Short summary
Road traffic is an important source of air pollution. This study investigates the relationship between traffic-related airborne carbonaceous particles and the composition of traffic to reveal how emissions from different vehicle types affect ambient air quality. On average, LPG vehicles showed very small contributions, while gasoline- and diesel-powered vehicles emitted similar total amounts of carbon-containing particles but with differences in chemical composition.
