室内苯污染的植物生态修复技术研究进展

苯是室内化学污染的主要污染物,具强致癌和致畸形能力,是室内空气污染的三大隐形杀手之一,严重威胁着人们的生命安全和健康.室内植物不仅对室内苯污染物具有很强的净化修复能力,而且具有重要的吸碳放氧功能,尤其具有安全、稳定、持续的净化效果.因此,室内植物生态修复技术已成为治理室内苯污染的重要手段.文章阐述了室内苯污染的概况和植物生态修复技术的内涵;从植物净化修复苯污染的机理机制、植物对苯污染的吸收净化能力和耐受能力三方面综述了室内苯污染的植物生态修复技术研究进展;指出了目前研究存在的不足;展望了室内苯污染的植物生态修复技术的应用和发展前景.

Research progress of ecological plant rehabilitation technology of indoor benzene pollution

Benzene is the main chemical pollutant of indoor air pollution,has strong capability of carcinogenesis and malformation,and has been known as one of the three invisible killers of indoor pollution,which is severely threatening human life and health.Indoor plants not only have strong air repair ability,but also have the function of absorbing carbon dioxide and releasing oxygen,especially with safety,stability,continuous purification effect,so the indoor plants ecological restoration technology has become the important means to treat indoor benzene pollution.The paper expounds an overview of indoor benzene pollution and the connotation of plant ecological rehabilitation technology,reviews the research progress on ecological plant rehabilitation technology of indoor benzene pollution from three aspects：the purification mechanism of restoration,the ability of plants to absorb benzene and the resistance,points out the shortcomings existing in the present research,and makes a prospect for the application and development of the ecological plant rehabilitation technology of indoor benzene pollution.
