Removal of PM2.5 via atmospheric humidity caused by plant transpiration




2018.07.06 23:02

 Particulate matter (PM) reduction has emerged as one of the most significant challenges in public health and environment protection worldwide. To address PM-related problems and effectively remove fine particulate matter (PM2.5), environmentalists proposed tree planting and afforestation as eco-friendly strategies. Scindapsus yielded a high PM removal efficiency for smoke type PM2.5 under active transpiration. The correlation of PM removal and relative humidity (RH) and evaluated the increased effect of RH on PM2.5 removal by using a plant-inspired in vitro model. Based on the present results, the increase of RH due to leaf transpiration is crucial to the reduction of PM2.5 using plants.
