Abstract
Human health damage by exposure of toxic chemicals in indoor environments is called as “sick house syndrome” or “chemical super-sensitivity”, which is caused by toxic principles with low or detectable concentrations. Recently, this disease has gradually increased in Japan. The causal toxic chemicals are considered to come from several house materials, such as wallpaper, ceiling, curtains, carpets, furniture, electrical appliances, and so on. Thus, the Minister of Health, Labour and Welfare manages to introduce air quality guidelines for indoor air pollutants in order to prevent human health damage from such toxic chemicals.
