Comprehensive characterization of wintertime submicron aerosol in a Nordic town influenced by residential wood combustion, traffic and industrial sources
Anthropogenic particulate matter with sizes smaller than 1 μm (PM1) is a concerning air pollutant that can affect human health. In this study, we present PM1 measurements performed in a small town in northern Finland that is exposed to contrasting sources (residential wood burning, traffic, industri...

Anthropogenic particulate matter with sizes smaller than 1 μm (PM1) is a concerning air pollutant that can affect human health. In this study, we present PM1 measurements performed in a small town in northern Finland that is exposed to contrasting sources (residential wood burning, traffic, industrial activities). The study was conducted in winter 2021, with a mobile laboratory equipped with sophisticated on-line aerosol instrumentation. The results showed a significant increase in particulate mass and number concentrations from biomass burning in residential areas and town centre due to the high share of residences using biomass burning. Organics and equivalent black carbon (eBC) clearly dominated the PM1 composition during the highest pollution levels, followed by inorganics (sulfate, nitrate and ammonium). PAHs and a few elements (e.g. K, Cl, Zn) were as well higher during evening. A source apportionment confirmed the association between high PM1 values and biomass burning, even though the traffic contribution was also important. PM1 measurements at an industrial area showed an increase in sulfate, organics, eBC, and a few elements (e.g. Cl, Na, Fe), and characteristic size distributions.
