| Abstract |
In this study, we investigated the densities of HCHO and TVOC emissions polluting the indoor air in newly-built apartment houses. We used on-site measurements, as well as compared and analyzed the changes in the amount of emissions of indoor air-polluting materials according to indoor closing materials through experiments using small chambers. (1) The results from on-site measurement of newly-built apartment houses indicated that the amount of HCHO emission remained below the environmental standards, whereas the amount of TVOC emission exceeded that of the environmental standard value (500 μg/m3), at a high of 79.2 m2 and 105.6 m2, and a low of 141.9 m2. (2) According to the results of the analysis of the amount of emitted pollutants in indoor closing materials through small chamber experiments, the emitted amount of pollutants in all the closing materials reached the highest point on the date of installation, and which gradually decreased for the succeeding 10 days. Therefore, it would be necessary for residents to move into the apartments at least 10 days after indoor closing materials are installed in the site concerned. |
