Abstract
This study was conducted at a Terminal, a Parking Lot, an Underground shopping center, a Funeral hall and a Hospital waiting room of Cheon An area in August 2008 to examine the concentration level of HCHO(formaldehyde). The concentration level of the remodeled sites were $39.4\;{\pm}\;12.0\;{\mu}g/m^3$ in the terminal, $32.7\;{\pm}\;7.3\;{\mu}g/m^3$ in the parking, and $97.8\;{\pm}\;29.4\;{\mu}g/m^3$ in the underground shopping center. The underground shopping center had the highest level and followed by the terminal and the parking. On the contrary, the site remodeling had the level of $17.7\;{\pm}\;12.4\;{\mu}g/m^3$ in the funeral hall and $17.9\;{\pm}\;0.6\;{\mu}g/m^3$ in the hospital waiting room. The funeral hall had highest level than that of the hospital waiting room. Both the remodeled sites and the not remodeled site had concentration level of HCHO below the standard level, but it was higher in the remodeled sites. There were no relations among the HCHO, the temperature and the humidity in facilities of Cheon An area.
