“…Dry-discharged spore concentrations tend to be enhanced during warm, dry weather conditions, whereas actively wet discharged spores tend to be enhanced during humid conditions such as those at night and in the early morning hours (Graham et al, 2003;Elbert et al, 2007). Emission and dispersal of fungal spores can thus be selectively correlated with various meteorological parameters and usually have specific behaviours, depending on the species involved (Fitt et al, 1989;Pasanen et al, 1991;Calderon et al, 1995;Katial et al, 1997;Sabariego et al, 2000;Troutt and Levetin, 2001;Burch and Leventin, 2002;Jones and Harrison, 2004;Grinn-Gofron and Mika, 2008;Oliviera et al, 2009).…”

“…Certain fungal spores and other PBAP classes can be highly coloured and absorbing, which may increase their direct influence on the surrounding atmosphere (e.g. Adams et al, 1968;Troutt and Levetin, 2001). However, there have been very few studies estimating the direct effect of PBAP on climate, in part because geographically or temporally comprehensive PBAP measurements are not yet available.…”

A B S T R A C T Atmospheric aerosol particles of biological origin are a very diverse group of biological materials and structures, including microorganisms, dispersal units, fragments and excretions of biological organisms. In recent years, the impact of biological aerosol particles on atmospheric processes has been studied with increasing intensity, and a wealth of new information and insights has been gained. This review outlines the current knowledge on major categories of primary biological aerosol particles (PBAP): bacteria and archaea, fungal spores and fragments, pollen, viruses, algae and cyanobacteria, biological crusts and lichens and others like plant or animal fragments and detritus. We give an overview of sampling methods and physical, chemical and biological techniques for PBAP analysis (cultivation, microscopy, DNA/RNA analysis, chemical tracers, optical and mass spectrometry, etc.). Moreover, we address and summarise the current understanding and open questions concerning the influence of PBAP on the atmosphere and climate, i.e. their optical properties and their ability to act as ice nuclei (IN) or cloud condensation nuclei (CCN). We suggest that the following research activities should be pursued in future studies of atmospheric biological aerosol particles: (1) develop efficient and reliable analytical techniques for the identification and quantification of PBAP; (2) apply advanced and standardised techniques to determine the abundance and diversity of PBAP and their seasonal variation at regional and global scales (atmospheric biogeography); (3) determine the emission rates, optical properties, IN and CCN activity of PBAP in field measurements and laboratory experiments; (4) use field and laboratory data to constrain numerical models of atmospheric transport, transformation and climate effects of PBAP.

“…This finding is consistent with our previous study of Adhikari et al (2005) conducted in the Greater Cincinnati area, in which the outdoor airborne concentration of fungi was shown to be significantly affected by temperature while the correlation between concentration of airborne fungi and relative humidity were neither statistically significant nor strong. It may be because certain types of fungal spores including Cladosporium, Alternaria, and Epicoccum belong to dry-air spora that generally exhibits the highest concentration in the atmosphere with low humidity condition, while the others such as Ascospores and Basidiospores belong to wet-air spora that requires moisture for spore release Troutt and Levetin, 2001). Thus, different fungal species react differently to the air humidity changes, while the air temperature affects the dispersal of different species in a similar way.…”

In this study, the culturability of indoor and outdoor airborne fungi was determined through longterm sampling (24-h) using a Button Personal Inhalable Aerosol Sampler. The air samples were collected during three seasons in six Cincinnati area homes that were free from moisture damage or visible mold. Cultivation and total microscopic enumeration methods were employed for the sample analysis. The geometric means of indoor and outdoor culturable fungal concentrations were 88 and 102 colony-forming units (CFU) m -3 , respectively, with a geometric mean of the I/O ratio equal to 0.66. Overall, 26 genera of culturable fungi were recovered from the indoor and outdoor samples. For total fungal spores, the indoor and outdoor geometric means were 211 and 605 spores m -3 , respectively, with a geometric mean of I/O ratio equal to 0.32. The identification revealed 37 fungal genera from indoor and outdoor samples based on the total spore analysis. Indoor and outdoor concentrations of culturable and total fungal spores showed significant correlations (r = 0.655, p<0.0001 and r = 0.633, p<0.0001, respectively). The indoor and outdoor median viabilities of fungi were 55% and 25%, respectively, which indicates that indoor environment provides more favorable survival conditions for the aerosolized fungi. Among the seasons, the highest indoor and outdoor culturability of fungi was observed in the fall. Cladosporium had a highest median value of culturability (38% and 33% for indoor and outdoor, respectively) followed by Aspergillus/ Penicillium (9% and 2%) among predominant genera of fungi. Increased culturability of fungi inside the homes may have important implications because of the potential increase in the release of allergens from viable spores and pathogenicity of viable fungi on immunocompromised individuals.

“…However, the majority of these efforts have more frequently aimed at the prediction of airborne pollen count; advanced forecasting models of airborne fungal spore circulation are comparatively few (Katial et al 1997), and most of them usually display low predictability (AnguloRomero et al 1999;Mitakakis et al 2001;Troutt & Levetin, 2001;Stennett & Beggs, 2004).…”

“…The dispersal and transport of airborne fungal spores -and therefore the predictive power of created statistical models -are influenced by several meteorological factors, such as wind, rainfall and air temperature components, atmospheric pressure, solar radiation, and relative humidity (Solomon, 1978;Hjelmroos, 1993;Katial et al 1997; Kurkela, 1997;Angulo-Romero et al 1999;Corden & Millington, 2001;Mitakakis et al 2001;Munuera Giner et al 2001;Troutt & Levetin, 2001;Stennett & Beggs, 2004). Nevertheless, the exact relationship of spore counts and meteorological factors is not thoroughly understood.…”
