摘要

Skadar lake is the biggest, and the most important, aquatic catchment in Montenegro. The main inflow to the lake (from Montenegro) are the Moraca and Crnojevica Rivers. These rivers flow through industrial and urban settlements, which may ultimately result in pollution of lake water. The objective of this study was to provide more detailed information on the eco-chemical properties of the lake system through measurement of metal concentrations and the role of sediment - water inter-reaction in controlling their distribution. The factors that impact metal concentrations in sediments of shore waters are alochthonous influences (natural effects and civilization effects) and autochthonous influences (settlement mechanism and sorption processes), as well as transformation of elements in settled sediments. Sediments and water samples were taken from 15 sites and analysed for iron (Fe), copper (Cu), zinc (Zn), cadmium (Cd) and lead (Pb).rnThe results indicate similarities of mechanisms of metal distributions between extracted phases of sediment, and also suggest that the overall aquatic ecosystem of the lake is still in a relatively pristine state. Distribution of examined metals in appropriate phases shows very low presence of anthropogenic fraction, while ecochemically least important, fifth phase, is most abundant. After comparison with US EPA (2002): ,,A guidance manual to support the assessment of contaminated sediments in freshwater ecosystems", it was confirmed that concentrations of metals found do not endanger life in Skadar lake.
