Resumo: | The Brazilian capitals have been presenting environmental problems of diverse orders, reverberating negatively in the life quality of its inhabitants. São Luís, the State of Maranhão's capital, with a population of larger than 1 million citizens consists of a good example of a Brazilian capital that can coexist with environmental atmospheric problems. The research when analyzing the atmospheric pollution in the city further sought to correlate with its geographic aspects (physical and human) by comprehending that it's only possible to discern the complexity of the problem when it's not limited only to the pollution sources and the emitted volumes. The collected data were obtained from seven automatic stations of air quality belonging to Company Vale S/A and oriented by an evolutive and integrated analysis. The achieved results by the study indicated that the EMAP station, localized in the county's port zone, was the sole one that presented values that exceeded the established limits by the Law with the subsequent values in percentages for Unbreathable Particles in the following years: in 2013 (68%); 2014 (87%); 20 15 (110%) and 2016 (2%). It was also possible to distinguish between the months from July to December, in the dry season, significant rises in the atmospheric pollution indexes in the order of 24,5% for Unbreathable Particles and 35% for Total Particles in Suspension. It is concluded beyond polluting sources, that in São Luís case, the rainfall and wind are climatic atributes significant in the determination the levels of pollution in the study area. |

São Luís, capital do estado do Maranhão, com uma população de mais de 1 milhão de habitantes constitui um bom exemplo de capital brasileira que também convive com problemas ambientais atmosféricos. A pesquisa ao analisar a poluição atmosférica da cidade de São Luís procurou também correlacionar com seus aspectos geográficos (físicos e humanos) por entender que somente é possível compreender a complexidade do problema não se limitando apenas às suas fontes poluidoras e volumes emitidos. Os dados coletados foram obtidos de sete estações automáticas de monitoramento de qualidade do ar pertencentes à Companhia Vale S/A dentro do município de São Luís e orientados para uma análise evolutiva e integrada. Os resultados alcançados pela pesquisa indicaram que a estação EMAP, localizada na zona portuária do município, foi a única que apresentou valores que ultrapassaram os limites estabelecidos pela Lei com os seguintes valores de porcentagens para Particulados Inaláveis nos seguintes anos: em 2013 (68%); 2014 (87%); 2015 (110%) e 2016 (2%). Também foi possível identificar que entre os meses de julho a dezembro, na estação seca, foram identificados aumentos significativos dos índices de poluição atmosférica na ordem de 25,6% para Particulados Inaláveis e 35% para Particulados Totais em Suspensão. Concluímos que além das fontes poluidoras, no caso de São Luís, a pluviosidade e o vento são fatores geográficos preponderantes na determinação dos níveis de poluição na cidade.Universidade Federal de Uberlândia2020-11-12info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfapplication/pdfhttps://seer.ufu.br/index.php/sociedadenatureza/article/view/5616210.14393/SN-v32-2020-56162Sociedade & Natureza; Vol. 32 (2020); 808-819Sociedade & Natureza; v. 32 (2020); 808-8191982-45130103-1570reponame:Sociedade & natureza (Online)instname:Universidade Federal de Uberlândia (UFU)instacron:UFUporenghttps://seer.ufu.br/index.php/sociedadenatureza/article/view/56162/30188https://seer.ufu.br/index.php/sociedadenatureza/article/view/56162/30189Copyright (c) 2020 Juarez Mota Pinheiro, Luís Antônio Bittar Venturi, Emerson Galvaniinfo:eu-repo/semantics/openAccessPinheiro, Juarez MotaBittar Venturi, Luís Antônio Galvani, Emerson2021-07-01T16:18:20Zoai:ojs.www.seer.ufu.br:article/56162Revistahttp://www.sociedadenatureza.ig.ufu.br/PUBhttps://seer.ufu.br/index.php/sociedadenatureza/oai||sociedade.natureza.ufu@gmail.com|| lucianamelo@ufu.br1982-45130103-1570opendoar:2021-07-01T16:18:20Sociedade & natureza (Online) - Universidade Federal de Uberlândia (UFU)false |
