In order to propose the fundamental data for control of formaldehyde pollution and to contribute health improvement of residents in Pusan area by assessing the formaldehyde level in underground shopping center, anthors measured HCHO, temperature,
moisture and TSP level at the 5 shopping centers by site and time from July to August 1990.
@ES The obtained results were as follows:
@EN 1. The mean concentration of formaldehyde in the underground shopping center was 88.13±30.94ppb four times higher than that of ambient air which was 21.17±9.69ppb(p<0.0000).
2. The mean concentration of formaldehyde in the underground shopping center by measuring time was night , afternoon, and morning in descending oder (p<0.01).
3. The mean concentration of formaldehyde in the underground shopping center by place was Pujion4. As a result of correlation analysis, relationship between formaldehyde concentrations and temperature showed a negative correlation (p<0.01) but temperature and TSP (p<0.01). temperature and humidity (p<0.05) showed a positive correlation.
5. The mean level of temperature, moisuture and TSP in the underground shopping center was 29.±2℃, 76±14%, 131±53㎍/㎥, respectively.
