The measured results on the concentration of volatile organohalogen compounds in actual buildings and their risk assessments are described. The measurements were conducted in 14 houses, 5 laundries, 4 indoor swimming pools and 4 office buildings. Analysis of chloroform, carbon tetrachloride, 1,1,1-trichloroethane, etc. by ECD gas chromatography showed that the concentrations of the total halogen compounds in 2 of the 17 living rooms were higher than 30 μg/m^3 as proposed in the guidelines of WHO. A higher concentration of the total halogen compounds in the bathrooms was observed than in the living rooms. In the newly-built houses a lower concentration was observed. Regarding each compound, a high concentration of trichloroethylene was observed in the bathrooms, that of tetrachloroethylene in the laundries, and that of chloroform in the indoor swimming pools. As the results of the risk assessment the annual mortality of the air in the houses ranged from 2.5*10^<-6> to 7.1*10^<-5>.
