“…Fine atmospheric particles (D p b 1.0 μm) have become a major public health concern (Kan et al, 2012;Lazaridis et al, 2002;Sheppard et al, 1999). Sea spray, dust, wildfires, secondary biogenic organic and secondary inorganic matter are the dominant aerosol types on a global scale (Bauer et al, 2004;Hoyle et al, 2011;Kaufman et al, 2002;Spracklen et al, 2009;Vignati et al, 2010;Voutsa et al, 2014), while in urban areas, one of the main primary sources of atmospheric PM is road traffic (Byčenkienė et al, 2014;Bressi et al, 2014;Cao et al, 2011;Huang et al, 2014;Wehner et al, 2002;Zhu et al, 2002), with diesel vehicles in particular being associated with higher emissions of fine and ultrafine particles. Numerous studies demonstrated that biomass burning, either of wildfire or domestic fuel origin, can be a significant contributor to the primary sources as well (Alves et al, 2011;McMeeking et al, 2009;Puxbaum et al, 2007;Ryu et al, 2007;Ulevicius et al, 2010).…”
