摘要：

A new method was developed for the simultaneous analysis of 12 pesticide residues in onion and fennel by gas chromatography(GC)-triple quadrupole mass spectrometry(MS/MS)-electron impact ion source(EI)-select reaction monitoring mode(SRM).The 12 pesticide includes fungicide,acaricide,carbamate and plant growth regulator pesticide.The complicated matrix samples of onion and fennel were extracted by acetonitrile,cleaned up by solid phase extraction of Carb/PSA.By optimizing the GC-MS/MS-SRM parameters,the interference from clean-up procedure was further removed and 12 pesticide residues were determined accurately.The average recoveries for most pesticides(at the spiked level of 0.05-0.20 mg/kg) were between 114%-156%,the relative standard deviation(RSD) of the method was less than 20%,and the limit of detection were 0.5-5 μg/kg.
