Resumo: | The interaction between heavy metals and soil constituents is one of the most important factors influencing the potential for ground water pollution. To study Pb behavior, samples of soils were incubated with a salt solution containing this metal. The experimental units consisted of plastic bags, partially opened with 0.1 dm³ of soil with three replications. After incubation, samples were subjected to sequential and selective extractions. Lead retention, measured by the maximum adsorption capacity of the soil, was relatively high with values ranging from 6,439 to 22,148 mg kg-1. The sequential and selective extractions showed that Pb adsorption was stable where the metal was found mainly in organic matter, Fe and Al oxides, and residual forms (specific adsorption). The capacity of the soils to retain Pb, thereby increasing the leaching potential of the metal, was in the sequence of: Histosol - Oxisol - Inceptisol. |
