Resumo: | In 2015, the Gualaxo do Norte River basin suffered from a serious environmental disaster that affected the quality of the river environment due to the disruption of the Fundão dam structures located in Bento Rodrigues Sub-district, Mariana, Minas Gerais/ Brazil. Due to the impacts of the disaster and in view of the economic and social importance of the Gualaxo do Norte river basin, this research assessed the current situation of the river basin through sediment studies with the aim of assessing the environmental impacts caused by tailings tailings. iron ore from the rupture and other sources of pollution in the bottom sediment. To this end, water and sediment samples were collected at 27 stations throughout the Gualaxo do Norte River basin in August 2016 and January 2017, upstream (unaffected by the dam breach) and downstream of the disaster. (affected by dam tailings). The sediment results indicate that in sampling stations not affected by the disaster, metal and semimetal concentrations reflect the geology of the Iron Quadrangle. However, in the area affected by the environmental disaster, there were changes in the chemical and physical properties of the bottom sediment, especially in iron concentrations. This has reflected in contamination and iron enrichment at stations downstream of the environmental disaster. |

Devido aos impactos do desastre e tendo em vista a importância econômica e social da bacia hidrográfica do Rio Gualaxo do Norte, esta pesquisa teve como objetivo avaliar a situação atual da bacia hidrográfica por meio de estudos de sedimentos com o objetivo de avaliar os impactos ambientais causados pelos rejeitos de minério de ferro, oriundos do rompimento e por outras fontes de poluição nos sedimentos de fundo. Para tanto, foram coletadas amostras de água e sedimentos em 27 estações ao longo de toda a bacia do Rio Gualaxo do Norte em agosto de 2016 e janeiro de 2017, no trecho a montante (não afetado pelo rompimento da barragem) e a jusante ao desastre ambiental (afetado pelos rejeitos da barragem). Os resultados dos sedimentos indicam que, nas estações de amostragem não afetadas pelo desastre, as concentrações dos metais e semimetais refletem a geologia do Quadrilátero Ferrífero. No entanto, na área afetada pelo desastre ambiental, houve mudanças nas propriedades químicas e físicas do sedimento de fundo, principalmente nas concentrações de ferro. Isso refletiu na contaminação e no enriquecimento por ferro nas estações a jusante ao desastre ambiental.Research, Society and Development2020-01-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/189510.33448/rsd-v9i2.1895Research, Society and Development; Vol. 9 No. 2; e01921895Research, Society and Development; Vol. 9 Núm. 2; e01921895Research, Society and Development; v. 9 n. 2; e019218952525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIporhttps://rsdjournal.org/index.php/rsd/article/view/1895/1686Copyright (c) 2019 Deyse Almeida dos Reis, Hubert Mathias Peter Roeser, Aníbal da Fonseca Santiagoinfo:eu-repo/semantics/openAccessReis, Deyse Almeida dosRoeser, Hubert Mathias PeterSantiago, Aníbal da Fonseca2020-08-20T18:08:48Zoai:ojs.pkp.sfu.ca:article/1895Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:26:45.872063Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false |
