Resumo: | Pollution of water bodies by microplastics has become a major environmental problem. In this sense, the aim of the study was to qualitatively analyze the incidence of microplastics in the aquatic ecosystem under the influence of human activities. The study was developed at Córrego do Barbado, located in Cuiabá-MT. The analysis of environmental integrity was composed of demographic density, land use and occupation, deforestation (vegetation cover) and urban solid waste management. For the analysis of microplastics in washing water, water and stream sediment, collections were performed at four sample points. The obtaining of microplastics in washing water was through the collection of three vials of 1 liter each in homes, to obtain microplastics in the stream water, 100 liters were collected in triplicate per sampling point and to obtain microplastics in the sediment. 1 kilogram of sample was collected, consisting of a sampling point. For the processing of the samples, granulometric sieves, saline solution and hydrogen peroxide were used. Microplastics were manually quantified by separating them with the aid of a needle forceps using a stereoscope. The results of environmental integrity showed that there are factors that cooperate for the environmental degradation of the stream, requiring measures for environmental education and awareness, in addition to inspection and monitoring of the stream. All the samples of the washing water had microplastics, specifically fibers, mostly green and black. For the physical and chemical parameters the results of electrical conductivity, dissolved oxygen, total solids and turbidity demonstrated the pollution of the water body. The incidence of microplastics in water was higher than the amount of microplastics in the sediment and the highest amounts of microplastics were found in May for both water and sediment. As for the type of microplastic, the majority found was fiber and the predominant color of the microplastics found was blue. In view of the above, it is concluded that the Barbado Stream, over the years, has suffered direct and indirect influence from human activities, affecting environmental integrity around the watershed, as well as altering water quality. In addition, microplastics are present in large quantities, both in water and in sediment, directly affecting the entire ecosystem. |

O estudo foi desenvolvido no Córrego do Barbado, localizado em Cuiabá-MT. A análise da integridade ambiental foi composta pela densidade demográfica, uso e ocupação do solo, desmatamento (cobertura vegetal) e gestão dos resíduos sólidos urbanos. Para a análise de microplásticos em água de lavagem de roupa, água e sedimento do córrego as coletas foram realizadas em quatro pontos amostrais. A obtenção dos microplásticos em água de lavagem de roupa foi através de coleta de três frascos de 1 litro cada nas residências, para a obtenção dos microplásticos na água do córrego foram coletados 100 litros em triplicata por ponto amostral e para a obtenção de microplásticos no sedimento foram coletados 1 quilograma de amostra composta por ponto amostral. Para o processamento das amostras foram utilizadas peneiras granulométricas, solução salina e peróxido de hidrogênio. Os microplásticos foram quantificados manualmente separando-os com auxílio de uma pinça agulha utilizando aparelho estereoscópio. Os resultados da integridade ambiental apresentaram que existem fatores que cooperam para a degradação ambiental do córrego, necessitando de medidas para a educação e conscientização ambiental, além de fiscalização e monitoramento do córrego. Todas as amostras da água da lavagem de roupa possuíam microplásticos, especificamente fibras e em sua maioria de colorações verde e preta. Para os parâmetros físicos e químicos os resultados de condutividade elétrica, oxigênio dissolvido, sólidos totais e turbidez demonstraram a poluição do corpo hídrico. A incidência de microplásticos na água foi superior a quantidade de microplásticos no sedimento e as maiores quantidades de microplásticos foram encontradas no mês de maio tanto para água quanto para sedimento. Quanto ao tipo de microplástico a maioria encontrada foi fibra e a cor predominante dos microplásticos encontrados foi azul. Diante do exposto, conclui-se que o Córrego do Barbado, tem sofrido ao longo dos anos, influência direta e indireta das atividades antrópicas, afetando a integridade ambiental no entorno da microbacia, bem como alterando a qualidade da água. Ademais os microplásticos estão presentes em grande quantidade, tanto na água quanto no sedimento, afetando diretamente todo o ecossistema.Universidade Federal de Mato GrossoBrasilFaculdade de Arquitetura, Engenharia e Tecnologia (FAET)UFMT CUC - CuiabáPrograma de Pós-Graduação em Recursos HídricosCaixeta, Danila SoaresPrado, Rogério Junqueirahttp://lattes.cnpq.br/8485801877869591http://lattes.cnpq.br/8314296350945580Caixeta, Danila Soares049.556.026-06http://lattes.cnpq.br/8314296350945580Girard, Pierre257.926.348-90http://lattes.cnpq.br/0442161398765567049.556.026-06643.480.401-68Silva, Julia Ferreira da693.568.406-44http://lattes.cnpq.br/2063303423527424Carmo Junior, Gersina Nobre da Rocha486.674.801-00http://lattes.cnpq.br/8920941888298909Chalegra, Stéfany Marchi de Andrade2023-07-26T16:51:20Z2021-04-152023-07-26T16:51:20Z2020-03-30info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisCHALEGRA, Stéfany Marchi de Andrade.
