Sažetak
Spatial distribution of five ecotoxic trace metals (Cd, Cu, Pb, Zn and Hg) in waters of "Plitvice Lakes" National park sampled during the year of 2005 and 2006 was studied. Water samples were taken at several locations in the National Park (17 sampling sites). Cd, Cu, Pb and Zn concentrations were determined using differential pulse anodic stripping voltammetry (DPASV), while cold vapor atomic absorption spectrometry (CVAAS) was used for mercury determination. The measured concentrations of all trace metals were very low, and comparable with the concentrations obtained in unpolluted waters of other protected areas. Slightly higher concentrations of zinc and cadmium found in the "Bijela rijeka" river most likely originate from the Mesozoic dolomite. According to the water quality criteria established by the corresponding regulations of the Republic Croatia, and also according to the metal concentration parameter, the waters of National park belong to the "I class" waters.
