A model test room was built with finish flooring of solid oak and wall paneling of sugi wood. Concentration of carbonyl compounds and volatile organic compounds (VOCs) in the indoor air of the test room were measured over one year. The following results were obtained : (1) The main compounds emitted were formaldehyde and acetaldehyde_ The emission of formaldehyde was greatly dependent on room temperature and did not easily attenuated although the emission was low throughout the test period. On the other hand, the emission of acetaldehyde was high at the beginning, but decreased rapidly in the first two weeks and did not depend on temperature. (2) The main VOC constituents were terpenoids, especially a-pinene. The terpenoids were rapidly attenuated and diminished within three to four months.
