STUDY OF CHROME ON WATER AND SEDIMENTS OF RIVERS LOCATED IN BRAZILIAN AMAZON REGION

STUDY OF CHROME ON WATER AND SEDIMENTS OF RIVERS LOCATED IN BRAZILIAN AMAZON REGION

The process of treatment of liquid waste employed by Tannery Tocantins is the chemical precipitation method, however this method has limited metal removal capability, especially potentially toxic metals contained in the liquid waste. Given the complexity of the problem, this research science seeks to determine, through quantitative analysis, the concentration of potentially toxic metal, chrome, in water and sediments in the No Name stream that receives the liquid waste from tannery industry in the city of Governor Edison Lobão and in the Posse stream which is a tributary of the river Campo Alegre. The determination of potentially toxic metals, collected in five (5) sampling points and periods of dry and rainy seasons, were made by spectrophotometry and physical and chemical parameters: pH, turbidity and electrical conductivity. The results showed significant variations in metal concentrations investigated denoting anthropogenic character input associated with the lithology of the region, which together with point sources contribute to the deterioration of surface water of water bodies studied here.Key words: contamination; water bodies; tanning; chromium salts; sediments.

Consciente da complexidade do problema, este trabalho de pesquisa cientifica visa determinar, através de análises quantitativas, a concentração desse metal potencialmente tóxico, cromo, em águas e sedimentos no córrego Sem Nome que recebe os resíduos líquidos da Indústria de curtume do município de Governador Edison Lobão e no córrego Posse que é um afluente do rio Campo Alegre. As determinações dos metais potencialmente tóxicos, coletados em 5 (cinco) pontos de amostragem e em períodos de estiagem e chuvoso, foram feitas por meio de espectrofotometria e parâmetros físicos e químicos: pH, turbidez, e condutividade elétrica. Os resultados obtidos evidenciaram variações significativas das concentrações do metal investigado denotando uma contribuição de caráter antropogênico associada à litologia da região, o que juntamente com fontes pontuais contribuem para a deterioração das águas superficiais dos corpos hídricos aqui estudados.Palavras chaves: contaminação; corpos hídricos; curtume; sais de cromo; sedimentos.  Instituto de Ingeniería, Universidad Nacional Autónoma de México 2015-12-08 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Artículos evaluados por pares Artículos evaluados por pares Artículos evaluados por pares application/pdf https://www.revistas.unam.mx/index.php/aidis/article/view/53512 Revista AIDIS de Ingeniería y Ciencias Ambientales.
