Abstract

This study was conducted to determine the contents of heavy metals in leaves of roadside trees according to different growth stages in Daegu city. The orders of heavy metal contents in leaves of roadside tree and soil were Fe>Mn>Zn>Pb>Cu>Cr>Cd and Fe>Mn>Zn>Cu>Pb>Cr>Cd, respectively. The contents of heavy metals in leaves of roadside trees and soil showed an increasing tendency as the levels of traffic volume increased. The contents of heavy metals in loaves on October were higher than those on May. Zelkova serrate and Ginkgo biloba showed high contents of Cr, Cd and Pb.
