Sažetak
During the recent war, the karst area of Croatia has been jeopardized by hazardous waste and deserves particular attention because of its exceptional ecological sensitivity and unfortunately unscrupulous destruction of natural resources, infrastructure, homes and enterprises. There are great fears and concrete evidence those significant quantities of polychlorinated biphenyls (PCB) ; various flame-retardants, explosives, and their by-products were released in the environment during warfare. During 1996. waste oil and soil samples near damaged transformer stations were collected in Delnice, Zadar, Šibenik, Split, and Dubrovnik area and analyzed on polychlorinated biphenyls. Shown results do not indicate significant contamination of soil with polychlorinated biphenyls in the transformer station or in oil taken from the oil trench TS "Delnice" and TS "Split". Concerning the distance from the capacitor battery hit by a rocket fire at transformer installation in Komolac near Dubrovnik, soil showed significant levels of polychlorinated biphenyls. PCB levels indicate significant soil contamination below the capacitor battery hit by a rocket fire in the area of transformer station TS 220/110/30 kV "Bilice", Šibenik. Results of the analysis of polychlorinated biphenyls in soil from four locations (on some locations, on two depths), indicate significant contamination of the investigated area TS 110/35 kV - Zadar. It was reason for thoroughly investigation this site for levels of PCBs in soil samples around damaged capacitor. An air dried soil samples were extracted 24 hours with n-hexane by Soxhlet extraction. The analytical method used for the analysis of extracts included filtration through a column of Na_2SO-4 anh. cleaning on an alumina column and the separation of the PCB's from organochlorine insecticides on a miniature silica gel column. After concentration down from 0.3 to 1 cm^-3, elutes were analyzed by EC gas chromatography. During all the analytical procedures, the Mirex standard was used as the internal standard. Results of the analysis on PCB in soil from TS "Zadar" indicate significant contamination of the area with polychlorinated biphenyls. Comparing the given levels of PCB in soil from TS "Zadar" and, by the tolerance criteria accepted in the Netherlands, levels of contamination on some locations far exceed the tolerant levels that do not require remediation (for more than two hundred times).
