Caracterização dos Parâmetros de Qualidade de Água do Rio Aurá, Belém-Pará: Aplicação de Índice de Qualidade Malasiano (DOE-IQA). 2019. 99 f. Dissertação (Mestrado em Engenharia de Processos) – Instituto de Tecnologia, Universidade Federal do Pará, Belém, 2019.https://rigalileo.itegam.org.br/handle/123456789/827The 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.pdf.Qualidade da águaRio AuráÍndice de Qualidade Malasiano (DOE-IQA)Poluição hídricaCONAMA 357/2005DissertaçãoEngenharia Sanitária
