DISTRIBUTION OF PCBs IN SEDIMENTS OF THE CERVENY POTOK, STREAM CONTAMINATED BY TECHNICAL PCB MIXTURES DELOR, CZECH REPUBLIC
Popis výsledku v původním jazyce
The results of measurement of polychlorinated biphenyls (PCBs) in surface bottom sediments contaminated by technical PCB mixtures Delor collected from the Červený stream (Litavka River catchment), Czech Republic in 2008 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 gas chromatography (GC-ECD). Total concentrations of PCBs ranged between 15.3 and 997 ng g-1 (dry weight) in <2 mm fraction andbetween 29.9 and 952 ng g-1 in <200 ?m 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 Komárov village. High percentage of PCBs 28, 153 and 138 (22-74%, 5-22% and 5-20% respectively) indicate the contamination by PCBs commercial mixtures Delor 103 and Delor 105 (an equi
