In this research, we investigated the pollution of heavy metals that is released from power plants of Kosova in two seasons: summer and winter time. The elements that were in focus of the study are: As, Cd, Cr, Co, Fe, Mn, Ni, Pb and Zn. The study was concentrated in Sitnicë River; surface water, groundwater (wells) and soils around the region of TC’’KOSOVA’’. The concentration of metals in the surface water and underground water in the winter season are; Fe 0.19 mg/l, Mn; 0.258 mg/l, Pb; 0.174 mg/l and Zn; 0.238 mg/l. In the summer season, the concentration of heavy metals is increased, especially for; Co, Fe, Mn, Pb and Ni. Based on the results that we obtained, compared with international standards, some of the elements are in high concentration, more than maximum permitted allowed in both seasons, in almost every sampling point. While, metals; Cd and Co, are in permitted levels of concentrations as allowed by international standards.
