Nitrogen dioxide (NO2) has been regarded as one of the main elements among air pollutants, and we measured NO2 levels of near gas range, kitchen, living room and outdoor on 489 apartments in Pusan area. NO2 were sampled by using Palmes tubes (diffusion tube sampler) during August 16-25, 1995 (summer) and January 15-29, 1996 (winter), respectively.
Authors wanted to know comparison of NO2 levels in summer and winter, NO2 levels categorized by variables, and variables affected to NO2 levels. According to this study, we conducted to establish the degree of indoor-outdoor air pollution of urban apartments in Korea and methods to reduce indoor air pollution.
The results of this study were summarized as follows:
1) Mean NOz levels of near gas range, kitchen, living room, and outdoor were 25. 910.0 ppb, 23.38.0 ppb, 19.96.1 ppb, and 19.0+6.0 ppb, in summer, and 34. 5 16.8 ppb, 28.2 13.4 ppb, 25.3 12.5 ppb, 21.8 9.8 ppb in winter, respectively.
2) Mean NO2 levels according to the floor levels were not significantly different in summer, and in winter, NO2 levels were decreased as the floor levels were increasing, but those were increased above 16th floor.
3) Variables showing significant correlation(p(0,05) with NO2 ´evels were as follows; Summer: floor level, family size, number of family during a m´i ~al, number using gas range during rice cooking per day, and natural ventilation.
Winter: floor level, family size, number of person who have! been respiratory disease in a house, number of family during a meal, total number of meals, and number using gas range during rice or side-dish cooking per day.
4) We suggest that the methods of reducing indoor NO2 level´s are ventilation dur-
ing cooking, complete combustion, decreasing number and time !of cooking, and substitution of fuels.
