Sažetak
Polychlorinated biphenyls (PCBs) are organic compounds exclusively of synthetic origin and one of the most stable organic pollutants. The latest investigations of their harmful influence on biological systems indicate, how the PCBs are one of the most dangerous organic pollutants in environment generally, and especially in water ecosystems. Throughout the passed war, areas of Bosnia and Herzegovina and Kosovo have been jeopardized with the formation of dangerous wastes. In the frame of international project APOPSBAL, partially financed from European Commission, investigation the contamination of river sediments with PCBs in these areas have been carried out. Co-workers from Geological survey Sarajevo and Faculty of science Prishtina have suggested the sampling locations for which exist indications for the spilling of these very dangerous and stable organic pollutants into the environment. Collection of sediment samples from Bosnia and Herzegovina and Kosovo local co-workers have performed. Analyses of the samples have been performed in Rudjer Boskovic Institute and in Institute for public health Maribor. Levels of PCBs were determined by capillary gas chromatography with the electron capture detector. Concentrations of PCBs are expressed in ng/g (ppb) of dry sample weight. In a few locations in Bosnia and Herzegovina has been a determined exceptionally high level of total PCBs (the wellspring-Bihać 882 ppb ; river Miljacka-Sarajevo 1654 ppb ; in the region of town Tuzla rivers: Gostilja 2766 ppb, Oskova 1513 ppb, Jala 2048 ppb, Spreča 2257 ppb). The most probable origin of these contaminations is vicinity to the spots where the oil leaking from damaged capacitors has been observed, vicinity of coal mines, industrial areas and places of waste water spilling over, and also damaged military relays. Research of PCB pollution in areas of Kosovo has not been extensive as in Bosnia and Herzegovina. Analyses of sediments were performed in following locations: river Ibar-Mitrovica, river Ibar-Obilić and Plemetin, and also the mud of waste water TE Kosovo B. In these sediment samples obtained range of PCB levels has been from 18 to 248 ppb.
