Simultaneous air monitoring inside and outside of the selected Korean homes in an industrial area during winter (Jan--Feb) and summer (Jul--Aug) 1997 were performed for PM2.5 and acidic element using the annular denuder system (ADS). Eight homes were selected as part of the residential air monitoring program established for a study of risk assessment of air pollution conducted by the Korea Ministry of Environment (KMOE). The data set was collected on two different days with a 24h sampling period (from 10:00 a.m. to 10:00 a.m. the next day) during the sampling period. Chemical species including HNO{sub 3}, HNO{sub 2}, SO{sub 2}, NH{sub 3}, NH{sub 4+}, nitrate, and sulfate were available for comparisons of indoor and outdoor aerosol samples collected at the homes. The pattern of house-specific indoor mean concentrations, seasonal differences of indoor and outdoor concentrations, indoor/outdoor ratios, and probable sources of indoor aerosols are discussed. Preliminary results suggest that indoor aerosol appears to be affected by infiltration of outdoor air as well as by indoor generations. Heating and cooking practices, coupled with generally inadequate ventilation also were shown to influence indoor air quality.
