Distribution of PCBs in sediments of the Červený potok, stream contamined by technical PCB mixtures Delor, Czech Republic

Original language description

The results of measurement of PCBs in sediments contaminated by technical PCB mixtures Delor collected from the Červený potok (Litavka River catchment), Czech Republic are presented. The sediment samples of two different grain size fractions (< 2 mm and< 200 ?m) were analyzed for 8 congeners of PCBs using Soxhlet extraction and GC-ECD. Total concentrations of PCBs ranged from 15.3 to 997 ng g-1 in < 2 mm fraction and from 29.9 to 952 ng g-1 in < 200 ?m fraction, where PCBs 28, 52, 101, 138, 153, 180 and 194 were found in all the samples. The highest levels of PCBs were found in sediment below the discharge of municipal wastewater treatment plant and local engineering industry in the Komárov village. High percentage of PCBs 28, 153 and 138 (22?74%, 5?22% and 5?20% respectively) indicates the contamination by PCBs mixtures Delor 103 and Delor 105. The result of PCA analysis indicates that the more highly chlorinated PCB congeners were more associated with finer organic carbon particles.
