چکیده
The purpose of the present study was to estimate emissions of some pollutants (CO, NO(X), HC, SO(X), and PM) in diesel fleet due to the addition of biodiesel in different blends, as well as to assess atmospheric pollutant concentrations in the metropolitan area of Porto Alegre (MAPA). The methodology was based on inventories from mobile sources based on US EPA's technical report. Regarding air quality the following parameters were determined: PM(10), PM(2.5), CO, NO(X), O(3), SO(2), HC and PAHs. The results showed a decrease for emissions PM, CO, and HC, and a slight increase for NO(X). The characterization of atmospheric pollutants in the metropolitan area of Porto Alegre showed that they are influenced by mobile sources, particularly diesel vehicles. The diagnosis of ratios analysis that was applied to facilitate the identification of sources of PAHs, indicated an influence of diesel oil.
