dc.description.abstractThe present study presents concentration results for heavy metals, major and trace elements, in two sediment cores collected along the Tietê River: Salto de Itu to Porto Feliz ( Core 4 at point T-5) and Laras to Anhembi (Core 6 at point T18). As, Ba, Br, Co, Cr, Cs, Hf, Rb, Sb, Sc, Ta, Th, U and Zn concentrations by Instrumental Neutron Activation Analysis (INAA) and Al, Ba, Cd, Co, Cr, Cu, Mn, Ni, Pb, Ti, V and Zn concentrations by Inductively Coupled Plasma Optical Emission Spectrometry (ICP OES) were determined. The enrichment factor (EF), to assess the presence of anthropogenic pollution sources, was calculated and showed FE > 1.5 values for As, Br, Cs, Hf, Rb, Ta, Th, U and Zn, confirming the anthropogenic contribution for these elements, in all fractions from both cores. As, Cd, Cr, Cu, Ni, Pb and Zn concentrations were compared to guideline values (TEL and PEL) from the Canadian Council of Ministers of the Environment (CCME) and adopted by the São Paulo State Environmental Company (CETESB) and concentration values between TEL and PEL were found, for all fractions from both cores, presenting good and or regular sediment quality classification, the worst being Core 6.pt_BR
