Tracing the spatial distribution and mobility of metal/metalloid contaminants in Oxisols in the vicinity of the Nkana copper smelter, Copperbelt province, Zambia

Popis výsledku v původním jazyce

Topsoils in the vicinity of the Nkana copper smelter were studied in order to assess the spatial distribution of metal/metalloid contaminants (As, Co, Cu, Pb, Zn) around the smelter. The bulk concentrations of metal/metalloid contaminants were determinedby ICP techniques, supplemented by the determination of the Pb isotopic composition of selected samples measured by quadrupole-based ICP-MS. The spatial distribution of the major contaminants indicated the highest contamination NW of the smelter stack,corresponding to the prevailing wind direction in the area. Lead isotopes helped to differentiate the extent of metallic pollution and indicated the mixing of three major pollution sources: smelting activities, petrol combustion and regional background.To assess the vertical mobility of inorganic contaminants, a 110-cm-deep profile in Oxisol in a highly polluted zone in the near vicinity of the Nkana smelter was sampled and studied by combination of bulk chemical analysis, sequential ex
