PM10 and PM2.5 exposure of the population in Austria

Exposure of the public to particulate matter (PM10 and PM2.5) is the decisive basis for determining the health effects of particulate matter. It is used as an important environmental indicator at international level (e.g. for the OECD’s Better Life Index). This study documents the methodological basis for determining the exposure of the Austrian population by PM10 and PM2.5 on the basis of the concept of representative areas. Topographical data, measurement and emissions data of particulate matter and population data are related. An annual update of the exposure calculation is therefore possible. The mean PM2.5 exposure of the Austrian population, calculated as the result of this study, shows a significant decrease from 19.3 to 11.5?g/m³ between 2005 and 2016.
