A Study on Improvement of Indoor Air Setting by Korean Native Plants

This study conducted the experiment of concentration reduction effect if indoor air pollutants to Korean native plants, Fatsia japonica Decne. et Planch. and Ardisia pusilla DC. The two plants are advantageous in that they are highly available as they grow wild, and being easy to get. Fatsia japonica Decne. et Planch. is a plant of its wide and large leaf diverged 7 or 8 parts, which is thought to have a high effect of air purification. Ardisia pusilla DC. has a smaller leaf than Fatsia japonica Decne. et Planch., which is characterized by more leaves and beautiful. Field measurements were performed in models where the plants were placed and were not. The dimensions of the two models were equal. The concentration of Benzene, Toluene, Ethlybezene, Xylene, Formaldehyde were monitored, since they were known as most toxic materials. The concentration of VOCs was monitored three hours after the plants were placed and three days after the plants were placed. As a result, they had all an effect of reducing pollution. Especially, Fatsia japonica Decne. et Planch. was more excellent in reducing Toluene and Formaldehyde with a lot of pollutants.
