“…For the first wood-stove burns of each day ("cold start") combustion was less vigorous and resulted in an aerosol of different composition to normal, consistent with previous studies (Miljevic et al 2010;Lamberg et al 2011). For the second and subsequent burns, the particle composition observed by the AMS was similar, as discussed below.…”

“…This is likely related to the top-down combustion of that burn (Section 2) and suggests that separate wood-stove emission factors should be considered when modeling single burns (e.g., recreational burning [Fine et al 2001]) or longterm combustion (e.g., home heating). The emission factors in Figure 3a are much higher than those in Figure 3b-d, indicating that most of the wood-stove PM consisted of refractory BC and ash (Lamberg et al 2011;Heringa et al 2012;Torvela et al 2014) rather than OM. Refractory PM emission factors were relatively constant across the starting and flaming phases.…”

Logwood and pellet stoves are popular heating sources around the world. The particulate matter emitted from such stoves contains organic particulate matter (OM), soot, and ash, each of which may have significant effects on climate and health. In this study, the primary OM (POM) emitted from a wood stove and a pellet stove operated according to standard Swiss testing protocols were characterized using aerosol mass spectrometry. The POM mass spectra were found to be highly reproducible, and contained CO C as the dominant ion. Because the POM emitted by such stoves is typically enhanced by the condensation of gaseous organics following atmospheric aging, the secondary OM (SOM) formation potential of these stoves was simulated using the Micro Smog Chamber (MSC) designed by Keller and Burtscher in 2012. In general, OM emission factors from MSCaged aerosols were comparable to lower-time-resolution results from the literature, although the MSC exposed aerosols to much higher concentrations of oxidants and therefore produced OM that was more oxidized than expected for atmospheric samples. In addition, the logwood-stove particles remained highly aspherical even after oxidation, indicating that mixing with an external aerosol is required for these particles to become spherical. The one exception to this observation occurred when the wood failed to ignite and appeared to generate tar-ball OM particles.

“…It is known that biomass burning emitted PM are of very low aerodynamic diameter: most of them (about 80 to 90%) have aerodynamic diameter below 1 µm (Rissler et al, 2006). In addition, the fraction of incomplete combustion emissions is very significant, especially under burning conditions such as the ones found in open fireplaces, resulting in significant formation of PAHs (Lamberg et al, 2011). It is also well established, that the most carcinogenic PAHs compounds (5-and 6-ring), including BaP, are mostly adsorbed to finer particles (Lin et al, 2008).…”

Over the last years in Greece, the intense use of biomass for space heating resulted in increased ambient and indoor air pollution and enhanced population exposure to particulate matter and genotoxicants in particle and gaseous form such as polyaromatic hydrocarbons (PAHs). This study deals with the precise assessment of exposure to these pollutants and the related health and monetary impact. To these goals, measured and modelled data of outdoor and indoor PM 10 and PM 2.5 were fed into an integrated exposure assessment modelling framework that takes into account indoor air quality, timeactivity patterns of the exposed population and activity-based inhalation rates. Chemical analysis on the sampled PM allowed us to estimate the contribution of biomass burning to PM mass concentration and the associated increase in toxicity (expressed in terms of PAHs content). Health impacts were assessed adapting well-established exposure-response functions coupled with mechanistic exposure models. Monetary cost of these impacts was calculated based on the valuation of the willingness-to-pay/accept to avoid/compensate for the loss of welfare associated with them. PM from biomass burning is finer and more genotoxic than PM from traffic or other urban sources. Total exposure to PM and PAHs due to biomass use was significantly increased and the estimated health burden was increased by more than 40%, while the associated monetary cost rises to ca. €200 m.

“…Among the factors related to wood burning emissions, BBeff has a lower BB / K + ratio (2.4, IQR 1.25-4.2) than BBineff1 (6.0, IQR 2.7-12.0) and BBineff2 (11.6, IQR 6.0-21.0). In wood burning experiments, it was found that OC, EC, PM 10 , and PAH emissions increase relative to the potassium output during non-ideal burning conditions (Lamberg et al, 2011). Zotter et al (2014) found a north-south gradient in levoglucosan / K + and OC nf / K + in Switzerland and hypothesized that it might be linked to the burning conditions.…”

Insights into organic-aerosol sources via a novel laser-desorption/ionization mass spectrometry technique applied to one year of PM<sub>10</sub> samples from nine sites in central Europe

Abstract. We assess the benefits of offline laserdesorption/ionization mass spectrometry in understanding ambient particulate matter (PM) sources. The technique was optimized for measuring PM collected on quartz-fiber filters using silver nitrate as an internal standard for m/z calibration. This is the first application of this technique to samples collected at nine sites in central Europe throughout the entire year of 2013 (819 samples). Different PM sources were identified by positive matrix factorization (PMF) including also concomitant measurements (such as NO x , levoglucosan, and temperature). By comparison to reference mass spectral signatures from laboratory wood burning experiments as well as samples from a traffic tunnel, three biomass burning factors and two traffic factors were identified. The wood burning factors could be linked to the burning conditions; the factors related to inefficient burns had a larger impact on air quality in southern Alpine valleys than in northern Switzerland. The traffic factors were identified as primary tailpipe exhaust and most possibly aged/secondary traffic emissions. The latter attribution was supported by radiocarbon analyses of both the organic and elemental carbon. Besides these sources, factors related to secondary organic aerosol were also separated. The contribution of the wood burning emissions based on LDI-PMF (laser-desorption/ionization PMF) correlates well with that based on AMS-PMF (aerosol mass spectrometer PMF) analyses, while the comparison between the two techniques for other components is more complex.
