Purification of Indoor Air Formaldehyde by Plants:a Review / 环境与健康杂志

The pollution hazard of formaldehyde in low level from indoor air is worldwide.Many researches have been focused on the ornamental plant purification for indoor air formaldehyde in low concentration.Although a numbers of literatures have documented that gaseous formaldehyde can be removed by many plant species,a long term purification efficiency of the plants for formaldehyde is uncertain.The research in the future works should be focused on phytotoxieity of formaldehyde,a long term purification efficiency of plants,soil contribution to formaldehyde removal under plant-soil system,effects of complex pollutants on the purification of plants for formaldehyde,and volatile organic compounds from the plants which can remove formaldehyde.
