Outline of Final Research Achievements

Asian dust events occurring over East Asia dispersal airborne microorganisms (bioaerosol), which would impact biological ecosystems and human societies in downwind area such as Japan and Korea. However, the microbial long-range transports process has rarely been investigated because large-scale sampling network over eastern Asia were needed. Our Japan-China-Korea survey network collected the bioaerosol samples at height altitudes (1000m-3000m) at Asian dust source and deposition regions. Metagenomic analysis targeting microbial rRNA genes revealed that the microbial communities associate with Asian dust were originated from terrestrial, marine, phyllophiric environments. Furthermore, the microbial effects of human health, such as allergy and asthma, have been demonstrated by the mouse assay using fungal isolates. These informative results would contribute to develop the global hazardous measures for the long-range transported pathogens by Asian dust events and industrial pollutants.
