AB  - A method was developed for the determination of chlorpyrifos and its 
      metabolite--3,5,6-trichloro-2-pyridinol (TCP) in vegetables using gas 
      chromatography-tandem mass spectrometry (GC-MS/MS). The sample was extracted with 
      acetone. After the concentration, TCP was derivatized with 
      N-(tert-butyldimethylsilyl) -N-methyltrifluoroacetamide (MTBSTFA). The 
      purification was performed using a florisil solid-phase extraction cartridge. The 
      analyte was detected by triple quadrupole MS in multi-reaction monitoring mode. 
      An internal standard method was used for the quantification of chlorpyrifos, the 
      limit of quantification was 1 microg/kg, and the recoveries were in the range of 
      75.57% - 106.41% with the relative standard deviations (RSDs) of 8.33% - 17.58%. 
      An external standard method was used for the quantification of TCP, the limit of 
      quantification was 0.5 microg/kg, and the recoveries were in the range of 69.11% 
      - 108.43% with the RSDs of 5.20% - 19.42%. The good linear relationships were 
      obtained in the range of 2 - 100 microg/L for the both target analytes. The 
      method can be applied for the determination of chlorpyrifos and its metabolite in 
      vegetables.
