Abstract
A survey of indoor and outdoor air pollution by aldehydes and ketone in August 1999, in the city of Fuji was performed. Sampling was performed by using Sep-Pak XPoSure. Target compounds were extracted with dichloromethane, and analyzed by HPLC. Almost all aldehydes and ketone could be detected in indoor and outdoor air. All target aldehyde and ketone concentrations in indoors were higher than those outdoors. Formaldehyde concentrations in new houses were higher than those in old ones. Concentrations of almost all aldehydes including formaldehyde in the room where the floor was covered with tatami mat were lower than those with a carpet or nothing at all. Formaldehyde concentrations of two of 21 houses (10%) exceeded the indoor air quality guideline (100 μg/m3) of the Ministry of Health and Welfare, Japan. Correlations between 10 target aldehydes were significant.
