Abstract
In this study, formaldehyde concentrations in two exhibition halls were monitored using a passive sampler from May 2012 to April 2013. Formaldehyde concentrations in the exhibition halls were 5 to 36 times higher than concentrations outdoors. Concentrations inside the exhibition room and showcase varied according to pollutant source, HVAC(heating, ventilation, air conditioning)system and environment management. The formaldehyde concentration levels were corrected according to a standard method prescribed by Indoor Air Quality Management Law of the Ministry of Environment, Korea. As a result, Most concentration levels exceeded the exhibition standard of the Ministry of Environment($100{\mu}g/m^3$) and artifacts conservation standard of Tokyo National Museum($50{\mu}g/m^3$). Seasonal concentrations in the exhibition room and showcase were in the order summer>fall>spring>winter. Formaldehyde emissions increased in summer when air temperature and relative humidity are both high. Formaldehyde concentration distribution according to the temperature and relative humidity showed positive correlation. Air temperature showed good correlation because $R^2$ was in the range of 0.8~0.9. Analysis of formaldehyde emission characteristics in the exhibition hall would be helpful in efforts to improve indoor air quality.
