Opis:: The pollution of rivers is an important issue because the utilization of polluted water has a direct effect on the health of people and other living beings, economy, etc. Sediments represent a very suitable indicator for monitoring and detecting pollution sources of river waters. The aim of this study is to analyze the contents of selected metals in the sediments of the rivers Likova, Kumanova and Pçinja rivers. The water samples were taken in June 2014 from six sampling stations. Several physicochemical parameters of rivers were determined and the contents of twenty-two metals was indicated in the sediment samples taken from these rivers. The obtained physico-chemical quality of the water from these rivers resulted in classification to the first/second category. The sediments were mostly polluted by Al, Ca, Na and Mg. The metals that exceeded the Dutch standard were: Ba, Ni, Zn, Cr and Cu. The order of metals in sediments was as follows: Fe > Al > Ca > Na > Mg > K > Mn > Ba > Sr > Cr > Zn > V > Ni > Cu > Pb > Li. The study results reveal a mild pollution in rivers caused by urban, agricultural and industrial activities.

Opis:: Water represents an essential element for life and living things on earth. Aquatic ecosystems play a decisive role in the socio-economic development in urban and rural areas. In recent decades, there has been concern at the global level with regard to the deterioration of aquatic ecosystems due to the pollution, which is a product of mainly anthropogenic activity. Heavy metals pollution is worrisome for the ecological balance of the aquatic environment, affecting a variety of organisms. Therefore, the objective of this paper was to characterize the quality of water in the Lepenci River basin, to express heavy metals concentration, and to determine the surface water quality index in this basin. In order to achieve such an objective, water samples were collected at eight stations for analyzing the concentrations for heavy metals. Heavy metals were determined by means of atomic absorption spectrophotometry. A good correlation was found between Pb and Zn (r = 0.84), whereas the average negative correlation coefficient was shown between Mn and Cr (r = -0.6513). The heavy metals concentrations varied from 0.0092 to 0.1135 mg/L.The mean concentrations of heavy metals found in the river water were in the order of: Mn > Fe > Pb > Ni > Cd > Zn > Cr > Cu. The Water Quality Index varied from 57 to 81, with the average value of WQI = 68.1250, which ranks the surface water of this basin as fair. From the results we have concluded that the Lepenci River waters during the monitoring period have had low pollution from heavy metals.

Opis:: The quality of surface waters is being impacted by the anthropogenic and natural pollution, thus limiting the usage of this water for drinking, industry, agriculture, recreation and other purposes. The water quality indices are intended to provide a single value for the water quality of a source or a stream that reduces the large amount of parameters in a simpler expression and enables an easy interpretation of the monitoring data. During 2017, seventeen physicochemical parameters were measured in spring, summer, autumn and winter, in five locations along the Morava e Binçës River in Kosovo. For the assessment we employed the Water Quality Index (WQI) which uses the physicochemical parameters for the evaluation of the water quality. The findings of this study ascertain that MB1 station had the best quality with a value of WQI 88 and is classified in the Good Category, whereas the lowest quality of water was found on in MB4 station with a value of WQI 65 and it is thus classified in the Fair Category. Finally, the average WQI was calculated for the entire measurement period and it resulted in a value of 77.60 indicating that the Morava e Binçës River waters belong to the Fair Category.
