Study of PM2.5 dispersion from the BR-324 and BA-093 motorways

Previous studies carried out in the Simões Filho region have shown that the population reports various inconveniences due to the presence of dust, which there are indications comes from industrial and vehicular activities and may consist mainly of particulate matter. Given this scenario, the aim of this study was to carry out dispersion studies, using the AERMOD view and CALRoads view software, to understand the dynamics of the spread of particulate matter smaller than 2.5 micrometres (MP2.5) in the atmosphere of Simões Filho (SF) - BA of vehicular origin, due to traffic on the BR-324 and BA-093 motorways in the municipality studied, and of industrial origin, due to the presence of an Fe-Mn alloy electrosiderurgical industry, in order to predict the possible environmental and community impacts caused by automotive and industrial emissions in the region studied.
