AB  - The paper is to report the establishment of a method for the determination of 
      multi-residue organochlorine and pyrethroid pesticides in traditional Chinese 
      medicines (TCMs). Fifty-six pesticides were extracted by high-speed 
      homogenization, and then purified through gel permeation chromatography (GPC) and 
      solid phase extraction (SPE) cartridges. The residues were simultaneously 
      identified and quantified by GC-ECD equipped with dual tower, dual column and two 
      micro-ECD detectors. The analytical performance was demonstrated by the analysis 
      of 3 TCMs samples' extracts, spiked at three concentration levels for each 
      pesticide. In general, the recoveries ranging from 70% to 110%, with relative 
      standard deviations (RSDs) better than 15%, were obtained. The limit of detection 
      (LOD) for most of the targeted pesticides tested was below 0.01 mg kg(-1). The 
      method had good extraction efficiency, purification effect and good 
      reproducibility, which could be applied to the determination of organochlorine 
      and pyrethroid pesticide residues in the routine analysis of TCMs.
