This paper describes the method for determining 15 individual polychlorinated biphenyls in sediments, using fexIKA extraction. The analytical procedure included extraction and clean-up of extracts with con­centrated sulfuric acid and solid phase extraction (SPE) on Florisil. The identification and quantification of analytes were carried out by capillary gas chromatography (GC) with electron capture detector (ECD) and/or low resolution mass spectrometry (LRMS). The method detection and quantification limits varied from 0.06 to 0.12 and from 0.2 to 0.4 ng/g dry weight, respectively. The relative standard deviations in repeatability and intra-laboratory reproducibility studies varied from 3.2 to 11.2%. Recoveries of analytes from spiked sediment samples were between 74.0% and 108.8%. The method was linear and characterized by good correlation coefficients (>0.99) for all compounds studied. The quality of the method under valida­tion was verified by the analysis of certified reference material and by participation in an interlaboratory exercise.
