A simple sample-pretreatment method was developed for GC/MS analysis of chlordanes residues in river sediments. The method is composed of three steps, i.e., (1) extraction in a 10-ml test tube, (2) clean-up with a micro silica gel column, and (3) concentration by micro-evaporation. Both clean-up and concentration were carried out using a capillary pasteur pipette. The chlordanes was extracted from 1 g of the sediment and was concentrated to 2030 μl as a sample solution. The contents was determined by injecting a sample solution onto GC/MS. The total concentration of trans-γ-chlordane and cis-α-chlordane was determined by selected ion monitoring (m/z 375). The recovery of the standard trans-chlordane was estimated to be about 50%. The detection limit of the trans-chlordane was 3 pg. The present method is enough sensitive to detect ppt to ppb levels of chlordanes residues in river sediments.
