“…Independent of the choice of detection method, several general trends can be observed from ambient measurements. A small number of existing studies suggest that both in urban and in natural areas, airborne bacterial communities are highly diverse, and variations in their species diversity are more complex than had previously been supposed (Bovallius et al, 1978;Jones and Cookson, 1983;Chihara and Someya, 1989). Bacterial diversity in rural areas is generally higher than at urban sites (Despre´s et al, 2007).…”

“…Bacterial diversity in rural areas is generally higher than at urban sites (Despre´s et al, 2007). Still, the concentration of bacteria seems often to be higher in urban than in rural environments (Bovallius et al, 1978;Chihara and Someya, 1989;di Giorgio et al, 1996;Shaffer and Lighthart, 1997;Fang et al, 2007;Fahlgren et al, 2010), even when the samples are taken in the same geographic region. However, opposite trends have also been found: For example, Rosas et al (1993) described that bacterial concentrations in rural environments are higher than in urban sites.…”

“…However, opposite trends have also been found: For example, Rosas et al (1993) described that bacterial concentrations in rural environments are higher than in urban sites. There is also evidence that the bacterial concentrations in the urban environment are influenced by human activities (Bovallius et al, 1978;Fang et al, 2007). Different cities do vary in their bacterial composition and abundance (Brodie et al, 2007); thus, there can be no single, typical description of urban bacterial composition.…”

“…Measurements show that mean concentrations in ambient air can be greater than 1 )10 4 cells m (3 over land (Bauer et al, 2002a), whereas concentrations over the sea may be lower by a factor of Â100 Á 1000 (Prospero et al, 2005;Griffin et al, 2006). Airborne bacteria may be suspended as individual cells but are more likely to be attached to other particles, such as soil or leaf fragments, or found as agglomerates of many bacterial cells (Bovallius et al, 1978;Lighthart, 1997). For this reason, whereas individual bacteria are typically on the order of Â1 mm or less in size, the median aerodynamic diameter of particles containing culturable bacteria at several continental sites has been reported to be Â4 mm, whereas at coastal sites it is Â2 mm (Shaffer and Lighthart, 1997;Tong and Lighthart, 1999;Wang et al, 2007).…”

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.

“…One of these concerns the microbiological aspects of such large movements of dust and the role of rainfall in its deposition. Particulate microorganisms in air have been broadly studied [4,12]. A statistical correlation between the presence of desert dust and observed increases in the number of colony forming units (cfu) has also been reported [10,12,13].…”

In order to determine the presence of Fusarium spp. in atmospheric dust and rainfall dust, samples were collected during September 2007, and July, August, and October 2008. The results reveal the prevalence of airborne Fusarium species coming from the atmosphere of the South East coast of Spain. Five different Fusarium species were isolated from the settling dust: Fusarium oxysporum, F. solani, F. equiseti, F. dimerum, and F. proliferatum. Moreover, rainwater samples were obtained during significant rainfall events in January and February 2009. Using the dilution-plate method, 12 fungal genera were identified from these rainwater samples. Specific analyses of the rainwater revealed the presence of three species of Fusarium: F. oxysporum, F. proliferatum and F. equiseti. A total of 57 isolates of Fusarium spp. obtained from both rainwater and atmospheric rainfall dust sampling were inoculated onto melon (Cucumis meló L.) cv. Piñonet and tomato (Lycopersicon esculentum Mill.) cv. San Pedro. These species were chosen because they are the main herbaceous crops in Almeria province. The results presented in this work indicate strongly that spores or propagules of Fusarium are able to cross the continental barrier carried by winds from the Sahara (Africa) to crop or coastal lands in Europe. Results show differences in the pathogenicity of the isolates tested. Both hosts showed root rot when inoculated with different species of Fusarium, although fresh weight measurements did not bring any information about the pathogenicity. The findings presented above are strong indications that long-distance transmission of Fusarium propagules may occur. Diseases caused by species of Fusarium are common in these areas. They were in the past, and are still today, a problem for greenhouses crops in Almeria, and many species have been listed as pathogens on agricultural crops in this region. Saharan air masses dominate the Mediterranean regions. The evidence of long distance dispersal of Fusarium spp. by atmospheric dust and rainwater together with their proved pathogenicity must be taken into account in epidemiological studies.
