Resumo: The Fundão dam failure on 5 November 2015 launched into the environment thirty-five million m³ of iron ore tailings, affecting the quality, turbidity, physicochemical parameters and the concentration of metals in the water due to the volume of suspended solids. Considering the importance of water quality for survival and for human and animal health, this article makes use of time series of concentration of toxic metals in the Doce River, covering pre and post disaster. Despite the identification of periods of greater and lesser toxicity due to the temporal distancing of the disaster occurrence, our results show a fast return to pre-disaster levels for the parameters, which were already above the legal threshold. Because of the need to ensure a safe water source for animal and human consumption, concentration of toxic metals should continue to be the focus of attention in the conventional water treatment process.

Considerando a importância do cuidado à saúde, este artigo utiliza séries temporais sobre concentrações de metais tóxicos nas águas do Rio Doce nos períodos anterior e posterior ao acidente, identificando as concentrações de metais em função do distanciamento temporal da ocorrência do desastre. Embora tenham sido identificados períodos de maior e menor toxicidade, os resultados apontam para um rápido retorno aos parâmetros de metais dissolvidos na água anteriores ao desastre, os quais já se encontravam acima dos limites legais estabelecidos. Devido aos possíveis agravos à saúde e à necessidade de se garantir a dessedentação sem risco, o monitoramento das concentrações destes metais deve continuar objeto de atenção no processo convencional de tratamento de água.UFVJM2018-06-07info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionArtigo avaliado pelos Paresapplication/pdfhttps://revistas.ufvjm.edu.br/revista-espinhaco/article/view/11310.5281/zenodo.3952940Revista Espinhaço ; Revista Espinhaço #122317-0611reponame:Revista Espinhaçoinstname:Universidade Federal dos Vales do Jequitinhonha e Mucuri (UFVJM)instacron:UFVJMporhttps://revistas.ufvjm.edu.br/revista-espinhaco/article/view/113/124Copyright (c) 2022 Revista Espinhaço https://creativecommons.org/licenses/by-nc-nd/4.0info:eu-repo/semantics/openAccessDias, Carlos AlbertoCosta, Alexandre Silvio Vieira daGuedes, Gilvan RamalhoUmbelino, Glauco Jose de MatosSousa, Leonardo Gomes deAlves, Janete HiginoSilva, Thamires Gabriele Macedo2022-07-22T18:46:54Zoai:ojs.pkp.sfu.ca:article/113Revistahttps://revistaespinhaco.com/index.php/revista/indexPUBhttps://revistas.ufvjm.edu.br/revista-espinhaco/oairevista.espinhaco@gmail.com || doug.sathler@gmail.com2317-06112317-0611opendoar:2022-07-22T18:46:54Revista Espinhaço - Universidade Federal dos Vales do Jequitinhonha e Mucuri (UFVJM)false
