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

Abstract: 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 … Show more

“…The occurrence of Cd only in the months of January and February in P3 may be associated with the exploitation of industrial sand and gravel in Pedreira Pedra Sul or the excessive use of fertilizers (Benson et al, 2014;Balkhair and Ashraf, 2016) in agricultural activities that also occur in this sub-basin. Cd contamination was not associated with the domestic sewage discharge because it was not seen in P1 and had not been continuously detected in other months, considering that domestic sewage is continuously released.…”

“…Oliveira and Pasqual (2004), Lopes et al (2007) and Nakamura et al (2014), verified the contamination of the water table by heavy metals in their stidies. Arsenic, Cadmium, Lead, Copper, Mercury and Zinc are systematically referred to as sources of urban waste deposited in landfills or dumps, domestic sewage, mining, industrial dumping and agricultural activities (Campos et al, 2009;Coelho, 2012;Cotta et al, 2006;Egreja Filho et al, 1999;Jesus et al, 2004;Lima and Santos, 2012;Macêdo, 2007;Marins et al, 2004;Nakamura et al, 2014;Nriagu e Pacyna, 1988;Ribeiro et al, 2012;Santana and Barroncas, 2007;Silva et al, 2016;WHO, 2004;2007;2010a;2010b;2010c;Yu et al, 2014).…”

“…A presença de elementos potencialmente tóxicos é responsável por efeitos adversos no ambiente, com repercussão direta na saúde pública. A introdução de metais potencialmente tóxicos nos sistemas aquáticos e em outros compartimentos ambientais ocorre naturalmente, por meio de processos geoquímicos e no intemperismo; a contribuição decorrente da atividade humana é um reflexo de sua ampla utilização pela indústria (CAMPOS et al, 2009).…”
