This study was performed to get the fundamental data establishing environmental formaldehyde threshold limit as well as to contribute the health promotion of merchants and customers in two underground shopping-centers in Taejon from Dec. 1997 to Jan. 1998.
Formaldehyde concentration and three climate factors-air current, humidity, and temperature-were measured at exit., hallway and inside shops in underground environment, and questionnaire about 15 subjective symptoms among 120 merchants in the inside shops were also surveyed by means of the questionnaire for screening workers exposed formaldehyde in Korea.
The results were as follows ;
1. The average formaldehyde concentration in whole area was 0.0299 ppm ; Exit, Hallway and Inside shop were 0.0205 ppm, 0.0325 ppm and 0.0366 ppm, respectively(p<0.000).
2. According to simple regresson analysis, air current(r=-0.2517, p<0.05) and temperature(r=0. 5871, p<0.001) were significantly related to formaldehyde concentration.
3. More than 80% of the merchants have 5 subjective symptoms such as easy fatigahility, headache, throat discomfort, conjunctival injection, and nasal congestion.
With all above the results, it can be suggested that environmental formaldehyde threshold limit at underground in Korea be reestablished, regarding related climate factor-air current and temperature-, and the questionnaire for screening subjective symptoms should be developed again for evaluating the evironmental effect of formaldehyde.
