“…A number of natural and anthropogenic outdoor sources are known for formaldehyde. ( 34 ) Like other VOCs, it is a biogenic compound and part of plant physiological and plant/atmosphere exchange processes. ( 35 ) In 1927, Freudenberg and Harder identified formaldehyde as a decomposition product of lignin.…”

“…Acetonitrile has commonly been used as a marker compound for emissions from biomass burning (de Gouw et al, 2003(de Gouw et al, , 2006Holzinger et al, 1999). The oxygenated VOCs (OVOCs) and aromatic VOCs (benzene and toluene) have also been linked to biomass burning in different studies (Koppmann and Wildt, 2007;de Gouw et al, 2006).…”

Abstract. In this study a long-term volatile organic compound (VOCs) concentration data set, measured at the SMEAR II (Station for Measuring Ecosystem–Atmosphere Relations) boreal forest site in Hyytiälä, Finland during the years 2006–2011, was analyzed in order to identify source areas and profiles of the observed VOCs. VOC mixing ratios were measured using proton transfer reaction mass spectrometry. Four-day HYSPLIT 4 (Hybrid Single Particle Lagrangian Integrated Trajectory) backward trajectories and the Unmix 6.0 receptor model were used for source area and source composition analysis. Two major forest fire events in Russia took place during the measurement period. The effect of these fires was clearly visible in the trajectory analysis, lending confidence to the method employed with this data set. Elevated volume mixing ratios (VMRs) of non-biogenic VOCs related to forest fires, e.g. acetonitrile and aromatic VOCs, were observed. Ten major source areas for long-lived VOCs (methanol, acetonitrile, acetaldehyde, acetone, benzene, and toluene) observed at the SMEAR II site were identified. The main source areas for all the targeted VOCs were western Russia, northern Poland, Kaliningrad, and the Baltic countries. Industrial areas in northern continental Europe were also found to be source areas for certain VOCs. Both trajectory and receptor analysis showed that air masses from northern Fennoscandia were less polluted with respect to both the VOCs studied and other trace gases (CO, SO2 and NOx), compared to areas of eastern and western continental Europe, western Russia, and southern Fennoscandia.

Abstract. In this study a long-term volatile organic compounds (VOCs) data set, measured at the SMEAR II (Station for measuring Ecosystem–Atmosphere Relations) boreal forest site at Hyytiälä, Finland during the years 2006–2011, was investigated. VOC mixing ratios were measured using proton transfer reaction mass spectrometry. Four-day backward trajectories and the Unmix 6.0 receptor model were used for source area and source composition analysis. Two major forest fire events, one in Eastern Europe and one in Russia, took place during the measurement period. The effect of these fires was clearly visible in the trajectory analysis, lending confidence to the method employed with this data set. Elevated volume mixing ratios (VMRs) of non-biogenic VOCs, e.g. acetonitrile and aromatic VOCs, related to forest fires were observed. Ten major source areas for long-lived VOCs (methanol, acetonitrile, acetaldehyde, acetone, benzene and toluene) were identified at the SMEAR II site.
