Relationship between adsorption capacity of PM2.5 and leaf surface characteristics of AFM for typical greening trees in the Western mountains of Beijing

Abstract

Six greening tree species (Pinus bungeana, Pinus tabulaeformis, Salix babylonica, Acermono, Ginkgo biloba, Populus spp.) from the Western mountains of Beijing were selected as research materials. The PM2.5 adsorption capacity of their leaves was measured in summer and autumn through the use of an aerosol generator. The surface micro⁃morphological
