The purpose of this study is to accumulate long term field-measurement data of the concentration of formaldehyde(HCHO) and volatile organic compounds(VOCs) found in indoor air, and to investigate the behavior of these concentrations. In addition, we studied the lifestyle and any symptoms of the occupants. The duration of the field measurements was 1996-1999(HCHO) and 1996-1998(VOCs). The results showed that a higher concentration of HCHO was detected during the heat of the summer. decreasing as temperatures decreased. While each summer showed a fluctuation in these levels, over a four year period, there was an overall decline in the concentration. A high concentration of total volatile oreranic compounds (TVOC) was detected in newly constructed houses. All of the TVOC concentrations exceeded the interim target level and the VOCs components were influenced by the habits and lifestyles of the occupants. We did not find any association between the concentration of HCHO or the VOCs in the indoor air and the symptoms experienced by the occupants.
