Sažetak
In the last twenty years there were two serious incidents in the karstic area of Slovenia and Croatia which resulted in significant amount of PCBs' inflow into the bioecological cycle of the karstic environment. The first one was in Slovenia in the small town Semic, Bela Krajina. Owing to this very high levels of PCBs were observed in nearby samples of air, water, sediment and fish. Even about 2100 km down the river Kupa in Croatia (into which contaminated rivers from Slovenia flowed), levels of PCBs have been higher in comparison with other rivers in Croatia. The second incident was during release of PCBs during war in Croatia. Some natural resources, infrastructure, homes, and enterprises during 1991-1995 warfare in Croatian karst area have been unscrupulously destroyed. During 1996 waste oil and soil samples near damaged transformer stations were collected in Delnice, Zadar, Sibenik, Split, and Dubrovnik area and analysed for polychlorinated biphenyls. Significant levels of PCBs (the highest at the "Bilice" E.T.S. over 2000 mg/kg PCBs in dry soil samples) were found in Sibenik, Zadar and Dubrovnik area. The levels of PCB human intake found in Zadar area are not alarming but should not be under estimated. On the other hand, intake of PCBs in the critical population of Bela Krajina has been very serious.
