Project Description and Objectives
Fine particles (PM2.5) became the primary pollutant of the urban atmospheric environment in China, which leads to significant health risks to human beings. Leaves of plants with special surface structures and features could block, absorb and remove particles from the atmosphere. Therefore, the prevention of PM2.5 by vegetation is now seen as one of the most promising ways to alleviate urban air pollution. Presenting the research of the PM2.5 dry deposition process and influential factors, and developing an in-situ measurement of dry deposition velocity, will indeed record and show the benefit of air quality improvement by urban plants.
The objectives of the project are as follows. First, developing the observed PM2.5 dry deposition velocity（Vd’）as an in-situ measurement. Second, monitoring the intensity and characterizing the emission features of different PM2.5 polluted areas by a CMB model and quantifying microscopic characteristics of leaves such as physiological, physical and thermodynamic indicators. Third, perform a mixed effect model to discuss the impact of PM2.5 emission features and leaf surface characters on variation of Vd’ and address the key factors of plant characteristics on PM2.5 deposition. The results could provide scientific basis for the benefit of urban vegetation on improving pollution control and air quality, which is of great theoretical and social significance.
