PCB contamination of marine sediment samples in coastal waters of Zadar town, Coatia

In the last twenty years in the karst area of Slovenia and Croatia there were two serious incidents where significant amounts of PCB inflow into the bioecological cycles of the karst environment1. Some natural resources, infrastructure, homes, and enterprises during 1991-1995. warfare in the Croatian karst area has been unscrupulously destroyed. During 1996, waste oil and soil samples near damaged transformer stations were collected in Delnice, Zadar, Šibenik, Split, and Dubrovnik areas and analyzed on PCBs. Significant levels of PCBs (the highest at the “ Bilice” E.T.S. over 2000 mg/kg PCBs in dry soil samples) were found in Šibenik, Zadar and Dubrovnik areas 2. In the period from 1997 to 2007 numerous soil, marine biota and sediment samples were collected from various places in Croatia and Bosnia and analysed for PCBs and DDTs in areas close to the military conflict 3-9. Beside this, various characteristics of sediment samples collected from the Zadar area were also determined10. The aim of this work is to investigate the influence of various soil and sediment characteristics on the level of chlorinated hydrocarbons present in samples.
