摘要:Data on the indoor environment, especially in relation to the sick building syndrome (SBS), were collated. SBS problems have increased since the 1990s in Japan. A range of legislation has however been introduced and manufacturers of architectural and construction materials have made efforts to improve. As a result, the concentration of volatile organic compounds (VOC) in indoor air has recently shown a decreasing tendency. However, even if the concentration in indoor air falls below the guideline value set by the Ministry of Health, Labour and Welfare, the SBS problem may not be completely resolved. Attention also needs to be paid to other materials not subject to guideline values. Especial consideration needs to be given to people in high-risk groups sensitive to chemical exposure, such as patients with multiple chemical sensitivity, children, the elderly, and expectant mothers.
