Abstract
The plant growing on pollution area could represent a specific flora having potential hyperaccumulators, accumulators and excluder species. This study examines lead (Pb) and cadmium (Cd) contamination in two parks soils, leaves, and one-year branch trees in Alborz, Iran, and its potential phytoremediation. In this research, Ailanthus altissima and Cercis siliquastrum were selected among the species planted in the city of Karaj and investigated the absorption capacity of lead and cadmium by these species. 240 samples of leaf, branch, and soil prepared by Digest hal device for chemical analysis and extraction and the number of heavy metals in each sample was measured by ICP. The result indicated that the relationship between lead concentration in the soil and lead concentration in the stem of the Ailanthus (Ailanthus altissima) and the Judas tree (Cercis siliquastrum) in both regions was positive and significant.
