Abstract
This paper examines the impact of high flood magnitude on heavy metal pollution in the Ibar River, northern Kosovo and Metohija. The area of analysis is one of the most important industrial regions of Pb / Zn in Europe. River water samples were taken during and after the flood in January, 2021. Almost all heavy metals cause various cancers and diseases, cumulative effect after prolonged intake through drinking water. The paper provides information on the content of heavy metals in river water used for the treatment of drinking water, as well as the correlation of the proximity of pollution sources and natural floods. Concentrations of toxic elements during and after floods are: lead (Pb) 1502.3 ng/ml (RSD=1.95 %) and 42.95 ng/ml (RSD=0.77%), arsenic (As) 1668.9 ng/ml (RSD=1.50%) and 8.56 ng/ml (RSD=0.29%), cadmium (Cd) 18.87 (RSD=3.52%) ng/ml and 0.062 ng/ml (RSD=2.87%), chromium (Cr) 9.59 ng/ml (RSD=1.49%) and 8.66 ng/ml (RSD=1.54%), mercury (Hg) 37.85 ng/ml (RSD=0.012%) and 13.5 ng/ml (RSD=0.03%), talium (Tl) 0.32 ng/ml (RSD=2.65%) and 0.05 ng/ml(RSD=2.43 %) . The samples were analyzed by ICP – OES (ICP – OES, iCAP 6500 Duo, Thermo Scientific, UK) and ICP - MS (ICP-MS, iCAP Qc, Thermo Scientific, UK) instruments.
