"The results of measurement of polychlorinated biphenyls (PCBs) in surface bottom sediments contaminated by technical PCB mixtures Delor collected from the \u010Cerven\u00FD stream (Litavka River catchment), Czech Republic in 2008 are presented. The sediment samples of two different grain size fractions (<2 mm and <200 \u03BCm) were analyzed for 8 congeners of PCBs using Soxhlet extraction and gas chromatography (GC-ECD). Total concentrations of PCBs ranged between 15.3 and 997 ng g-1 (dry weight) in <2 mm fraction and between 29.9 and 952 ng g-1 in <200 \u03BCm fraction, where PCBs 28, 52, 101, 138, 153, 180 and 194 were found in all samples. Results show that the highest level of PCBs was found in sediment collected from area below the discharge of municipal wastewater treatment plant and local engineering industry in Kom\u00E1rov village.
