Sažetak
In this study, the present status of the transboundary wetlands in Central Europe was evaluated using complementary experimental and statistical methods. Detailed characterization of the complex, subsaline/freshwater system in this study is aimed to be the contribution to the global wetland inventory. The distribution and behaviour of major and trace elements in water from the Neusiedler lake basin (Austria) were investigated. Two water types were proposed: CaNaHCO3 and CaHCO3. Toxic metals were discussed in comparison with the sediment quality criteria and Ni was above the value that might cause severe toxic effects. TOC/TN ratio in sediments suggested terrestrial origin of organic matter. Significant variation of trace elements in water was noticed among the sampling sites. Although the Wulka River was anthropogenically influenced, only dissolved Zn, As and U were above world average values. This was consequence of precipitation and metal adsorption onto suspended particles. Cd, Zn, Mn and Fe were the highest in acidic spring, where low pH maintains metals in a dissolved form. Uranium amounts near closed coalmine exceeded maximum allowed concentration (20 µg L-1). Majority of elements in water and sediment have normal statistical distribution, with a small number of anomalies, thus indicating moderate anthropogenic influence.
