  • Urban air quality : The challenge of traffic non-exhaust emissions

    • About 400,000 premature adult deaths attributable to air pollution occur each year in the European Region. Road transport emissions account for a significant share of this burden. While important technological improvements have been made for reducing particulate matter (PM) emissions from motor exhausts, no actions are currently in place to reduce the non-exhaust part of emissions such as those from brake wear, road wear, tyre wear and road dust resuspension. These "non-exhaust" sources contribute easily as much and often more than the tailpipe exhaust to the ambient air PM concentrations in cities, and their relative contribution to ambient PM is destined to increase in the future, posing obvious research and policy challenges.This review highlights the major and more recent research findings in four complementary fields of research and seeks to identify the current gaps in research and policy with regard to non-exhaust emissions. The objective of this article is to encourage and direct future research towards an improved understanding on the relationship between emissions, concentrations, exposure and health impact and on the effectiveness of potential remediation measures in the urban environment.

  • A Review of Road Traffic-Derived Non-Exhaust Particles : Emissions, Physicochemical Characteristics, Health Risks, and Mitigation Measures
  • 2022
  • Ingår i: Environmental Science and Technology. - : AMER CHEMICAL SOC. - 0013-936X .- 1520-5851. ; 56:11, s. 6813-6835
  • Forskningsöversikt (refereegranskat)abstract
    • Implementation of regulatory standards has reduced exhaust emissionsof particulate matter from road traffic substantially in the developed world. However,nonexhaust particle emissions arising from the wear of brakes, tires, and the roadsurface, together with the resuspension of road dust, are unregulated and exceedexhaust emissions in many jurisdictions. While knowledge of the sources ofnonexhaust particles is fairly good, source-specific measurements of airborneconcentrations are few, and studies of the toxicology and epidemiology do not givea clear picture of the health risk posed. This paper reviews the current state ofknowledge, with a strong focus on health-related research, highlighting areas wherefurther research is an essential prerequisite for developing focused policy responses tononexhaust particles.
