Lake Ohrid shows
heavy metal pollution near the sites of the old mines outside Pogradec and this
may be a risk to the creatures living in this part of the lake. In this study,
it was aimed to investigate of some heavy metals (Cr and Ni) concentration in
sediment in the Albanian part of Lake Ohrid and to compare the three sampling
points in the aspect of metal accumulation. Three different stations were
chosen as sampling points: entry of Pogradec town, former factory of ferro
nickel and Lin village. Samples were taken in autumn 2014 and were analyzed
using Atomic Absorption Spectroscopy (AAS). The average concentrations of these
elements were determined. In all stations there were accumulation of Cr and Ni
in sediment and the highest values of two metals (Cr 78.3 ± 26.7
mg/kg, Ni 109.9 ± 26.6 mg/kg) were observed in former factory of ferro nickel
point. With this study we came to conclusion that in this lake has the heavy
metal pollution based on the accumulation of metals in sediment and the part of
lake where was factory of ferro nickel was the most polluted point.
