摘要: The distribution and the availability of Cd, Zn, Cu, Pb along entire profile two highly polluted soils located near Zn smelters have been related to chemical mineralogical composition soil. Lead Cu deposits always remain in surface layers their measured by neutral ammonium acetate extraction was very weak. behavior Cd appears different sandy acidic podzolic loamy soils. These metals are associated with organic matter migration soils, while they upper provided that pH is higher than 6. When drops below 6, mobility increases only 5. heavy lower due precipitation carbonates phosphates. With increasing depth, more available if soil acid; but, kept low adsorption on clays free oxides. results complex trace interactions components show a accumulation capacity for notwithstanding fact CEC similar.
