AB  - A multi-residue method for the determination of 88 pesticides in tea using gas 
      chromatography-tandem mass spectrometry (GC-MS/MS) was developed. The target 
      compounds were extracted with acetonitrile by accelerated solvent extraction 
      (ASE), and the extracts were cleaned up by solid phase extraction (SPE) with a 
      Carbon/NH2 cartridge and eluted with acetonitrile-toluene (3:1, v/v) before the 
      identification and quantification of the residues by GC-MS/MS. Performance 
      characteristics, such as accuracy, precision, linear range, limits of detection 
      (LODs) and limits of quantification (LOQs), for each pesticide were determined. 
      At low concentration level spiked (6.4 microg/kg), the average recoveries were in 
      the range of 70%-100% for 87.5% analytes and the relative standard deviations 
      (RSDs) were lower than 15% for 87.5% analytes. The quantification of analytes was 
      carried out using the most sensitive transition for every compound and by 
      matrix-matched standards calibration. The LOQs (S/N = 10) were less than 10 
      microg/kg for 86.4% analytes. The method is sensitive, accurate, reliable and 
      suitable for the simultaneous determination of multi-residue pesticides in green 
      tea, Woolong tea, black tea and Puer tea.
