Avaliação da contaminação do Igarapé do Sabino (Bacia do Rio Tibiri) por metais pesados, originados dos resíduos e efluentes do Aterro da Ribeira, em São Luís, Maranhão Evaluation of contamination on Sabino streamlet (Basin Rio Tibiri) by heavy metals originated from waste and effluents of the Ribeira landfill, in São Luis island, state of Maranhão, Brazil

<abstract language="eng">This work aimed to carry out an environmental monitoring in sabino narrow river (affluent of Tibiri Basin, in São Luís - MA, Brazil), in order to verify the main environmental impacts caused by effluent residues from Ribeira landfill. Chemical analysis and bibliographic and cartographic researches on this ecosystem were also carried out. In addition, heavy metals, such as Hg, Pb and Zn, were investigated in water samples by ICP-MS technique. It was observed that the contents of such heavy metals were above the tolerance limits established by the Brazilian legislation, showing a strong impact level on the evaluated ecosystem.
