A pilot study for indoor and outdoor N02 measurements in Korea was firstly undertaken by using personal samplers during January-February 1984 in Seoul. This study was attempted to assess the N02 levels inside building offices and selected outdoor areas and to compare the measurements monitored by different personal samplers. The mean N02 concentrations in offices measured by filter badge sampler were -32.6 ppb, while the corresponding levels, measured by passive diffusion tube were 40.6 ppb. The use of kerosene heater in offices was associated with a significantly increased level of; N02 measured both by diffusion tube and filter badge samplers. The mean N02 concentrations in main streets exceeded the Korea ambient N02 standard of 50 ppb.
Multiple regression analysis was done to investigate the effects of sampling period, length of stove use, and office size on N02 concentrations. It was significantly shown that office size had the highest contribution ratio for predicting the exposure levels of N02. These findings emphasize the potential importance of indoor sources and characteristics of office building structures in determining indoor N02-levels. These results from a pilot study stress: the need to investigate further research of indoor pollution problems in Korea in the future.
