“…During late summer, spores from fungi are most intensively emitted. Bauer et al (2002) reported the diameters of smallest fungal spores of 2 µm, underlining their presence in the coarse sizes (i.e., 2.0-3.3, 3.3-7.0, >7.0 µm). They are also major soluble components in the bark of trees, branches and leaves (Medeiros et al, 2006).…”

Abstract.To better understand the size-segregated chemical composition of aged organic aerosols in the western North Pacific rim, day-and night-time aerosol samples were collected in Sapporo, Japan during summer 2005 using an Andersen impactor sampler with 5 size bins: D p <1.1, 1.1-2.0, 2.0-3.3, 3.3-7.0, >7.0 µm. Samples were analyzed for the molecular composition of dicarboxylic acids, ketoacids, α-dicarbonyls, and sugars, together with water-soluble organic carbon (WSOC), organic carbon (OC), elemental carbon (EC) and inorganic ions. Based on the analyses of backward trajectories and chemical tracers, we found that during the campaign, air masses arrived from Siberia (a biomass burning source region) on 8-9 August, from China (an anthropogenic source region) on 9-10 August, and from the East China Sea/Sea of Japan (a mixed source receptor region) on 10-11 August. Most of the diacids, ketoacids, dicarbonyls, levoglucosan, WSOC, and inorganic ions (i.e., SO 2− 4 , NH + 4 and K + ) were enriched in fine particles (PM 1.1 ) whereas Ca 2+ , Mg 2+ and Cl − peaked in coarse sizes (>1.1 µm). Interestingly, OC, most sugar compounds and NO

“…The large surface area of snowflakes leads to an efficient scavenging and removal of atmospheric pollutants (Chang, 1984;Barrie, 1991;Lei and Wania, 2004), which then end up in the snow cover. The snowpack of the High Arctic archipelago of Svalbard is characterized by the dominance of sea salt in its solute (Hodgkins and Tranter, 1998) and with a bacterial content that is slightly higher than in Alpine regions (Sattler et al, 2001;Bauer et al, 2002;Amato et al, 2007). Due to the archipelago's remote location, small human population, and scarce local pollution sources, the region acts as a sink for atmospheric contaminants from long-range transport (Rahn et al, 1980;Stohl, 2006;Hirdman et al, 2010).…”

“…As for mineral aerosols, micro-organisms originate from sources and during seasons that are associated with their specific habitats. This gives rise to the important spatial and temporal variability of quantities of micro-organisms in the air (Bauer et al, 2002;Ross et al, 2003;Sattler et al, 2001). …”

“…The higher concentrations of bacteria observed in the summer (JulyAugust) over two agricultural sites in Oregon (USA) may reflect the flux from agricultural sources and activities and dry dusty soil conditions at this time of the year (Tong and Lighthart, 2000). Even on the scale of a single day, the airborne spore concentration increased from 20 000 spores/m 3 to 170 000 spores/m 3 in a 2-h period in the area around Tulsa, Oklahoma (USA) (Burch and Levetin, 2002). Diurnal periodicity has also been observed (Lindemann and Upper, 1985;Tong and Lighthart, 2000).…”

Abstract. For the past 200 years, the field of aerobiology has explored the abundance, diversity, survival and transport of micro-organisms in the atmosphere. Micro-organisms have been explored as passive and severely stressed riders of atmospheric transport systems. Recently, an interest in the active roles of these micro-organisms has emerged along with proposals that the atmosphere is a global biome for microbial metabolic activity and perhaps even multiplication. As part of a series of papers on the sources, distribution and roles in atmospheric processes of biological particles in the atmosphere, here we describe the pertinence of questions relating to the potential roles that air-borne micro-organisms might play in meteorological phenomena. For the upcoming era of research on the role of air-borne micro-organisms in meteorological phenomena, one important challenge is to go beyond descriptions of abundance of micro-organisms in the atmosphere toward an understanding of their dynamics in terms of both biological and physico-chemical properties and of the relevant transport processes at different scales. Another challenge is to develop this understanding under contexts pertinent to their potential role in processes related to atmospheric chemistry, the formation of clouds, precipitation and radiative forcing. This will require truly interdisciplinary approaches involving collaborators from the biological and physical sciences, from disciplines as disparate as agronomy, microbial genetics and atmosphere physics, for example.
