【 摘 要 】

This work was performedto evaluate the distribution of metals Al, Cd, Cr, Cu, Fe, Mn, Ni, Pb and Znin the sediment surface in the Itaipu Lake-PR-Brazil. It was also performedto measurement the pH, phosphorus, organic carbon and particle size. In accordanceof international criteria of quality of sediment, the results indicate an anthropogeniccollaborations since some metals reached an excessive values. The factor ofcontamination was also used to evaluate the levels of contamination. The levelsof Cu and Pb indicate a moderate contamination, so that it's possible to doharm to the balance of the ecosystem studied.
