AB It has studied the fractionation of Fe and several metals in 24 suspended matter samples collected duringtwo cruises in the Ria de Huelva surface water. In all cases are observed high concentrations of Fe (7,4%)and metals. Among metals the most elevated average concentrations correspond to Cu (2834 ppm) followedby Zn (1921 ppm), Pb (344 ppm), As (139 ppm), Cd (22 ppm) and Ni (19 ppm). These high concentrationsmatch with the high amounts of these same elements in surface sediments of this estuarine system and areoriginated by the acid contributions of the Tinto and Odiel rivers. They are observed throughout thesystem, from the mixing zones of both rivers to the interchange channels with the near coast. Thefractionation analysis indicates that an important part of the total concentration of the studied elements isassociated to phases with high chemical mobility, thus, more of 50% of the As, Cd and Pb concentrationspresent in the suspended matter correspond to labiles or very labiles fractions
