Overview

Analysis of filter samples from a series of chamber experiments combining biomass burning emissions with dust particles. Biogenic and anthropogenic volatile organic compounds (VOCs) are emitted to the atmosphere and get oxidized through gas-phase chemical reactions to secondary organic aerosol (SOA) precursor compounds that can condense on surfaces. The application of atmospheric simulation chambers allows for the investigation of aerosol processing over a longer period of time. In a combined study, the interaction between added dust and biomass burning aerosols were investigated in early 2026. Specific biomass burning aerosols were introduced in the chamber alongside varying amounts of dust aerosols. Furthermore, the resulting mixed aerosol was subjected to photochemical oxidation, leading to formation of SOA. As a preliminary result, the formation of SOA was found to be smaller with increased addition of dust.
