    Caracterização dos Parâmetros de Qualidade de Água do Rio Aurá, Belém-Pará: Aplicação de Índice de Qualidade Malasiano (DOE-IQA)
    (Instituto de Tecnologia, 2019) RIBEIRO, Arthur Araújo; QUARESMA, Sil Franciley dos Santos
    The study addresses the characterization of the physical-chemical parameters of water quality in the Aurá River, Belém-Pará, using the Malaysian Water Quality Index (DOE-IQA). The study area comprises the upstream region of the Aurá River, where field collections were carried out to determine the physical-chemical variables. The results indicate a direct relationship between population growth and the discharge of pollutants, with significant changes in color, dissolved oxygen, and ammonia nitrogen concentration, above the limits established by CONAMA Resolution 357/2005 for class II waters. The application of the DOE-IQA allowed the identification of the regions most impacted by the discharge and percolation of leachate.
