Emissions from wildland fires and biomass fuel use contribute to regional air pollution events, global scale radiative forcing and climate change, and cause severe health effects. However, the role of organic compounds in these processes is still largely unknown and underestimated.
For this reason, the OAL team performs combustion experiments in the DRI’s combustion chamber to characterize in details chemical and physical properties of biomass-burning emissions, especially organic compounds.
Moreover, to study atmospheric aging of combustion pollutants, OAL students operate the oxidation the flow reactor (OFR) that needs only 1-2 minutes to mimic 7 days of oxidation in real atmospheric conditions.
