Resumo
Concentration of metals in 15 bottom sediment samples from Tieteˆ River, a significantly polluted river, were assessed.
Total and partial trace element concentrations were determined, and As, Cd, Cr, Cu, Ni and Zn were found above local
reference values. These metals were also higher than the threshold effect level (TEL) in some sampling points and Zn was
higher than probable effect level (PEL) oriented values in almost all sampling points. The most polluted points were
identified from Tieteˆ to Barra Bonita Counties. Regarding sediment quality, this river is still polluted and precautions to
minimize environmental problems caused by toxic metals to biota and to human health are necessary.
