Short summary
Our results highlight the contribution of gasoline-direct-injection (GDI) vehicles to aerosols, both primary and secondary. The major particles from GDI vehicles are organic and soot particles; they actively participate in chemical conversions in the atmosphere, leading to morphology and composition changes in hours. Rapid ageing could be attributable to the acid-catalysed mechanism and high concentrations of gaseous pollutants. These results would be beneficial for control of PM2.5 pollution.
