Establishing of monitoring network on Kosovo rivers (Drini i Bardhë, Morava e Binçës, Lepenc and Sitnica)

The main goal of this work was to establish a monitoring network on main rivers of Kosovo. We aim to apply WFD (Water Framework Directive) in Kosovo as soon as possible, and our research could be the first step towards it. Waters of the rivers Drini i Bardhë, Morava e Binçës, Lepenc and Sitnica, which are of supra-regional interest, are investigated systematically. Statistical methods are applied to find locations where integrated water resources management can be suggested. Sediments of these rivers were also investigated at the same monitoring points and results have recently been published by us. In this paper we present results of mass concentrations of ecotoxic metals: Cu(II), Pb(II), Cd(II), Zn(II) and Mn(II) in waters of four main rivers of Kosovo. Results of anomalous concentrations of ecotoxic metals in water are compared with anomalous concentrations of the same elements found in sediments. In Drini i Bardhë River the only anomalous value (for Mn) was found in sediment. In Morava e Binçës extreme values of Cd were found in sediments at the lower stretch of the river. In water anomalous values of Cd, Cu and Mn were found at the upper stretch of the river, which are above permanent toxic values. In Lepenc River anomalies were not found, indicating uncontaminated river. Sitnica River is still polluted at two locations, although most of the industry is closed. Anomalous values of Cd, Pb and Zn were found in sediments and of Pb in water at location S2 (Fushë Kosovë) ; at location S5 (Mitrovicë) anomalous values of Cu, Cd, Pb and Zn were found in sediments and of Cd and Zn in water. Continuation of water and sediment monitoring by Kosovo authorities is highly recommended. Possible remediation at critical locations on Sitnica and Morava e Binçës rivers would be desirable.
