Resumo

Iron, Mn, Zn, Cu, Cr, Pb, Ni and Cd, the eight most important metals released into the Paraiba do Sul-Guandu River (PSR-GR) system, were determined in water and suspended particles in order to evaluate their transport and availability to the biota. This river system is the most important source of drinking water for the city of Rio de Janeiro, Brazil. Suspended particles were found to be the main metal transport vehicle. Chromium, Cu, Pb and Zn showed the highest enrichment factors when compared with control areas, while Pb, Mn, Cr and Fe had the highest concentrations in the aqueous phase. Copper, Mn, Zn, Pb, and Fe are the most available metals even when associated with suspended particles.
