摘要: The purpose of the present study was to estimate emissions some pollutants (CO, NOX, HC, SOX, and PM) in diesel fleet due addition biodiesel different blends, as well assess atmospheric pollutant concentrations metropolitan area Porto Alegre (MAPA). methodology based on inventories from mobile sources US EPA’s technical report. Regarding air quality following parameters were determined: PM10, PM2.5, CO, O3, SO2, HC PAHs. results showed a decrease for PM, slight increase NOX. characterization that they are influenced by sources, particularly vehicles. diagnosis ratios analysis applied facilitate identification PAHs, indicated an influence oil.
