Abstract
The activities of the Sasa mine have led to industrial discharge being released into Lake Kalimanci since the beginning of
mining activity in 1954. For this reason, an ecological risk assessment is urgently required. In the present study, surficial lake sediments
were analyzed using inductively coupled plasma mass spectrometry (ICP-MS), with all geochemistry data processed using Statistica 8.
In order to assess the environmental pollution status, 2 environmental factors were established, while for the determination of chemical
fractionation of toxic metals a sequential extraction procedure was carried out. Concentrations of As, Mo, Zn, Ni, Co, Pb, Cd, and Cu in
surficial Lake Kalimanci sediments were in the ranges of 58.6–77.2, 2.30–4.60, 7056–20,900, 47.4–79.3, 18.8–25.3, 4863–16,300, 46.8–
136, and 328–1162 mg/kg, respectively. Based on values of the enrichment factor and geoaccumulation index, the surficial sediment of
Lake Kalimanci is strongly polluted in terms of most of the examined metals. The results of the sequential extraction procedure revealed
the majority of the investigated toxic metals (Zn, Pb, Ni, Cu, and Cd) to be strongly bonded to the exchangeable fraction and the rest
(As and Mo) to the oxidizable fraction. The geochemistry, environmental factor values, and toxic metal extraction characteristics of Lake
Kalimanci sediments represent a serious environmental risk for an extensive area.
