Ecotoxic Trace Metals in Waters of "Mljet" National Park - Croatia
Spatial and temporal distribution of five ecotoxic trace metals (Cd, Cu, Pb, Zn and Hg) in waters of the “ Mljet” National park during two years period (2005 - 2006), was studied. Obtained concentrations of Cd, Cu, Pb and Zn are presented as dissolved and total fractions and mercury as total. Measurements of Cd, Cu, Pb and Zn concentration levels were performed by differential pulse anodic stripping voltammetry (DPASV), while total mercury by cold vapour atomic absorption spectrometry (CVAAS). Both methods enable measurements of extremely low trace metal concentrations (< 10-8 mol L-1) present in unpolluted waters of the Republic of Croatia. Results suggest complex behaviour of different trace metal species investigated particularly in water columns of saline lakes “ Veliko jezero” and “ Malo jezero” , two main water bodies in the NP “ Mljet” .
