<abstract>
<p>Biomass burning, such as domestic heating, agricultural, and wild open-land
fires, has a significant influence on the atmosphere at the global and,
especially, at the local scale. Levoglucosan has been shown to be a good
tracer for biomass burning emissions in atmospheric particulate matter, and
several analytical techniques have been presented for the determination of
levoglucosan from filter samples. In this paper, a novel combination of a
particle-into-liquid sampler (PILS) to a high-performance anion-exchange
chromatograph (HPAEC) with the detection by a mass spectrometer (MS) is
presented for the online analysis of levoglucosan in ambient particles. The
PILS–HPAEC–MS technique enables a fast online analysis of levoglucosan
from the particulate samples. The method was tested at an urban background
station in Helsinki, Finland, in winter 2011. A comparison with simultaneous
levoglucosan measurements from filter samples by the HPAEC–MS was performed
and it showed a good agreement between the online and offline methods.
Additionally, the online levoglucosan data were compared with the biomass
burning tracer fragments measured by a high-resolution time-of-flight
aerosol mass spectrometer (HR-ToF-AMS). As there were no local biomass
burning sources close to the measurement station, online levoglucosan
measurements revealed that most of the particles from biomass burning were
either regionally distributed or long-range transported in the urban
background of Helsinki. The average levoglucosan concentrations were
relatively low (average 0.083 μg m&lt;sup&gt;&amp;minus;3&lt;/sup&gt;) during the measurement
campaign. The highest concentration peak measured for levoglucosan (1.4 μg m&lt;sup&gt;&amp;minus;3&lt;/sup&gt;)
seemed to originate from biomass burning in the Baltic countries, likely in Estonia, that was transported to Helsinki.</p>
