e at affe igat w ari usty le b te s 10 ourc results suggest Asian dust is one of the processes for dispersal of airborne bacteria in the global atmosphere. ect and climat firmed an dus o et al. ffin, 2 rchant, een of ownw ciated with African dust in the Caribbean atmosphere and reported that culturable bacterial concentrations in dust and non-dusty air were 105 and 13 CFU m3, respectively. Choi et al. (1997) and Jeon et al. (2011) collected air samples during Asian dust and non-dust periods in the Republic of Korea, and their results showed that culturable bacterial concentrations in dust were approximately to evaluate bacterial abundances in the air with culture methods (Peccia and Hernandez, 2006). Recent laboratory experiments also revealed that ultraviolet irradiation could kill viable bacteria even in an endospore state, suggesting that viable bacteria emitted into the atmosphere might become non-viable during their dispersal (Smith et al., 2011). Thus information on bacterial abundance and viability is necessary to estimate their influences onpublic health, downwind ecosystems and atmospheric phenomena (Griffin, 2007; Hoose et al., 2010; Ichinose et al., 2008)
