The effects of Cd, Cu and Zn on the filtration rate of Anodontites trapesialis were tested in order to evaluate the suitability of this freshwater mussel for ecotoxicity bioassays. This sublethal endpoint is very relevant due to the ecological role of this mussel in Amazonian environments. The filtration rates were calculated from the clearance of algae, fed to mussels at different metal concentrations. For all metals clear dose-response relationships were found. Cd exerted the most toxic effects, followed by Cu and Zn. Metal mixtures clearly affected the filtration rates. This fact suggests that A. trapesialis is a suitable ecotoxicological test organism for the Amazonian region.
