Abstract

The present propose evidentiate a detailed study about chemical speciation of the main heavy metals Fe, Mn, Mo, Co, Cr, Cu, Zn, Cd, Ni and Pb in the bottom sediments of the Tietê river (SP) considering these metals distribution in the samples profiles and along the drainage watershed. The selective sequential extraction method is going to be used with seven fractions within the labile phase, in addiction with the residual phase determination, after alkaline fusion of the initial sample. A bottom sediment depth profile sampler, in development phase, is going to be used for bottom sediments sampling in depth profiles along the Tietê river. This procedure is going to proportionate a better understanding about the heavy metals binding in the fluvial environments as well as its mobilizations mechanisms for water courses, under natural or anthropic influence.
