ABSTRACT
This paper presents the results of polychlorinated biphenyls (PCBs) determination in
sediments from different sites of the Odra River and its tributaries, collected in 1998-2002.
It was found that concentrations of PCBs varied significantly. The results of individual congeners show
that contents of PCBs 180 and 138 were the highest in the sediments investigated. For better identification
of places most polluted by PCBs, PCB contents on TOC (total organic carbon) basis in surface sediments
are presented.
