| Abstract |
The effect of reducing the concentration of air contaminants by three species of plants was studied in afull-scale mock-up model. Aglaonema brevispathum, Pachira aquatica and Ficus benjamiana were used. Their positionsand amount were controlled. Field measurements were performed in models where the plants were placed and werenot. The dimensions of the two models were equal. The concentration of BTEX (Benzene, Toluene, Ethylbenzene,Xylene) and Formaldehyde were monitored, since they were known as most toxic materials. The concentration ofVOCs was monitored three hours after the plants were placed and three days after the plants were placed. The effectof reducing the concentration of air contaminants increased when the amount of plants increased, and when the plantswere placed in sunny area. The concentration of Toluene was reduced by 75.6% when 10 percent of the model spacewas occupied by Aglaonema. |
