Resumo: | In this study, it was made the determination of nutrients (in the forms of orthophosphate, total phosphorus, nitrogen series, total nitrogen and total dissolved carbon) and physicochemical variables in surface waters and sediment of the Monjolinho River, in São Carlos – SP, Brazil. Six sampling points were selected (stream head waters, at the UFSCar, upstream to the effluent treatment plant, Água Quente Stream, downstream to the effluent treatment plant and near the river mouth), in which were possible to observe a tendency of increase of the impact suffered by the aquatic body along its course. These tendencies were more pronounced from the region of the upstream to the effluent treatment plant (where the urban superficial flow carries the wastes to the river) to the region downstream to the effluent treatment plant. At the Água Quente Stream and downstream to the effluent treatment plant points, the input of non-treated and treated wastewaters are responsible for the substantial increase in the concentration of nutrients and alterations in physicochemical variables that reflects the impact suffered by the river. It was also noticed a seasonal tendency of variation in the measured values in agreement to the pluviometric indices of the studied region. Evaluating the Redfield ratio values, it is postulated that the phosphorus is the limiting nutrient in this ecosystem. The Tukey tests, HCA and PCA applied to the results allowed to separate sampling points into different groups according to the data obtained for each chemical analysis, showing that there is a tendency of increase on the impact suffered by the water body from its head waters to the sampling point downstream of the effluent treatment plant. |

Foram selecionados seis pontos de amostragens (região da nascente, campus da UFSCar, montante da ETE, Córrego da Água Quente, jusante da ETE e região da foz), nos quais foi possível observar uma tendência de aumento no impacto sofrido pelo corpo hídrico no decorrer de seu percurso. Tais tendências foram mais pronunciadas a partir da região a montante da ETE (onde o escoamento superficial urbano carrega os efluentes para o corpo aquático) em direção à jusante da ETE. Nos pontos a jusante da ETE e no Córrego da Água Quente, o aporte de esgotos sanitários tratados e não-tratados são responsáveis por um acréscimo substancial na concentração de nutrientes e alterações nos variáveis físico-químicas medidas que refletem o impacto sofrido pelo rio. Observou-se uma tendência de variação sazonal nos valores obtidos, de acordo com o regime pluviométrico da região. Avaliando os valores de razão de Redfield pode-se notar que o fósforo é o nutriente limitante. Os testes de Tukey, HCA e PCA permitiram agrupar os pontos de amostragem de acordo com os dados obtidos em cada análise, mostrando que há uma tendência de aumento no impacto do Rio do Monjolinho no sentido nascente-jusante da ETE.Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq)porUniversidade Federal de São CarlosCâmpus São CarlosPrograma de Pós-Graduação em Química - PPGQUFSCarQuímica ambientalFósforoNitrogênioEutrofizaçãoÁguas superficiaisSedimentosPhosphorusNitrogenEutrophicationSurface watersSedimentCIENCIAS EXATAS E DA TERRA::QUIMICA::QUIMICA ANALITICA::ANALISE DE TRACOS E QUIMICA AMBIENTALEstudo de longa duração da distribuição espaço-temporal de nutrientes no rio do Monjolinho, São Carlos - São PauloLong-term study of the spatio-temporal distribution of nutrients in the Monjolinho river, São Carlos – São Pauloinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisOnline60060090b5c73d-8bcb-4ab1-a8ee-774897695e1einfo:eu-repo/semantics/openAccessreponame:Repositório Institucional da UFSCARinstname:Universidade Federal de São Carlos (UFSCAR)instacron:UFSCARORIGINALDissPIIB.pdfDissPIIB.pdfapplication/pdf5172977https://repositorio.ufscar.br/bitstream/ufscar/7512/1/DissPIIB.pdf795336a85e6147388b34131bae8e1a7dMD51LICENSElicense.txtlicense.txttext/plain; charset=utf-81957https://repositorio.ufscar.br/bitstream/ufscar/7512/2/license.txtae0398b6f8b235e40ad82cba6c50031dMD52TEXTDissPIIB.pdf.txtDissPIIB.pdf.txtExtracted texttext/plain178894https://repositorio.ufscar.br/bitstream/ufscar/7512/3/DissPIIB.pdf.txt0fe30b6a64c323ab99dd544fb82b801cMD53THUMBNAILDissPIIB.pdf.jpgDissPIIB.pdf.jpgIM Thumbnailimage/jpeg9812https://repositorio.ufscar.br/bitstream/ufscar/7512/4/DissPIIB.pdf.jpg78e673c1cf4f26ca5dcddb36772871fcMD54ufscar/75122023-09-18 18:30:52.522oai:repositorio.ufscar.br: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Repositório InstitucionalPUBhttps://repositorio.ufscar.br/oai/requestopendoar:43222023-09-18T18:30:52Repositório Institucional da UFSCAR - Universidade Federal de São Carlos (UFSCAR)false |

description |
In this study, it was made the determination of nutrients (in the forms of orthophosphate, total phosphorus, nitrogen series, total nitrogen and total dissolved carbon) and physicochemical variables in surface waters and sediment of the Monjolinho River, in São Carlos – SP, Brazil. Six sampling points were selected (stream head waters, at the UFSCar, upstream to the effluent treatment plant, Água Quente Stream, downstream to the effluent treatment plant and near the river mouth), in which were possible to observe a tendency of increase of the impact suffered by the aquatic body along its course. These tendencies were more pronounced from the region of the upstream to the effluent treatment plant (where the urban superficial flow carries the wastes to the river) to the region downstream to the effluent treatment plant. At the Água Quente Stream and downstream to the effluent treatment plant points, the input of non-treated and treated wastewaters are responsible for the substantial increase in the concentration of nutrients and alterations in physicochemical variables that reflects the impact suffered by the river. It was also noticed a seasonal tendency of variation in the measured values in agreement to the pluviometric indices of the studied region. Evaluating the Redfield ratio values, it is postulated that the phosphorus is the limiting nutrient in this ecosystem. The Tukey tests, HCA and PCA applied to the results allowed to separate sampling points into different groups according to the data obtained for each chemical analysis, showing that there is a tendency of increase on the impact suffered by the water body from its head waters to the sampling point downstream of the effluent treatment plant. |
