Aerosol and Health

The vision of the Aerosols and Health Group is to better understand the effect of air pollution on people's health and what role anthropogenic and natural emissions play now and in the future. While there are clear links between aerosol exposure and increased mortality and morbidity risk, little is known about how the properties of aerosols affect their toxicity and which emission sources are most important for human health.

Our mission is to quantify the aerosol sources and identify those most harmful to human health. To that end, we analyze aerosol archives with mass spectrometry and data mining techniques to identify aerosol sources around the world. Furthermore, we are interested in determining the role of particle sources, and thus their chemical and physical properties, in the harmfulness of particles to human health, both through emerging chemical metrics and on a population level. Moreover, we simulate air quality using our in-house model to describe the types of aerosols to which the population is exposed today and in a future shaped by emission reductions.
