Abstract

【Purposes】Beijing, as an international metropolis, has a serious environmental problem. Seasonal difference of PM2.5 adsorption and its affecting factors between broadleaf trees was observed. It aims to investigate the adsorption mechanism of leaf on PM2.5 among various tree species and support the selection of urban landscaping tree species.【Methods】 Four tree species(Salix babylonica, Acer mono, Ginkgo biloba and Populus spp.)were selected and their accumulation capacity of PM2.5 were observed in Western Mountainous areas of Beijing. An aerosol generator was used for quantitative determination of PM2.5 adsorption. We measured contact angel between leaves and water, diiodomethane. Surface free energy and its polar and dispersive component of leaf were calculated based on Owens-Wendt-Kaelble method and Young equation.【Results】The accumulation capacities of leaves on PM2.5 per leaf area were S. babylonica((0.97±0.46)μg/cm2)>A. mono((0.78±0.39)μg/cm2)>G. biloba((0.69±0.31)μg/cm2)>Populus spp.((0.62±0.21)μg/cm2).The differences of adsorption capacity on PM2.5 between S. babylonica and G. biloba, Populus spp. were obvious(α=0.05, P<0.05).The adsorption quantity of tree on PM2.5 in autumn was higher than that in summer. There was a significant relationship between leaf surface wettability(leaf contact angel)and leaf adsorption quantity on PM2.5(P<0.01).The adsorption of tree on PM2.5 was positively correlated with leaf surface free energy(P<0.05). Its dispersive component had a significant correlation with leaf adsorption quantity on PM2.5(P<0.01), where as non significant relationship was found with polar free energy. 【Conclusion】 PM2.5 accumulation capacity among the broadleaf trees: the strongest was S. babylonica and the weakest was Populus spp. Accumulation capacity of them in summer was higher than it in autumn. We can make the plans on city landscape rationally, according to PM2.5 adsorption characteristics of various tree species, so as to develop the ecological function of urban greenland system.
