Impact of atmospheric transformation and ageing on the toxicity of anthropogenic and biogenic aerosols
Session ID#: 79815
Session Description:
Natural and anthropogenic aerosol emissions (primary aerosols) undergo rapid transformation processes in the atmosphere. This leads to new formation of particulate mass (secondary aerosols), drastic changes in the chemical composition and the physical properties of the aerosol. The transformation processes can be photochemically induced or driven by dark-chemistry. The impact of the transformation process on ambient air quality and health effects is only poorly understood. We invite researchers working in the field of atmospheric chemistry and physics and aerosol toxicologists working on atmospheric transformation processes and their effects to contribute to this multidisciplinary GEOHEALTH session.
