Abstract:
Thirteen plant species from Euphorbiaceae，Moraceae and Araliaceae families were tested for their abilities of removing formaldehyde (FDH) in the air.Each plant was placed for seven days in a 1.0 m×1.0 m×0.8 m glass box filled with formaldehyde with the initial concentration of 15 mg/m3，determination of chlorophyll content，cell membrane permeability，dry matter，formaldehyde content,purification of formaldehyde-polluted air by several potted plants were studied.The results showed the top resistance of Polyscias balfouriana to formaldehyde pollution damage；some plants such as Hedera nepalensis,Schefflera octophylla showed the secondary resistance ability to FDH；other plants such as Polyscias fruticosa, Ficus microcarpa, Euphorbia pulcherrima showed the three levels resistance ability；plants such as Pedilanthus tithymaloides, Euphorbia neriifolia var.cristata，Codiaeum variegatum，Ficus benjamina showed the four levels resistance ability.Ficus elastica and Polyscias balfouriana showed no resistance to FDH.The absorption of plants for FDH in the glass chamber was found especially apparent different during the first three days.In conclusion，5 species of the potted plants which could be recommendable to be used for FDH purification were Hedera nepalensis, Schefflera octophylla，Euphorbia pulcherrima，Ficus benjamina,?Polyscias guifoylei.These plants had a high absorption ability to FDH and had less damage.
