PG  - 773-80
AB  - Gas chromatography (GC) coupled with dual columns and dual electron capture 
      detectors (ECD) was established to determine 23 organochlorine pesticides in 5 
      soil and 5 sediment samples. Microwave assisted extraction and solid phase 
      extraction with a Florisil column and sulfur cleanup with copper powder were used 
      in sample pre-processing. Chromatographic analysis was performed on DB-XLB and 
      DB-1701 capillary columns by internal standard method. This method showed good 
      extraction efficiency, high sensitivity and good reproducibility. In the same 
      linear range of 0.005 - 0.5 mg/L of 23 pesticides, the correlation coefficients 
      were higher than 0.997. The average spiked recoveries were 50% - 119% with the 
      relative standard deviations (RSDs) of 0.9% - 16.1% (n = 6) in 5 soil samples, 
      and were 52% - 120% with RSDs of 0.3% - 28.4% ( n = 6) in 5 sediment samples, 
      respectively. The detection limits were 0.000 05 -0.000 5 mg/kg. The results 
      indicate that this method is suitable for the determination of the 23 
      organochlorine pesticides in soil and sediment samples.
