The authors analyzed the physicochemical parameters and heavy metals characterizing the wells at three different sites (nearby villages) in the area of KEC (Kosovo Energetic Corporation). The KEC power plants are the only ones in Kosovo that use fossil-fueled energy (lignite) for the production of the electricity. This process may pollute the environment through the release of airborne aerosols (contaminated with metals), ash (a part of its content that leaches in the underground waters), etc. This pollutes air, surface water, groundwater and soil. In addition, the coal exploitation activity as raw material for power plants, excavating from mining basins, conveyor belt transport, separation before combustion and other processes involving the formation of dust sources and coal particles in the air also contribute to the pollution. Thus, it is of utmost importance to evaluate the water quality of the wells that are used as drinkable water sources by the people that live in this industrial area.

A study investigated physicochemical parameters in environmental matrices along the river Cerica waters. A corre- lation between the actual level of pollution of this river and its impact on the Drini i Bardhë River was determined. The extent of its pollution, was conducted following the identification of pollution sources, which consequently allowing to determine the necessary steps for their isolation. The monitoring of heavy metals, physicochemical parameters, nutrients was carried out in all country-sample (locations). In particular, there where are significant sources of pollution of surface waters, as a result of industrial activities and wastewater discharge. Determining of the locations and heavy metals concentrations was carried out in sediments and agricultural lands in this region, with the purpose to reflect the actual stat.

This study aimed at determining the level of pollution from heavy metals that are deposited from air in the area of Gllogoc. The main goal was to identify the emission sources of pollution by using mosses as bio indicators. In this study area, the mining of Fe-Ni (Industrial Ferronickel Complex) is believed to strongly influence the level of heavy metals. The mining and production activity of Fe-Ni affects the soil, water and air. As the air pollution (from liberated aerosols of Industrial Ferronickel Complex) and the deposition products of this pollution are harmful not only locally but also can pollute the environmental at extended distances, the use of mosses allows analyzing the content and origin of the pollution from heavy metals. ICP was used for the determination of heavy metals in moss samples. The use of Principal Component Analysis (PCA), dendograms and other statistical procedures, permitted to understand the source of the air pollution from heavy metals.
