Bioacumulação de metais pesados e nutrientes no mexilhão dourado do reservatório da Usina Hidrelétrica de Itaipu Binacional

This study aims to evaluate the bioaccumulation of macronutrients and heavy metals in the golden mussel according to its collection site and seasonality in the aquaculture area of the reservoir from April/2009 to March/2010. There is no difference (p &gt; 0.05) in the concentration of metals with respect to the point of collection. The concentrations of Cu, Fe, Mn, Zn, Cd and Pb were higher (p < 0.05) in spring and summer than in fall and winter. Values of the heavy-metal pollution index (MPI) for collection point and seasonality indicate environmental contamination in the aquaculture area.
