Abstract
The concentrations of the 24 elements (Al, As, Ba, Ca, Cd, Co, Cu, Fe, K, Li, Mg, Mn, Na, Ni, P, Pb, Rb, Sb, Sc, Sr, Ti, V, Y and Zn) were determined in the water samples from river Bregalnica and its tributaries. Inductively coupled plasma -mass spectrometry (ICP-MS) was applied as quantification method. It was found that due to the pollution from Pb-Zn mine “Sasa” the concentration of Zn (664 µg L-1) and Pb (45 µg L-1) in the water from Kamenichka River exceeded the maximum allowed concentrations in accordance to the national regulation for surface water quality. Significant deviation in the Fe, Pb, Sb and Zn concentrations were determined along the river Bregalnica, from the river source to the estuary in the river Vardar. The multivariate processing singled out three dominant geochemical associations in the river waters from the Bregalnica River Basin: F1 (Ca-K-Mg-Na-Ba-Li-Mn-Sr-V), F2 (Al-Fe) and F3 (Sb) with the total variability 80.6%.
