Short summary
Through an environmental chamber approach, we find that a small increase in aromatic content in gasoline fuel will result in a large enhancement in the secondary organic aerosol formation from vehicle exhaust. The higher emissions of both monocyclic and polycyclic aromatic organic compounds from the high-aromatic fuel played an essential role. Our findings highlight the importance of more stringent regulation of gasoline aromatic content for air quality in urban areas.
