The evidence that air pollution is a global threat to human health and climate is convincing, yet >400000 Europeans still die prematurely each year because of air pollution. Effective policies to reduce population exposure must efficiently target specific emission sources, as opposed to bulk particle mass (PM2.5). Recent research quantified the relative risk functions for specific aerosol types such as black carbon (BC), aerosol sources, and ultrafine particles (UFPs), which were until now only available for bulk PM. This sets the necessary framework to move beyond the state of the art and quantify the source-specific health burden of particulate air pollutants at European-scale.
CLEANAIR will analyse time series of PM concentrations from urban and regional monitoring stations across Europe. Source contributions to particle mass will be reviewed to obtain the most robust and comparable dataset. Concentration-response risk coefficients will be derived from the literature and ongoing projects. Finally, data will be integrated to quantify the public health burden of source-related metrics (PM and aerosol source contributions) for different adverse health outcomes and exposure scenarios. This research will shed light on the health burden of specific aerosol sources across Europe, on health-related aerosol research, and have a major impact on air quality improvement by targeting the most relevant sources. This novel approach will provide tools to improve air quality and reduce its health burden across Europe in an accessible manner to stakeholders and the public.
