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