【 摘 要 】

Levels of indoor nitrogen dioxide (NO₂) in a home equipped with butane gas stove andheaters are reported between the months of February and July 2003. Diffusion passive sampling wasused for the simultaneous measurements of indoor and outdoor NO₂ concentrations. The overallaverage indoor NO₂ concentrations were 15.6 and 22.3 μg m^-3 for the living room and kitchen,respectively, while that for outdoors was 17.9 μg m^-3. In order to assess the input of indoorcombustion to exchanged outdoor levels of NO₂, the ratios of the living room and kitchen NO₂ valuesto their corresponding outdoor levels were found to be higher in winter than in spring and summer. AnI/O ratio as high as 2.1 detected in winter was attributed to the excess use of butane gas heaters in boththe kitchen and the living room. Other sources and fates of indoor NO₂ are also evaluated. This studywill have significant effects on estimating health risks related to the used of butane gas heaters inresidential homes.
