【 摘 要 】

Bioaccumulation of Ag, Al, Cd, Co, Cr, Cu, Fe, Mn, Ni, Pb and Zn was determined in the gills and liver of Cyprinus carpio and related to concentrations in the sediment and water of the Alagados Reservoir, Ponta Grossa/Paraná. Cd and Fe exceeded the legal limit for water. Fe was the most abundant metal in the reservoir's water and sediment. The metals in the sediment were below the level of probable adverse effects on biota. There were no significant differences between sampling sites for water and sediment. Liver and gills had higher concentrations of Al, Fe and Zn, with a significant increase in Al (P > 0.05) compared to the increase in weight and size of the specimens. Statistically, gills showed higher concentrations of Al, Cd, Co, Cr, Mn and Zn and liver higher concentrations of Cu and Fe. Co, Cu, Fe, Mn and Zn showed significant differences (P < 0.01) between the organs. The bioaccumulation factors (BAF) showed that the interaction of water with gills promotes greater accumulation of metals in this organ. Despite the low concentrations in the reservoir, bioaccumulation of metals in gills and liver of C. carpio occurs by its interaction with contaminated water and sediment, respectively.
