Analysis of Some Environmental Toxic Elements in Water Resources of Kosova

The aim of this paper was to analyse some environmental toxic elements in few water resources of Kosova using Differential Pulse Anodic Striping Voltammetry, DPASV, in universal cell in three electrode system with HDME. Considerable amounts of these environmental toxic elements are continuously emitted in environment from anthropogenic sources. Since the main source for the drinking water, are the rivers that flow within the territory of Kosova, it is of mayor priority the quality of water of these rivers and the water mineral sources.Concentration of Cd2+ ; Pb2+ and Cu2+ ions in all the samples were determined at pH = 1.40 – 2.30 while those of Zn2+ ions at pH 3.7 - 4.2. All the determined parameters with DPASV are compared with the results of ICP/MS method. The mass concentrations of lead and copper ions in the analyzed samples were evidently higher than their natural concentrations levels in these kinds of water, while the zinc and cadmium ions were generally in their natural concentrations levels. Toxic elements results of surface waters are compared with the results of underground waters, with those waters in where there are no anthropogenic effects.
