AB  - A high performance gas chromatography-mass spectrometry (GC-MS) method for the 
      determination of 25 organochlorine pesticides in tea has been developed. The 
      samples of tea were extracted with n-hexane-acetone (2: 1, v/v). The extract was 
      purified by using a Florisil column with n-hexane-ethyl acetate (9: 1, v/v) as 
      elution solvent. Chromatographic analysis was performed on a DB-35MS capillary 
      column. Satisfactory separation and sensitivity of 25 organochlorine pesticides 
      were obtained with the proposed method. The analytical results show the working 
      curves for 25 organochlorine pesticides were linear in the range of 0.010 - 0.500 
      mg/L by GC-MS on selective ion monitoring mode. The recoveries of 25 
      organochlorine pesticides at spiked levels of 0.01 -0.20 mg/kg were 70.8% - 
      105.5%, and relative standard deviations (RSDs) were 1.6% - 12.7%. The limits of 
      quantitation were 0.01 mg/kg except that for endosulfan I and endosulfan II that 
      were 0.02 mg/kg.
