Understanding the Airborne Particles with Biological Origin
We develop techniques for bioaerosol measurement and investigate the bioaerosols in Switzerland and other countries. An example is the study on size-resolved endotoxin and oxidative potential of ambient particles in Beijing and Zürich. The results demonstrated that components of airborne particles in different regions could vary greatly. Therefore, improvement of the current air quality standards which only consider the airborne particulate matter mass, can be achieved by identification of the more harmful components such as endotoxin, and implementation of control strategies with focus on the harmful components.
