Caracterização dos áerossis urbanos na cidade de Maputo

Abstract

The control of substances emitted into the environment from different processes that occur in nature, both natural and anthropic, has been deserving greater emphasis on a global scale, as the studies that have been carried out reveal that Man, despite needing of the environment for its survival, it is the main enemy of the same. The activities he carries out significantly contribute to the degradation of the environment and the consequent degradation of living conditions. It is in this context that the present work was carried out, with the aim of trying to quantify what is emitted in the urban atmosphere of Maputo, with regard to microscopic particles (Aerosols). For the present work, two small volume samplers were used to collect atmospheric aerosol samples. After collecting the samples, they were analyzed. The analysis consisted of determining the mass and concentration of aerosols in the samples, and it was concluded that, compared to large urban centers, the city of Maputo has low levels of air pollution, despite the fact that there are some points in the city. where, on certain days, the values ​​exceed international air quality standards; such are the cases of the dumpster area of ​​Hulene and the University Campus.(TRADUÇÃO NOSSA)
