Název v původním jazyce

Surprisingly contrasting metal distribution and fractionation patterns in copper smelter-affected tropical soils in forested and grassland areas (Mufulira, Zambian Copperbelt)

Popis výsledku v původním jazyce

Six soil profiles located near Mufulira (Zambian Copperbelt) were studied to evaluate and compare the extent of environmental pollution of Cu-ore mining and smelting in both forested and grassland areas. The highest metal concentrations were detected inthe uppermost soil layers with the following maxima: Co 45.8 mg kg(-1), Cu 8980 mg kg(-1), Pb 41.6 mg kg(-1), and Zn 97.0 mg kg(-1). Numerous anthropogenic metal-bearing particles were detected in the most polluted soil layers. The spherical smelter-derived particles were mainly composed of covellite (CuS) and chalcocite (Cu2S), while the angular mining-derived particles were mostly composed of chalcopyrite (CuFeS2). Additionally, Fe-Cu oxide particles predominantly corresponding to tenorite (CuO) and delafossite (Cu1+Fe3+O2), along with hydrated Fe-oxides corresponding to secondary weathering products, were detected. In contrast to smelter-affected soils in temperate climates, where forest soils are significantly more enriched in metal
