Biomass burning, such as forest fires, domestic heating, and combustion of
agricultural residues, can have a significant impact on air quality. Representative biomass
burning tracers include levoglucosan, mannosan, and galactosan.
In this study, the concentrations of these tracers were measured at two air
monitoring stations in Seoul.
In 2018, the concentration of levoglucosan ranged from 18.6 to 211.5 ng/m3 at
Jong-ro and 17.7 to 216.4 ng/m3 at Gwang-jin, showing a pattern typically high in
winter and low in summer. The correlations of levoglucosan with PM2.5, OC, EC were
high in winter and fall, while low correlations were found in spring and summer. The
effect of biomass burning on PM2.5 concentration changes in winter was large.
The concentration of levoglucosan showed different trends, relative to PM2.5 high
concentration, in March and November. In March, the concentration of levoglucosan
increased the day before the PM2.5 concentration increased rapidly. In November,
