Impacts of the air quality monitoring lack in the Brazilian great cities

Air pollutants from anthropogenic actions are emitted from various sources, for example, agriculture, industrial activities and the means of transport. In addition, some polluting agents are accidentally released, but a large number are emitted through industrial practices or other activities, which may cause diverging effects on human health and the environment. Thus, this study seeks to compile information that will help in the elaboration of measures that seek to reduce/minimize possible risks to the health of the population and the environment associated with air pollution. As well as demonstrating the impacts on the health of the population, the effects generated on the environment and the benefit of preserving green areas to maintain air quality. According to the World Health Organization (WHO), an estimated 1.3 million annual deaths worldwide are linked to exposure to air pollution. Surveys conducted in urban children in São Paulo state that NO2 levels present in atmospheric air cause typical symptoms related to respiratory problems. The environmental impact can be classified as positive or negative, in addition, for more accuracy, CONAMA Resolution no. 001/86, defines as any biological, chemical and physical change in the environment, caused directly or indirectly by anthropic actions. The deforestation of green areas for urban construction leaves the atmospheric environment susceptible to polluting gases, especially CO2, which is released by automobiles present in urban daily life; besides the direct production by the anthropic action of this gas, through destructive or leisure burns. This article highlights the importance of monitoring air quality by environmental and health experts; therefore, it is a way of assessing pollution in urban atmospheres.
