Resumo: The occupation of the banks of urban rivers impacts aquatic environments through the release of effluents and residues, removal of riparian vegetation and changes in the configuration of rivers. With this, this work aimed to carry out the physical-chemical characterization of the Ouricuri river in Capanema, considering the spring area, urban perimeter and mouth, observing the influence of seasonality and urban growth. Temperature (T), pH, dissolved Oxygen (DO) and electrical conductivity (EC) were evaluated. The temperature was higher in the urban area (27.81ºC) in the less rainy season (EMC) and 29.26ºC in the rainy season (EC), influenced by the removal of riparian vegetation. The spring area showed acid pH (N1 = 4.91 and 4.27 in EMC and EC), influenced by the lentic character of the collection points and the contribution of organic matter, the pH was basic in the urban area due to the concentration of domestic effluents in the river. The content of DO was higher in the spring region, (N3 = 3.10 mg/L in EMC and 4.92 mg/L in EC), the parameter decreased in urban areas and mouth, influenced by temperature and decomposition of matter organic. The spring had the lowest EC (N1 = 12.7 µS cm-¹ and 25.3 µS cm-¹ for EMC and EC), and the mouth of the highest levels, EC is influenced by the input of untreated effluents. It was found that the occupation of the banks of the Ouricuri river harms the urban aquatic environment, through changes in the physical environment, which alter the physicochemical variables indicative of water quality.

Con ello, este trabajo tuvo como objetivo realizar la caracterización físico-química del río Ouricuri en Capanema, considerando la zona del manantial, perímetro urbano y desembocadura, observando la influencia de la estacionalidad y el crecimiento urbano. Se evaluaron la temperatura (T), el pH, el oxígeno disuelto (DO) y la conductividad eléctrica (CE). La temperatura fue mayor en el área urbana (27,81ºC) en la época menos lluviosa (EMC) y 29,26ºC en la época lluviosa (CE), influenciada por la remoción de vegetación ribereña. El área de manantial presentó pH ácido (N1 = 4.91 y 4.27 en EMC y EC), influenciado por el carácter léntico de los puntos de captación y el aporte de materia orgánica, el pH fue básico en el área urbana debido a la concentración de efluentes domésticos en el río. El contenido de OD fue mayor en la región de primavera, (N3 = 3.10 mg / L en EMC y 4.92 mg / L en CE), el parámetro disminuyó en áreas urbanas y boca, influenciado por temperatura y descomposición de materia orgánica. El manantial tuvo la CE más baja (N1 = 12,7 µS cm-¹ y 25,3 µS cm-¹ para EMC y EC), y la boca de los niveles más altos, CE está influenciada por la entrada de efluentes no tratados. Se encontró que la ocupación de las riberas del río Ouricuri daña el medio acuático urbano, a través de cambios en el medio físico, que alteran las variables fisicoquímicas indicativas de la calidad del agua.A ocupação das margens dos rios urbanos impacta os ambientes aquáticos através do lançamento de efluentes e resíduos, remoção da vegetação ciliar e mudanças na configuração dos rios. Com isto, este trabalho objetivou realizar a caracterização físico-química do rio Ouricurí em Capanema, considerando a área da nascente, perímetro urbano e foz, observando a influência da sazonalidade e do crescimento urbano. Foram avaliados a Temperatura (T), pH, Oxigênio dissolvido (OD) e Condutividade elétrica (CE). A temperatura foi mais elevada na área urbana (27.81ºC) na estação menos chuvosa (EMC) e 29.26ºC na estação chuvosa (EC), influenciada pela remoção da mata ciliar. A área da nascente apresentou pH ácido (N1 = 4.91 e 4.27 nas EMC e EC), influenciado pelo caráter lêntico dos pontos de coleta e o aporte de matéria orgânica, o pH foi básico na área urbana devido a concentração de efluentes domésticos no rio. O teor de OD foi maior na região da nascente, (N3 = 3,10 mg/L na EMC e 4,92 mg/L na EC), o parâmetro decresceu nas áreas urbana e foz, influenciado pela temperatura e a decomposição da matéria orgânica. A nascente apresentou a menor CE (N1 = 12,7 µS cm-¹ e 25,3 µS cm-¹ para EMC e EC), e a foz níveis mais elevados, a CE é influenciada pelo aporte de efluentes não tratados. Verificou-se que a ocupação das margens do rio Ouricurí prejudica o meio ambiente aquático urbano, através de mudanças no meio físico, que alteram as variáveis físico-químicas indicativas da qualidade da água.Research, Society and Development2021-12-06info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/2286610.33448/rsd-v10i16.22866Research, Society and Development; Vol. 10 No. 16; e51101622866Research, Society and Development; Vol. 10 Núm. 16; e51101622866Research, Society and Development; v. 10 n. 16; e511016228662525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIporhttps://rsdjournal.org/index.php/rsd/article/view/22866/20709Copyright (c) 2021 Eduardo Camurça da Silva; Ana Lúcia Nunes Gutjahr; Carlos Elias de Souza Bragahttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessSilva, Eduardo Camurça da Gutjahr, Ana Lúcia Nunes Braga, Carlos Elias de Souza 2021-12-20T11:03:07Zoai:ojs.pkp.sfu.ca:article/22866Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:41:54.587845Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false
