Resumo

DectectIoN oF coNtAMINANtS IN A BIoINDIcAtoR SPecIeS (Corbicula fluminea) -RIBeIRA De IGUAPe RIVeR, SAo PAULo StAte. the study assessed heavy metal concentrations in the tissue samples of Corbicula fluminea, by IcP-oeS.In the tissues, average levels of 23.99 µg/g of cu, 144.21 µg/g of Zn, 0.71 µg/g of cd, 7.10 µg/g of cr and 2.41 µg/g of Pb were detected ahowing that this last value is high and above the ANVISA reference (2.00 µg/g) for fish and other products.the results suggest that natural processes occuring in the Ribeira de Iguape River are not sufficient for purification so that metals remain in the water and can accumulate in the trophic chain.
