AVALIACAO DA CONTAMINACAO DE METAIS EM SEDIMENTOS SUPERFICIAIS DAS PRAIAS DO LAGO DE ITAIPU

摘要

This work was performed to evaluate the distribution of metals Al, Cd, Cr, Cu, Fe, Mn, Ni, Pb and Zn in the sediment surface in the ltaipu Lake-PR-Brazil. It was also performed to measurement the pH, phosphorus, organic carbon and particle size. In accordance of international criteria of quality of sediment, the results indicate an anthropogenic collaborations since some metals reached an excessive values. The factor of contamination was also used to evaluate the levels of contamination. The levels of Cu and Ph indicate a moderate contamination, so that it's possible to do harm to the balance of the ecosystem studied.
