Metal concentrations in tissue samples were measured by HR-ICPMS. Bivalve tissues exhibited mean levels of 1.00 µg/g Cd; 152.89 µg/g Zn; 14.79 µg/g Cr and 4.40 µg/g Pb. Lead concentrations were comparable to those reported for moderately contaminated sites. The results showed that Pb is bioavailable to the bivalves, exhibiting high concentrations and exceeding both natural and reference values for human consumption. The freshwater bivalve Anodontites tenebricosus is a suitable biomonitor of contamination by metals.454-459porcontaminationRibeira de Iguape RiverAnodontites tenebricosusArtigo10.1590/S0100-40422012000300003S0100-40422012000300003WOS:000303071700003Acesso abertoS0100-40422012000300003.pdf2842419319556542
