AB  - Although toxaphene is now banned in use, the analysis of toxaphene has attracted 
      increasing interest due to its persistence and widespread atmospheric transport 
      in the environment. A new method based on isotope dilution-gas 
      chromatography-tandem mass spectrometry (ID-GC-MS/MS) has been developed for the 
      determination of three toxaphene specific congeners comprised of Parlar No. 26 
      (P26), Parlar No. 50 (P50) and Parlar No. 62 (P62) in soil. (13)C10-labeled 
      indicator toxaphene solution was added to the sample prior to pretreatment. Then 
      the sample was extracted using pressurized liquid extraction (PLE) followed by 
      purification on multilayer acidic silica column and neutral silica column. The 
      eluent was concentrated under gentle nitrogen gas flow and spiked with the 
      injection of internal standard of (13)C10-chlordane. Identification and 
      quantification of the analytes were carried out in the multiple reaction 
      monitoring (MRM) mode after the GC separation. The linear range was 20-800 
      microg/L for three congeners, limits of detection (LOD) ranged from 3.0 to 6.0 
      pg. The five point calibration curves showed a good linearity for all the 
      congeners (R2 > 0.99). The relative standard deviations (RSDs) were below 11% for 
      and the spiked recoveries were in the range of 55%-110%. The developed analytical 
      method is suitable for the determination of toxaphene specific congeners in soil.
