【 摘 要 】

The subsoil ofthe Vale do Ribeira was the focus of mining industries for the exploration oflead, mainly inside the park - PETAR. Despite the fact that the explorationhas ended, the environmental effects of those activities are still present,due to great amounts of heavy metals that are leached. Concentrations of pseudo-totaland bioavailable metals were determined in sediment samples of the Betari River,using atomic absorption spectrometry. The results demonstrated that the sedimentsare contaminated by Pb, Zn and Cu. The findings can contribute to an efficientand environmentally and economically adequate management of the park, for theconservation and the protection of the area.
