AbstractAbstract PDF
For the purpose of preparing the fundamental data on air pollution in underground shopping center and also contributing to the health improvement of resident, the authors measured the level of SO2, NO2, TSP, CO, CO2 and also some related factors as air temperature, air movement, relative humidity and mean radiation temperature at inside and outside of underground shopping center in Pusan from January to February and from July to August 1994. The results were as follows: 1. The mean concentration of CO within the underground shopping center was 3.1+/-1.3ppm in winter and 2.1+/-0.9 ppm in summer. There was a negative correlation (p<0.01) between inner CO concentration and temperature in summer and no correlation between inner CO concentration and outer CO concentration in underground shopping center 2. The mean concentration of C02 within the underground shopping center was 876+/-353 ppm in winter and 757+/-125 ppm in summer. There was a negative correlation (P<0.01) between inner CO2 concentration and air movement in summer and positive correlation (p<0.05) between inner CO2 oncentration and outer CO2 concentration in underground shopping center. 3. The mean concentration SO2 within a underground shopping center was 0.036+/-0.019ppm in winter and 0.040+/-0.013ppm in summer. There was a positive correlation(p<0.01) between inner SO2 concentration and positive correlation between inner SO2 concentration and outer SO2 concentration in summer and winter in Underground shopping center. 4. The mean concentration of NO2 within a underground shopping center was 0.052+/-0.038ppm in winter and 0.042+/-0.016ppm in summer. There was a no correlation between inner NO2 concentration and thermal factors in summer and winter and low correlation between inner NO2 concentration in underground shopping center. 5. The mean concentration of TSP within a underground shopping center was 430+/-214 microgram/m3 in winter, 366+/-73 microgram/m3 in summer, and very in excess of the atmospheric environmental quality standards of Korea(150 microgram/m3). There was low correlation between inner TSP concentration and temperature in summer and high correlation between inner TSP concentration and outer TSP concentration in underground shopping center.
