Bioaerosol that is transported together with yellow dust can cause serious damage to human health. We conduct high-altitude atmospheric observation surveys around Asia, collect samples of microorganisms that are floating in the atmosphere, and develop databases on species composition and potential functions. We clarify the affect of microorganisms isolated in the atmosphere on the aggravation of allergies, infectious diseases, and organs diseases, and conduct analyses on the degree of health damage. The project will launch an atmospheric monitoring base on the Noto Peninsula targeted at highly pathogenic bacteria to enable predictions of the wind spreading route of infectious microorganisms, and contribute to the formulation of environmental policy and strategy and the development of preventive technologies in response to atmospheric infections.
