홈페이지논문 초록 (Abstract)
Particulate matter pollution is an environmental problem that has received significant attention in modern society. Environmentalists have proposed the use of indoor air purification plants as a green strategy to effectively remove fine particulate matter (PM2.5) in air. Among various air purification plants, mosses have been used as biomonitors for heavy metals and air pollutants. However, their PM removal effect under different conditions and their primary mechanism are still unclear. Herein, we investigated the PM removal performance of Racomitrium canescens in a sealed chamber under flow and relative humidity conditions. Under the flow condition, the chamber with Racomitrium canescens demonstrated 22% and 30% greater PM2.5 removal efficiencies for aerosol and solid particles, respectively, than that without Racomitrium canescens. Under the relative humidity condition, the chamber with wet Racomitrium canescens demonstrated 8% and 11% greater PM2.5 removal efficiencies for aerosol and solid particles, respectively, than that with dry Racomitrium canescens. The increase in the effective surface area owing to the microscale protrusive surface structure of Racomitrium canescens is an important factor in PM deposition.
