Resumo: | Water is a natural resource indispensable to life, has enormous economic, environmental and social value, and it is fundamental to the survival of humans and ecosystems on our planet. Surface water must meet standards of quality and drinkability, and its physical, chemical and biological characteristics should meet the standards recommended by the World Health Organization. The present study aimed to evaluate the physical-chemical and biological properties of surface water of three water bodies in the Municipality of Teixeira de Freitas, Bahia. The following parameters were evaluated: BOD (Biochemical Oxygen Demand), Total Phosphorus, Total Nitrogen, Dissolved Oxygen, pH, Total Solids, Turbidity and Thermotolerant Coliforms. The evaluation showed that all of the three water bodies are contaminated and in disagreement with the limits established in CONAMA Resolution No. 357/05 for Class 2 freshwater. In addition, one of the three water bodies showed signs of eutrophication. |

As águas superficiais devem atender a padrões de qualidade e potabilidade, sendo que suas características físicas, químicas e biológicas devem estar dentro dos padrões recomendados pela Organização Mundial da Saúde. O presente estudo objetivou avaliar as condições físico-químicas e biológicas da água de superfície de três corpos hídricos no Município de Teixeira de Freitas, Bahia. Foram avaliados os seguintes parâmetros: DBO (Demanda Bioquímica de Oxigênio), Fósforo total, Nitrogênio total, Oxigênio dissolvido, pH, Sólidos Totais, Turbidez e Coliformes Termotolerantes. A avaliação dos três corpos hídricos estudados indicou contaminação das suas águas por estarem em desacordo com os limites estabelecidos na Resolução CONAMA n° 357/05 para águas doces Classe 2, além do processo de eutrofização das águas do corpo hídrico 1.Editora Verde2018-04-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersiontext/htmlapplication/pdfapplication/pdfapplication/pdfapplication/pdfhttps://www.gvaa.com.br/revista/index.php/RVADS/article/view/546710.18378/rvads.v13i2.5467Revista Verde de Agroecologia e Desenvolvimento Sustentável; Vol. 13 No. 2 (2018); 235 - 240Revista Verde de Agroecologia e Desenvolvimento Sustentável; Vol. 13 Núm. 2 (2018); 235 - 240Revista Verde de Agroecologia e Desenvolvimento Sustentável; v. 13 n. 2 (2018); 235 - 2401981-8203reponame:Revista Verde de Agroecologia e Desenvolvimento Sustentavelinstname:Grupo Verde de Agroecologia e Abelhas (GVAA)instacron:GVAAporhttps://www.gvaa.com.br/revista/index.php/RVADS/article/view/5467/5858https://www.gvaa.com.br/revista/index.php/RVADS/article/view/5467/5859https://www.gvaa.com.br/revista/index.php/RVADS/article/view/5467/9436https://www.gvaa.com.br/revista/index.php/RVADS/article/view/5467/9437https://www.gvaa.com.br/revista/index.php/RVADS/article/view/5467/9438Copyright (c) 2018 Maria Iraildes de Almeida Silva Matias et al.info:eu-repo/semantics/openAccessMatias, Maria Iraildes de Almeida SilvaSantos, João Victor da SilvaFreitas, Rômulo Magno OliveiraMatias, Larissa Carolina Silva2021-06-14T13:14:14Zoai:ojs.gvaa.com.br:article/5467Revistahttps://www.gvaa.com.br/revista/index.php/RVADS/PUBhttps://www.gvaa.com.br/revista/index.php/RVADS/oairvadsgvaa@gmail.com || patriciomaracaja@gmail.com || revistaverde1@gmail.com || suporte@antsoft.com.br1981-82031981-8203opendoar:2024-03-06T12:59:24.929357Revista Verde de Agroecologia e Desenvolvimento Sustentavel - Grupo Verde de Agroecologia e Abelhas (GVAA)false |
