In Kosovo, the current production of electricity depends mainly on its generation, which is based on the burning of lignite in the power plants (Kosovo power plants A and B). Significant changes were found in the concentrations of heavy metals in various sediment, soil, and water sample locations. Physicochemical parameters such as temperature, pH, dissolved oxygen, chemical oxygen demand, total dissolved solids, biochemical oxygen demand, and main ions (SO42-, PO43-, Cl-, NO3-, and NH4+) were monitored to obtain accurate and representative data. The study indicates that there is mild contamination from these elements in the river, however, to reach a clear conclusion, additional research should be done in the study area. The sampling took place over three months in 2018 (April, July and October). The data analysis revealed that the concentration of heavy metals such as Pb, Zn, Fe, Ni, Cd, Mn, Al, Cu, and Cr in several examined samples exceeds the maximum permissible limits. Substantial levels of metal pollution in the samples collected in three distinct locations were found.

The environment and its components have been severely contaminated over the years due to massive pollution. The multiple use of heavy metals in industrial, domestic, agricultural, medical and technological applications have led to their wide distribution in the environment. Different studies implied that the primary contribution to the ecological risk index, originated from various anthropogenic influences such as industrialization and urbanization. This has compromised the ability of the environment to foster life and render its intrinsic values due to the heavy usage of these elements. This research illustrates the assessment of heavy metals in waste, water, sludge and soil. Monitoring was performed in vicinity of a cement factory on the southern Kosovo, where the sampling and measurements were performed in the autumn season of 2018. With the use of atomic absorption spectroscopy technique (AAS), the elements determined in this study were Pb, Zn, Cu, Ni, Fe, Mn, and Al. The findings of this study revealed a little change in the concentrations of these elements in the environment samples, especially in water, apart from that there is slight pollution of the environment with heavy metals in this zone.
