[CEST2019_00184] Biomass burning tracers in urban and rural particles in Silesia - Poland
by Czaplicka M., Janoszka K.
Session: 50, Room:
The major tracers are thermal degradation products from the biopolymer cellulose, namely the didehydromonosaccharide derivatives levoglucosan (LG), galactosan (GA) and mannosan (MN) and the resin acid derivative dehydroabietic acid, with minor β-sitosterol. The relative proportions of levoglucosan to mannosan (LG/MN) have been used for source reconstruction of combustion derived byproducts in atmospheric aerosols. Major tracers eg. levoglucosan, galactosan and mannosan were measured at two sites in Silesia region and health resort (Krynica) during winter season 2017/2018.
