ABSTRACT
The research evaluated the health risks associated with specific heavy metals (Ni, Cr, Pb, Mn, Zn, Cu, Fe, As, Al, Co, Cd) in the surface water of Vasileva Lake, located in the Gllogoc municipality of Kosovo. Surface water and sediment samples were collected in June 2024 and analyzed using inductively coupled plasma optical emission spectrometry (ICP-OES), with results compared to World Health Organization (WHO) and Environmental Protection Agency (EPA) standards.
The average concentrations of heavy metals (mg∙dm−3) in surface water samples were as follows; Zn (2.54), Ni (1.07), Fe (1.03), Mn (0.61), As (0.08), Pb (0.05), Cd (0.009) and Cu (2.41) have high concentration, while the sediment samples concentration is listed (mg∙kg−1) of; Fe (4.67), Zn (4.61), Ni (3.88), Cu (3.22), Pb (2.66), Cr (2.32), As (1.01) and Cd (0.207). The concentrations of contaminants in water samples were higher as compared to concentrations in sediment samples, which were very low. The decreasing trend of the metal levels in surface water and sediment were as follows: Zn > Ni> Fe >Mn >As >Pb >Cd > respectively Fe >Zn >Ni > Cu >Pb >Cr >As >Cd respectively. Correlation analysis indicated significant positive value indicating that the heavy metals were from same source and as well strong negative correlation indicating different source of heavy metals into the lake.
