Degradation Kinetics of Dehydroabietic Acid Initiated by OH Radical

摘要

Dehydroabietic acid (DHAA) is a main component of particles emitted through biomass burning. It is the major marker compound emitted from conifer fuel combustion (Fine et al., 2002; Simoneit, 2002), which can be used to distinguish softwood from hardwood combustion in source apportionment (Bergauff et al., 2009; Mochida et al., 2010). In this work, the heterogeneous degradation behavior of particulate dehydroabietic acid exposed to OH radicals have been measured under different environmental conditions using a flow reactor.
