AB  - OBJECTIVE: A method for the determination of 41 pesticides including 26 
      organophosphorus pesticides, 6 kinds of carbamate, 7 pryethoids insecticides, 1 
      kinds of organochlorine and fungicide in vegetables and fruits, was established 
      based on optimized QuEChERS with on line gel permeation chromatography-gas 
      chromatography-mass spectrometry (GPC-GC-MS/MS). METHODS: The method obtained the 
      optimized conditions by comparing different methods of extraction and 
      purification. The analytes were extracted from the samples using 
      acetonitrile-buffer of acetic acid and sodium acetate. Then the extracts were 
      determined by GC-MS/MS in multireaction monitoring (MRM) mode after being cleaned 
      up with mixed solid-phase dispersion. And the external standard method was 
      applied to quantify. RESULTS: All the 41 pesticides had good linearity in the 
      ranges of 2-200 ng/mL with the correlation coefficients higher than 0.995. The 
      average recoveries of the most of 41 pesticides in celery and apple were in the 
      range of 71.0%-125.4% at the spiked levels of 5, 10 and 50 mug/kg,with relative 
      standard deviations (RSDs) of 0.34%-15.0%. The limits of quantification (LOQs) of 
      the method at the spiked levels of 5 mug/kg were 0.107-10.100 mug/kg. CONCLUSION: 
      The method is simple, rapid, sensitive and specific.
