Abstract
In this paper the results and conclusions from the researches
of the pollution of the water with heavy metals in the drain-basin of Mavrovica
hydro accumulation are given. With our analysis, there is an effort made to
see the real conditions in the exanimated area, and to determine the position
of presence of heavy metals in the water of the above mentioned basin. The
samples of water were taken from river Orelska and the smaller rivers
(streams) near Orelska River. The analyses of the taken samples were made
in the frames of one sequence of analysis of the instrument Atomic emissive
spectrometry, with inductive harnessing plasma (AES-ICP). From the last
examinations of contaminated areas as our area of interest, we can notice
that the following group of elements should be kept track of: Mn, Fe, Al, Pb,
Zn, As, Cd, Cu, Ni, Co, Ag, Cr, Ti with the possibility of several elements that
will show higher concentrations of MAA (maximum allowed amounts).
After the analysis and interpretation of the data, the assumptions were
confirmed for increased values of the following metals: Al, Mn, Fe, Zn, As, Cd,
Cu. The whole drainage system that gravitates trough Orelska river is
contaminated.
Increased concentrations of some of the metals were very often, several times
above the maximum allowed concentrations.
