This study was conducted to survey the current status of indoor air pollutants in 40 offices and the prevalence on subjective symptoms related with indoor air quality(IAQ) for 1,395 office workers from July to September, 2004 in Seoul,
Busan, and Suncheon Cities and Gyeonggi District. The mean concentrations of carbon dioxide, volatile organic
compounds, formaldehyde, bacteria and respirable dust in offices were 574.8 ± 230.1 ppm, 698.2 ± 944.7 ㎍/m3, 56.9
± 37.2 ㎍/m3, 203.1 ± 135.1 CFU/m3, 60.9 ± 47.6 ㎍/m3, respectively. It was investigated the excess rate for standards or guidelines of indoor air quality on the Ministry of Labor or the Ministry of Environment in Korea were 2.5% in carbon dioxide, 20.2% in volatile organic compounds, 7.5% in formaldehyde, and 1.3% in respirable dust, respectively. The prevalence of ’headache’, ’fatigue’, and ’lazy’ among the subjective symptoms related with IAQ showed very high percentage. With the above considerations in mind, it is suggested that the researches for indoor air quality in offices should be expanded and the health risk assessment be performed to offer scientific data for decision-making of policy for improvement and management of indoor air quality in office.
