摘要：Sequential extraction method allows determination of metals from operationally defined fractions: ionic exchangeable fraction, fraction adsorbed onto iron and manganese oxyhydroxide surfaces, fraction linked by organic matter and that linked by mineral networks. The analysis of metals distribution in fractions of a waste mining deposit and in zones covered with soils cultivated with grass plants, showed a change of concentrations in operationally defined fractions. Changes depend on both metal type and grass plant. In case of iron, copper and zinc, accumulation processes were recorded in zones cultivated with grass plants.
