Manganês, zinco, cádmio, chumbo, mercúrio e crômio no chorume de aterro sanitário em Dourados, MS, Brasil

Abstract: Manganês RESUMONeste estudo analisaram-se as concentrações de manganês, zinco, cádmio, chumbo, mercúrio e crômio, em amostras de chorume coletado no aterro sanitário de Dourados/MS. Foram retiradas amostras de dois reservatórios, um com tratamento aeróbio e outro com tratamento anaeróbio. Foram realizadas quatro coletas de 2012 a 2013, compreendendo períodos de seca e de chuvas. As concentrações dos metais foram determinadas por espectrometria de absorção atômica, modalidade chama. A comparação de resultados e… Show more

“…The electric conductivity (EC) value of the raw leachate sample was 1,562 μS cm -1 (Table 1), double the average found by Riguetti et al (2015), which, when analyzing the toxicity of leachate from a sanitary landfill located in the state of Minas Gerais, Brazil, recorded an EC average of approximately 630 μS cm -1 in a period of one year. High EC indicates a large volume of ions present in the effluent.…”

“…In the raw leachate, these ions are associated with organic and inorganic colloidal particles and in the form of complexes. The reductive conditions of the effluent and the alkaline pH lead to metal ions being complexed in the form of sulfides, sulfates, carbonates and oxyhydroxides and also precipitated in insoluble composites considerably reducing bioavailability of the metals (Riguetti et al, 2015).…”
