MA Yue liang,JIA Gui mei,WANG Yun peng,LIU Hui ping (Guangzhou Institute of Geochemistry, Chinese Academy of Sciences, Guangzhou 510640,China)  
In this paper, the contents of heavy metals in leaves of plants in Guangzhou region were measured, and index of air environment pollution of plants was studied with a discussion of the relationship between the contents of heavy metal elements of leaves and air environment pollution. The results indicated that plants are seriously polluted by Cu,Pb,Cd,Cr and the contents of heavy metal elements in heavy pollution area are higher than that in clean control place, the index of air pollution of plants can be used for evaluating air quality and classification assessment of air quality. Therefore, it has been proved that this method is a good way in evaluating air pollution using contents of heavy metals in leaves of plants.
