| Abstract |
Most substances polluting indoor air in residences are emitted from furniture and finishing material. In Korea, most residences use Ondol heating system, and wooden floor has been widely used as Ondol floor material. Therefore, a considerable amount of pollutants are emitted from indoor furniture. In this study, the emission characteristics of VOCs (Volatile Organic Compounds) from the Ondol floor and fixed furniture were assessed by the experiment. Dividing oil, paint, and adhesive used in floor and furniture into natural and general material, specimens were constructed and small chamber method was used. Moreover, the floor and furniture in experimental residences were constructed with commonly used materials, and the measurement and the analysis of experimental data were done for 40 days for the floor and 110 days for furniture. In case of the floor, emission of most pollutants was significantly reduced and maintained a steady-state after 15 days. In the case of the furniture, toluene was continuously emitted and became steady-state after 60 days. The emission rate of the other substances remained unchanged. |
