The comparatively pollution-free parks far from the traffic environment were used as a control. Findings: The nearer the sampling location is to the traffic environment, the higher is the absorption of Pb, Cd, and S; the higher, the electric conductivity; and the lower the pH value in the leaves and bark of urban trees.
