“…This may be explained by the hypothesis that there are no barriers for algae to transport by wind and water-wind flows, which move them over great distances and as a result, they can settle on various substrates, reservoirs and groundwater wells [27] . To a lesser extent, the algae are delivered from water reservoirs by strong wind, which could be able to blow off liquid drops from wave peaks [28,29] . Therefore, the presence of some species of cyanobacteria in both surface and ground waters might occur by wind from the same source "soil", or occur by transfer of these species by water-wind flows from surface water to groundwater wells.…”

“…Therefore, the presence of some species of cyanobacteria in both surface and ground waters might occur by wind from the same source "soil", or occur by transfer of these species by water-wind flows from surface water to groundwater wells. In this respect, Dubovik [29] , demonstrated the carrying of some species of cyanobacteria with rainwater flows to rainwater puddles. This may reflect the capability of these species to populate any place, as tree trunks, granite, marble and buildings.…”

Abstract. Cyanobacteria were surveyed in six surface water bodies and six ground water wells in Asir region, Southwest of Saudi Arabia between August and December 2003. A total of 25 cyanobacterial species belonging to 16 genera were identified during this study. Most species showed wide range in their distribution among all surface and ground water sites. However, three species were recorded in all surface water sites, but not found in ground water sites. Two species were found only in all ground water sites. The results also showed that some species were restricted only to a certain site. Compared to the results of previous studies reported on freshwater cyanobacteria in Saudi Arabia, fifteen cyanobacterial species were identified as new records for Saudi Arabia during this study. Because of their ability to produce toxins, cyanobacteria should be monitored in surface and ground waters in Saudi Arabia in order to avoid their harmful effect on plant, animal and human health upon exposure to these waters.

“…These algae are termed terrestrial, aeroterrestrial, aerophytic or subaerial, are able to reside on almost all substrates, natural or artificial and can become airborne, constituting the aero-(phyto) plankton. Chlorophycean and xanthophycean species are common worldwide (Printz, 1921;Laundon, 1985;Dubovik, 2002;Reisser, 2002;Sharma et al, 2007;Neustupa and Skaloud, 2010) and exist free living as well as lichenised (Bubrick et al, 1984). Due to the size of the algae and their spores, many smaller than 10 mm in diameter (Printz, 1921;Dubovik, 2002;Burchardt and Dankowska, 2003;Neustupa and Skaloud, 2010), they can be easily dispersed in the atmosphere.…”

In a recent review article, the mechanisms involved in the aerosolisation of algae were presented, and Sharma et al (2007) stated that 'airborne algae are the least-studied organisms in both aerobiological and phycological studies'.…”

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.

“…Contamination of groundwater with microorganisms including cyanobacteria can occur from infiltration near rivers, lakes, ponds [1]. Rainfall events can also play a role in the migration of algae and their products into the groundwater [2]. Once algae or algal spores enter groundwater wells, they can find suitable conditions (e.g.…”
