| Outline of Final Research Achievements |
The time trends regarding health status of residents and changes in environmental quality of housing were systematically compared between water-damaged homes after flooding. A questionnaire survey was conducted on the physical and psychological conditions associated with the exposure to water damage in homes. The influence of various environmental risk factors, particularly housing-related variables on public health and hygiene was also examined. Moreover, airborne microbial matter and volatile organic compounds in the water damaged houses and fungi on the surface of under floors were measured.
In order to clarify indoor climate in a crawl space after flooding, long-term experiment using a test house was performed. Tap-water was supplied to 100mm depth on a crawl space in each room, and after 72 hours it drained. Indoor humidity and water contents of wood and concrete in a crawl space were analyzed from the view point of moisture balance in a crawl space after flooding.
