摘要: Abstract This work aims to assess the impacts of biodiesel blends use in road-traffic on air quality. In this frame, quality numerical modelling system WRF-EURAD was applied over Portugal and Porto urban area, forced by two emission scenarios (including CO, NOx, PM10, PM2.5, NMVOC, formaldehyde, acetaldehyde, acrolein benzene): a reference scenario, without biofuels, scenario where B20 fuel (20% biodiesel/80% diesel, v/v) is used diesel vehicle fleet. Regarding carbonyl compounds, pointed out that can promote an increase 20% acetaldehyde emissions, leading increments equivalent ozone production. On other hand, through exercise, it verified helps controlling pollution, improving CO NO 2 concentrations airshed about 10%, respectively, taking into account regional simulation grid. However, according scale simulation, levels 1%, due B20, area. For remaining studied pollutants, namely PM10 mean will be reduced all territory, however negligible amount
