Sažetak
In Kosovo, the supply of potable water from water sources is represented by about 40%. This study represents the geochemical analyses of sediments, spatial and statistical analyses of major elements in sediments (fraction <63 iim) of water sources in Drini i Bardhe river basin. For better understanding of geochemical consistence of sediments ICP-MS was used and the amounts of P and S were determined by ICP-OES. By comparing the concentrations of Ba. Se and P elements with the existing criteria, it was found that 26 from 50 sample points exceed recommended norms, that cause low/significant toxic effects and 23 from 50 sample points include anomalies of analysed elements. In terms of statistical interpretation the average concentration of the studied elements have decreased in such order: Ca>A1>Mg>K>S>P>Na>Ba>Sr>Li> Rb>B>Ga>Cs>Be>Se. In terms of correlation analyses elements such as: Li. Be, Mg, P and Ba did not show significant positive correlation with any element. Cluster analysis of R-modality show a branch of dendogram linked with Ca. Al. Mg. S, K, P. Na, Ba, Sr, Cs, B, Ga, Se, Be, Rb and Li. Spatial distribution maps of major elements show that high concentration of Li, Ca and Ba were located mostly in the north part. high concentrations of B, Na, Mg, Sr and Cs were located in the north-east part, high concentrations of Be and Al were located in the north and south part and high concentrations of P, S, K and Rb were located mostly in the south-east part of the catchment basin. This high concentration of elements is impacted by the lithology of rocks and from minor influence of human activity (the case of P).
