Abstract

In Japan, the number of people impacted by asthma, allergy and atopic dermatitis has been increased yearly. In order to clarify the actual condition of indoor microorganisms in residences, a field survey on airborne fungus and house dust mite allergen concentrations was conducted in twenty-five residences in Japan during winter. Concerning Der1 concentrations, half of the residences exceeded 2?g/g dust. For airborne fungus, the concentrations of Penicillium and the total airborne fungus in the residences adopted natural ventilation system were significantly higher than that of mechanical system. Indoor humidity was significantly associated with an increase of the level of airborne fungus concentrations.
