近日,网上出现一种说法:室内养一些植物,可以有效消除室内空气的PM2.5。对此,南京林业大学森林培育系田野教授认为,任何植物对氮、硫氧化物都有一定的吸收能力,而且叶片会有一定的滞尘作用,可以适当减轻PM2.5的危害。但这个效果都是基于植物数量来说的,一个房间的PM2.5是不可能通过几盆植物就能够改善的。中科院大气物理研究所研究员白建辉解释得更清楚:植物可以吸附PM2.5,主要是大气中的颗粒物
Recently, there is a saying on the Internet that some plants can be kept in the house to effectively eliminate PM2.5 from indoor air. In this regard, Nanjing Forestry University Department of Forest Cultivation Professor Tian believes that any plant has a certain absorption capacity of nitrogen and sulfur oxides, and the leaves will have some of the role of dust, you can properly reduce the hazards of PM2.5. But this effect is based on the number of plants, a room of PM2.5 can not be improved by a few pots of plants. Institute of Atmospheric Physics researcher Bai Jianhui explained more clearly: plants can adsorb PM2.5, mainly in the atmosphere of particulate matter
