According to recent research, car exhausts are responsible for only one third of traffic pollution.
The study, published in Atmospheric Environment, states that almost half of the air pollution from road traffic is due to non-exhausting sources (such as brake wear, road wear, and particles raised from the road by the passage of vehicles).
Prof. Ranjeet Sokhi, of the University of Hertfordshire, who led the study, says: “In terms of mass, non-exhaust sources can be more impactful, but legislative control has focused on exhaust emissions. As the exhaust emission regulations become more stringent, the non-exhaust sources become proportionately more important. The control of exhaust emissions only may not be sufficient to meet the legal standards for air quality “.
