Copper isotopic record in soils and tree rings near a copper smelter, Copperbelt, Zambia

Popis výsledku v původním jazyce

The copper (Cu) content and isotopic composition were studied in soils and in pine tree rings at locations close to and far from the Cu smelter, located at Kitwe, Zambia. The soil in the remote area contained 25-75 mg kg(-1) Cu, whereas the soil close to the smelter contained 207-44,000 mg kg(-1) Cu.The delta Cu-65 of the surface soil at both profiles is similar to the isotopic composition of the concentrates processed in the smelter, i.e. both locations are affected by Cu ore dust.The increase in the delta Cu-65 in the direction towards the centre of the profile is caused by the oxidative dissolution of Cu(I) from ore minerals, during which heavier Cu is released. In deeper parts of the profile, there is a slight decrease in delta Cu-65 because of easier mobilisation of the lighter isotope.
