Abstract

The fast urbanization process associated with the disordered growth produced a continuous and systematic deterioration of natural systems. The trace elements had been used as indicators of these impacts in the environment. This study evaluated trace elements concentrations (Fe, Zn, Mn, Pb, Cu, Cr, Co, Cd e Hg) in bottom surficial sediment of Igarapé (small stream) Tanques that encloses the Porto Velho urban area and municipal waste soil. The results evidenced that the diverse activities developed in investigated areas influenced the trace elements concentrations and limnological characteristics. The principal component analysis to the sediment and soil geochemical variables, demonstrated that the domestic effluents input into igarapé and solid waste inappropriate disposal contributed to trace elements increase. In addition, a trace element input occurs also throughout particles displacement by Fe and Mn oxides.
