Resumo: | The objective of this study was to evaluate the influence of the release of effluent treated by maturation pond (ETE Malvas) on phytoplankton in a partially urbanized 1,100m stretch of the Salgadinho river (Juazeiro do Norte, Ceará, Brazil) and its relationship with limnological characteristics. Four points are selected: (P1) upstream of the outfall ETE Malvas, (P2) in the outfall, (P3) 50 downstream of the outfall and (P4) 1100 downstream of the outfall. The collections were performed during the dry season corresponding to the months of June, July and August 2017, having as physicochemical variables: pH, water temperature, turbidity, total alkalinity, chlorophyll a, COD, OD and nitrogen fractions; and for qualitative evaluation of phytoplankton: relative density, occurrence index and concentration of organisms. The effluent released by the ETE outfall influences the 1100m section of the river in an unfavorable way, as it promotes an environment with low phytoplankton diversity in the downstream points, due to the numerous contribution of the species Planktothrix isothrix (Cyanobacteria division), when compared with the conditions of the upstream section (P1) of the emissary, which hinted at a state of pollution, due to the more significant presence of total ammonia. Furthermore, the effluent still positively interferes with limnological aspects by immediately raising dissolved oxygen downstream and, negatively with the decomposition of algal biomass, either by increasing turbidity and converting abundant algal organic nitrogen into total ammonia. |

Las recolecciones se realizaron durante la estación seca correspondiente a los meses de junio, julio y agosto de 2017, con variables físicas y químicas: pH, temperatura del agua, turbidez, alcalinidad total, clorofila a, DQO, OD y fracciones nitrogenadas; y para la evaluación cualitativa del fitoplancton: densidad relativa, índice de ocurrencia y concentración de organismos. El efluente liberado por el emisario ETE tiene una influencia desfavorable en el tramo de 1100m del río, ya que promueve un ambiente con baja diversidad de fitoplancton en los puntos aguas abajo, debido a la gran contribución de la especie Planktothrix isothrix (división de Cyanobacteria), en comparación con Las condiciones de la sección aguas arriba (P1) del emisario, que insinuó un estado de contaminación, debido a la presencia más significativa de amoníaco total. Además, el efluente todavía interfiere positivamente con los aspectos limnológicos al elevar inmediatamente el oxígeno disuelto aguas abajo y, negativamente con la descomposición de la biomasa de algas, al aumentar la turbidez y convertir el nitrógeno orgánico de algas abundante en amoníaco total.O estudo objetivou avaliar a influência do lançamento do efluente tratado por lagoa de maturação (ETE Malvas) sobre o fitoplâncton em uma seção parcialmente urbanizado do rio Salgadinho (Juazeiro do Norte, Ceará) e sua relação com as características limnológicas, sendo para tal selecionados quatro pontos: (P1) a montante do emissário ETE Malvas, (P2) no emissário, (P3) 50m a jusante do emissário e (P4) 1100m a jusante do emissário. As coletas foram realizadas em época de estiagem correspondente aos meses de junho, julho e agosto de 2017, tendo como variáveis físico-químicas: pH, temperatura da água, turbidez, alcalinidade total, clorofila a, DQO, OD e frações nitrogenadas; e para avaliação qualitativa de fitoplâncton: densidade relativa, índice de ocorrência e concentração de organismos. O efluente lançado pelo emissário da ETE influencia de forma desfavorável no trecho de 1100m do rio, por promover um ambiente com baixa diversidade fitoplanctônica nos pontos a jusante, em função da contribuição numerosa da espécie Planktothrix isothrix (divisão Cyanobacteria), quando se compara com as condições do trecho a montante (P1) do emissário, que insinuou um estado de poluição, pela presença mais expressiva de amônia total. Ademais, o efluente ainda interfere nos aspectos limnológicos de forma positiva ao elevar imediatamente o oxigênio dissolvido a jusante e, negativamente com a decomposição da biomassa algal, seja pela elevação da turbidez e conversão do abundante nitrogênio orgânico algal em amônia total.Editora Verde2020-01-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersiontext/htmlapplication/pdfhttps://www.gvaa.com.br/revista/index.php/RVADS/article/view/694210.18378/rvads.v15i1.6942Revista Verde de Agroecologia e Desenvolvimento Sustentável; Vol. 15 No. 1 (2020); 83 - 92Revista Verde de Agroecologia e Desenvolvimento Sustentável; Vol. 15 Núm. 1 (2020); 83 - 92Revista Verde de Agroecologia e Desenvolvimento Sustentável; v. 15 n. 1 (2020); 83 - 921981-8203reponame: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/6942/7191https://www.gvaa.com.br/revista/index.php/RVADS/article/view/6942/7278Copyright (c) 2020 Marise Daniele Maciel Lima et al.info:eu-repo/semantics/openAccessLima, Marise Daniele MacielSantos, Maria Aparecida PereiraRangel Junior, AdjutoSantos, Yannice Tatiane da Costa2021-06-14T13:12:51Zoai:ojs.gvaa.com.br:article/6942Revistahttps://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:2024-03-06T12:59:37.507505Revista Verde de Agroecologia e Desenvolvimento Sustentavel - Grupo Verde de Agroecologia e Abelhas (GVAA)false |
