Resumo: Due to the constant presence of pollutants in the water bodies and the difficulty of understanding information regarding the condition of the river sediments, the characterization of its quality becomes essential. In this way, the objective was to characterize and identify the determinants of the pollution process of the sediments of the Apodi-Mossoró riverbed in the urban stretch of Mossoró-RN. Thirty samples were collected along the course of the Apodi-Mossoró River, within the urban-rural stretch of the municipality of Mossoró. The results of the analysis of the total concentration of the following heavymetals: aluminum (Al), cadmium (Cd), copper (Cu), chromium (Cr), lead (Pb), iron (Fe), manganese (Mn), nickel And zinc (Zn). We applied the multivariate statistical methods of Hierarchical Group Analysis (AAH) and Principal Component Analysis/Factor Analysis (ACP/AF). The distribution of the concentrations of the geochemical parameters in the sediments of the Apodi-Mossoró River were strongly influenced by the characteristics of the collection sites and antropocity. The sampled points were grouped into 4 representative groups regarding the sampling characteristics, identifying possible sites with alterations caused by the anthropic action.

Deste modo, teve-se como objetivo caracterizar e identificar os fatores determinantes sobre o processo de poluição dos sedimentos do leito do rio Apodi-Mossoró no trecho urbano de Mossoró-RN. Foram coletadas 30 amostras ao longo do curso do rio Apodi-Mossoró, dentro do trecho urbano-rural do município de Mossoró. Sendo realizadas análises da concentração total dos seguintes metais pesados: alumínio (Al), cádmio (Cd), cobre (Cu), cromo (Cr), chumbo (Pb), ferro (Fe), manganês (Mn), níquel (Ni) e zinco (Zn). Aplicou-se os métodos estatísticos multivariados de Análise de Agrupamento Hierárquico (AAH) e Análise de Componentes Principais/Análise Fatorial (ACP/AF). A distribuição das concentrações dos parâmetros geoquímicos nos sedimentos do rio Apodi-Mossoró, foram fortemente influenciados pelas características dos locais de coleta e pela antropocidade. Agrupou-se os pontos amostrados em 4 grupos representativos quanto as características de amostragem, identificando possíveis locais com alterações propiciadas pela ação antrópica.Universidade Federal de Uberlândia2018-12-20info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.ufu.br/index.php/sociedadenatureza/article/view/3734910.14393/SN-v30n3-2018-6Sociedade & Natureza; Vol. 30 No. 3 (2018); 108-126Sociedade & Natureza; v. 30 n. 3 (2018); 108-1261982-45130103-1570reponame:Sociedade & natureza (Online)instname:Universidade Federal de Uberlândia (UFU)instacron:UFUporhttps://seer.ufu.br/index.php/sociedadenatureza/article/view/37349/pdfCopyright (c) 2018 Revista Sociedade & Naturezainfo:eu-repo/semantics/openAccessBezerra, Joel MedeirosBatista, Rafael Oliveirada Silva, Paulo Cesar Moura2020-07-03T10:35:35Zoai:ojs.www.seer.ufu.br:article/37349Revistahttp://www.sociedadenatureza.ig.ufu.br/PUBhttps://seer.ufu.br/index.php/sociedadenatureza/oai||sociedade.natureza.ufu@gmail.com|| lucianamelo@ufu.br1982-45130103-1570opendoar:2020-07-03T10:35:35Sociedade & natureza (Online) - Universidade Federal de Uberlândia (UFU)false
