Tracing the metal dynamics in semi-arid soils near mine tailings using stable Cu and Pb isotopes
Original language description
The dynamics of Cu and Pb were studied in eight soil profiles (Luvisols, Chernozems), located at various distancesfrom the tailing dams near a closed Cu-Pb-(Zn)-Ag mine at Kombat (Namibia) by a combination of isotopeand elemental studies, leaching techniques and speciation modelling. Tailings, soils and bedrocks were analyzedfor the bulk Cu and Pb concentrations, for their chemical forms using the sequential extraction procedure and forthe isotope compositions of Cu (delta65Cu) and Pb (206Pb/207Pb, 208Pb/206Pb).The elemental and isotopic patterns of both contaminated and uncontaminated soil types reflect not only thedistance from the tailing dam but also pedogenetic processes in the profiles and geochemical behaviour of bothcontaminants. The copper elemental and isotope patterns reflect the formation of more mobile species in thesurface environment and movement of solutions and colloids and precipitation onto secondary minerals inLuvisols. Plant uptake of lighter isotopes in Chernozems can influence the Cu isotope patterns in these soil types.The limited movement of colloids and higher sorption capacity of Chernozems is manifested in the isotopecompositions of Cu and Pb in their profiles.
