This article presents the experimental study results on the gaseous toluene absorbability of the ten native plant species of Vietnam. The selected species for this research are all aesthetic and can be planted in the room as ornamental plants, including: Dracaena fragrans, Schefflera heptaphylla (L) Frodin, Dryopteris parasitica, Costus speciosus Sm., Strobilanthes aliinis (Griff.) Y.G. Tang), lindsaea javanensis Bl., Dieffenbachia sp., Rhapis excelsa (Thunb.) Henrry ex Rehd., Curculigo capitulata (Lour.) Kuntze., and Nageia fleuryi (Hickel) de Laub. The study was conducted within airtight glass chambers with a dimension of 60 em x 60 cm x 100 cm. In each research chamber, there is one blower used to equally stir air, and one hygrometer, one thermometer, and one light meter used to monitor the microclimate factors dUring the experiments. The study results show that, when these plants exposure to the gaseous toluene at the concentration of from 8 mg/m3 to 12 mg/m3, after 72 hours of exposal, from 0.20 - 2.70 ug/cm2 (leaf area unit) of gaseous toluene were removed by these plants. Three species that are best at removing toluene during the experiments are Dracaena fragrans, Schefflera heptaphylla (L) Frodin, and Curculigo capitulata (Lour.) Kuntze.
