Resumo: | Air is a vital natural environmental component for the existence of human beings and other living organisms. The objective of this study was to spatially determine the concentration levels of the particulate matter generated by the coal mining activity in Moatize. To find out how much of the total suspended particles (TSP) matter was available, dust samples were collected from 5 different residential locations around the coal mining areas. The study covered two seasons of the year, the dry and the rainy of 2015, thus making it possible to observe the seasonality in the study area. The TSP matters were sampled through a PVC membrane (filter) by inert impaction and analyzed using a gravimetric technique. The results obtained indicated that the average annual concentrations of TSP were higher for 25 de Setembro, 154.24 µg/m3 in comparison to the remaining residential locations, such as Minas Moatize, Liberdade, Carbomoc and Comunidade Cateme, 126,66 µg/m3, 132,40 µg/m3, 133,91 µg/m3 and 4,93 µg/m3, respectively. The average concentration value for the dry period was higher compared to the rainy period. In general, the intensity of pollution caused by dust concentration is significant in sites close to the coal mining area and located in the preferential range of southeastern winds. |

El objetivo del trabajo fue determinar espacialmente los niveles de concentración del material particulado generado por la actividad minera del carbón en Moatize. Para averiguar la cantidad total de partículas suspendidas (PTS), se recolectaron muestras de polvo de 5 diferentes locales residenciales alrededor de las áreas mineras de carbón. El estudio abarcó dos estaciones del año, la seca y la lluviosa 2015, lo que permitió observar la estacionalidad en el lugar de estudio. Los PTS se muestrearon a través de una membrana de PVC (filtro) mediante impactación inerte y se analizaron mediante la técnica gravimétrica. Los resultados obtenidos indicaron que las concentraciones medias anuales de PTS fueron superiores para el 25 de septiembre, 154,24 µg/m3 en comparación con los barrios Minas Moatize, Liberdade, Carbomoc y Comunidade Cateme, 126,66 µg/m3, 132,40 µg/m3, 133,91 µg/m3 y 4,93 µg/m3, respectivamente. El valor de concentración promedio para el período seco fue mayor en comparación con el período lluvioso. En general, la intensidad de la contaminación causada por la concentración de polvo es significativa en lugares cercanos al área minera del carbón y ubicados en el rango preferencial de los vientos del sureste.O ar é componente ambiental natural vital para a existência de seres humanos e outros organismos vivos. O objetivo do trabalho foi determinar espacialmente os níveis de concentrações do material particulado gerado pela atividade de mineração do carvão em Moatize. Para saber o quanto de partículas totais em suspensão (PTS), amostras de poeira foram coletadas a partir de 5 diferentes locais residenciais em torno das áreas de mineração do carvão. O estudo abrangeu duas estações do ano, a seca e a chuvosa de 2015 possibilitando observar a sazonalidade no local de estudo. As PTS foram amostradas através de uma membrana de PVC (filtro) por impactação inerte e analisadas por meio da técnica gravimétrica. Os resultados obtidos indicaram que as concentrações médias anuais de PTS foram maiores para 25 de setembro, 154,24 µg m-3 em comparação aos bairros Minas Moatize, Liberdade, Carbomoc e Comunidade Cateme, 126,66 µg m-3, 132,40 µg m-3, 133,91 µg m-3 e 4,93 µg m-3, respetivamente. O valor médio da concentração para o período seco foi maior em relação ao período chuvoso. No geral a intensidade da poluição por concentração de poeira é expressiva em locais próximos da área de mineração de carvão e localizadas na faixa preferencial dos ventos do sudeste.Editora da Universidade Federal da Grande Dourados2021-07-22info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://ojs.ufgd.edu.br/entre-lugar/article/view/1479710.30612/el.v12i23.14797ENTRE-LUGAR; v. 12 n. 23 (2021); 441-4662177-78292176-9559reponame:Entre-Lugar (Online)instname:Universidade Federal da Grande Dourados (UFGD)instacron:UFGDporhttps://ojs.ufgd.edu.br/entre-lugar/article/view/14797/7922Copyright (c) 2021 ENTRE-LUGARinfo:eu-repo/semantics/openAccessMafavisse, Isaias Mutombode Campos, Valquiria2021-07-22T23:13:12Zoai:ojs.pkp.sfu.ca:article/14797Revistahttps://ojs.ufgd.edu.br/index.php/entre-lugarPUBhttps://ojs.ufgd.edu.br/index.php/entre-lugar/oaimarcosmondardo@yahoo.com.br||charleisilva@ufgd.edu.br||editora.suporte@ufgd.edu.br10.306122177-78292176-9559opendoar:2021-07-22T23:13:12Entre-Lugar (Online) - Universidade Federal da Grande Dourados (UFGD)false |
