Discrimination of lithogenic and anthropogenic sources of metals and sulfur in soils of the Zambian Copperbelt: A topsoil vs. subsurface soil concept and factor analysis

Popis výsledku v původním jazyce

Abstract. To distinguish lithogenic sources of metals from anthropogenic contamination of soils caused by fallout of dust from mining operations, flotation tailing dams and smelters, sampling of topsoils together with reference sampling of subsurface soils from the depth of 80?90 cm was carried out over an area of 4 700 km2. The total sulfur (Stot), Cu and Co contents were found to be significantly higher in topsoil relative to subsurface soil over a large part of the surveyed area, and Zn, Pb, As and Hg contents showed a definite increase in the close neighbourhood of smelters. In contrast, the concentrations of characteristic lithogenic elements such as Cr, Ni and V, that show a direct correlation with the content of iron, increase in the subsurfacesoil relative to topsoil.
