摘要： We selected 6 species of landscape plants growing under different pollution levels and performed quantitative determination of PM2.5 adsorption. We compared the measured adsorption to the leaf morphology and the water-soluble ion content. The results indicated that the pollution level and plant leaf surface PM2.5 adsorption capacity were positively correlated. There was variation in the leaf area PM2.5 adsorption capacity for plants in different locations, allowing us to determine species-specific effects and effects of different pollution levels. The results of the study have important significance to design strategies to reduce urban air particulate matter pollution and improve air quality.
