This study was conducted to estimate the properties of nitrogen dioxide levels and health risk. The nitrogen dioxide levels were measured for residents of a study group(industrial area within 5km) and a control group (15km farther), respectvely using the nitrogen dioxide filter badge forming the passive samper from August, 2006 to September, 2006. The means of indoor, outdoor, work and personal levels of nitrogen dioxide were 34.6511.95mg/m³, 34.8311.78mg/m³, 34.9819.11 and 35.3810.74 respectively in the study area. Mean ratio of indoor to outdoor NO₂ concentration was 0.99. The means of indoor, outdoor and personal level of nitrogen dioxide were 23.667.19mg/m³, 18.224.06mg/m³ and 27.2718.93㎍/m³ respectively in the control area. Mean ratio of indoor to outdoor NO₂ concentration was 1.39. People spent 80.9% of their time in indoor at the study area and 76.9% at the control area. The percentages of time spent in outdoor were 14.9% and 20.9% at the study area and the control area respectively. The percentages of time spent in car were 4.2% and 2.2% in study area and control area respectively. The levels of indoor, outdoor, workplace nitrogen dioxide in the study area and the control area were found below the permissible level of health-hazardous effects.
