Recently, indoor air quality in a newly built apartment building has been reported to be in a dangerous condition. But, Building Materials are composed of very complex chemical compounds which emission very much VOCs. This study focused on the emission rate of the construction materials. The method of study is as follows. First, validation of small chamber method to determine emission rate of construction material was performed by Correlation Analysis(SPSS 12.0). Second, the construction materials were categorized by their feature and the emission rate of volatile organic compound was determined. Totally, VOCs emission rate of 147 materials were determined. On the basis of the measurement results achieved, we can estimate emission characteristic of the pollutant from finishing materials. In the present case of TVOC, detected VOCs is the subject of the study range from n-hexane to n-hexadecane, and there is a somewhat discrepancy with a practice hazard material due to converted total sum of each toluenes. So, it is needed to make a plan to regulate emission intensity of hazardous material individually that is detected a large amount except for non-hazardous or rarely detectable materials.
