Avaliação do teor de metais em sedimento do rio Betari no Parque Estadual Turístico do Alto Ribeira: PETAR, São Paulo, Brasil
The subsoil of the Vale do Ribeira was the focus of mining industries for the exploration of lead, mainly inside the park - PETAR. Despite the fact that the exploration has ended, the environmental effects of those activities are still present, due to great amounts of heavy metals that are leached. Concentrations of pseudo-total and bioavailable metals were determined in sediment samples of the Betari River, using atomic absorption spectrometry. The results demonstrated that the sediments are contaminated by Pb, Zn and Cu. The findings can contribute to an efficient and environmentally and economically adequate management of the park, for the conservation and the protection of the area.
