Recently, concern about Sick House Syndrome (SHS) has been increased in Korea. And it is suspected that formaldehyde (HCHO) and volatile organic compounds (VOCs) are major factors for SHS. This study was surveyed the indoor air quality in new apartments in Korea. The HCHO and VOCs were measured at 90 sites and analysed by HPLC-UV and GC/MS, respectively. The range of HCHO concentrations at 90 sites were 9.39∼248.78㎍/㎥ and the mean value 105.41㎍/㎥ and the concentrations of HCHO at 42 sites (46.7%) exceeded the indoor air quality guideline (100㎍/㎥) in Japan. Among the 4 VOCs, toluene concentrations were the highest and the mean value 127.33㎍/㎥ and that concentrations at 12 sites (13.8%) were exceeded the indoor air quality guideline (260㎍/㎥) in Japan. There was a tendency which the longer the movement and measurement period is, the more the pollutants concentration is decreased. HCHO and VOCs concentrations of domestic results was similar to Japan's survey results in 2000.
