A Study on the Filtering Impact of Plants and Soil on the Reduction of Volatile Organic Compounds

摘要

The research regarding the importance of indoor air quality is recently becoming issue from Korea and various methods are being used to improve interior air quality. Indoor air contamination became an important issue as the amount of infiltration is diminished by tightly sealed envelopes, and the building materials made of chemical components are frequently used. As the interest in plants improving indoor air quality is becoming higher like the study performed by NASA in 1980s, the study on the effect of plants or soil on the reduction of air pollutants is being performed plentifully. This study aims at examining the impact of soil and plants, on the improvement of air purification. Experiments were performed in a mock-up system where the effect of concentration reduction in Volatile Organic Compounds can be monitored. The variations of concentration of Toluene, Etylbenzene, Xylene, Stylene and Formaldehyde were monitored. This study explored the reduction effect of indoor pollutants by the kinds of plant(Aglaonema brevispathum, Pachira aquatica) and Soi(Hydro-ball, Neo-coal, Charcoal).In the result, the reduction effect of Toluene, Xylene and Ethylbenzene was to be sensed effectively, and the effect of plants and soil wasproven. When Aglaonema was placed, the reduction effect of air pollutants was significant.Also the effect of Charcoal and Hydro-ball was great.
