摘要

Abstract

[Objectives] T his study aimed to illuminate the influence of different pollution levels and leaf locations on the accumulation ability of particulate matter (PM ) of C .camp hora trees ,and to provide scientific support for air-purif-ying plants selection .[M ethods]C .camp hora was selected as research materials ,and samples were collected from three different geographic sites w here plants suffered from different pollution levels and three different places of each leaf sample.T he number of particulate matter at different sizes were calculated and the micro-structure of plant leaves were observed with the Scanning Electron M icroscope (SEM ) and Image J software .[Results ] A significant difference in term of the PM numbers on the different leaf locations and different pollution areas was observed .PM number on the base vein of adaxial surface was significantly higher than those on both the apex of adaxial surface and w hole abaxial surface .T he particles of PM 2.5 was the major size of the adsorbed PM w hich were mainly gathered around cells and veins of C .camp horaleaves .T he amount of PM w hich were mainly concentrated around the stomaon the abaxial leave surface was increased with the increase of pollution levels .[Conclusion] Pollution level and leaf location can significant-ly influence the PM adsorption ability and PM were mainly adsorbed at the upper surface .
