH3OH-CH2Cl2(1+99) was purified by SPE and the eluate,after evaporation to near dryness by N2-blowing and dissolution in 1 mL of acetonitrile,was used for LC-MS/MS determination,with C18 chromatographic column and gradient elution using acetonitrile and methanol-water mixed solution as mobile phase.Detection limits (3S/N) for the 10 pesticides found were 1 μg·kg-1.Recovery of the method was tested at 3 concentration levels of 1,10,100 μg·kg-1 for each of the 10 pesticides,values of recovery found for savoy were ranged from 78.5% to 105.0% and for orange were ranged from 80.3% to 106.0%,with values of RSD′s (n=6) in the ranges of 4.6%-19.8% and 3.5%-17.7% respectively.
