Abstract
Pollution from mining activities is a significant
problem in several parts of the Republic of Macedonia. A
geochemical study of the surficial sediments of Lake
Kalimanci in the eastern part of the Republic of Macedonia
was carried out to determine their elemental compositions
and to evaluate the pollution status of lake sediments by
employing an enrichment factor (EF). The major and trace
element contamination in surficial lake sediments was
studied to assess the effects of metalliferous mining
activities. The mean concentrations of major elements
(wt%) Si 23.5, Al 7.9, Fe 6.6, Mg 1.3, Ca 3.8, Na 1.1, K
2.3, Ti 0.4, P 0.2, Mn 0.6 and trace elements ranged
within Mo 1.0–4.6 mg/kg, Cu 144.4–1,162 mg/kg, Pb
1,874–16,300 mg/kg, Zn 2,944–20,900 mg/kg, Ni
21.7–79.3 mg/kg, Cd 16.5–136 mg/kg, Sb 0.6–3.6 mg/kg, Bi 3.0–24,3 mg/kg and Ag 1.4–17.3 mg/kg. The
EF ranged within 0.12–590.3. Among which, Cd, Pb, Zn
and As have extremely severe enrichment. The data indicate
that trace elements had extremely high concentrations
in Lake Kalimanci surficial sediments owing to the
anthropogenic addition of contaminants.
