摘要：The greening trees can absorb heavy metal pollutants in the atmosphere. The researchers made a study of the cadmium (Cd) and chromium (Cr) content in the leaves of 17 kinds of greening trees in Xinxiang City.

Heavy mental content of different greening trees really differ from each other, which ranks as follows: Populous Alba
