Phytoremediation Potential in Platanus orientalis, and Fraxinus rotundifolia (Case study: 22 Bahman Park, Karaj)

This study was conducted to determine the absorbance ability of Cadmium (Cd) and lead (Pb) by the leaves and shoots of Platanus orientalis and Fraxinus rotundifolia in Karaj, Iran. In the selected site, 20 samples from one-year-old leaves and shoots as well as 20 soil samples were gathered and analyzed by ICP. The results indicated that no significant difference in absorbed contents of Cd and Pb in the leaves among the trees. However, accumulation of Cd in shoots of Fraxinus rotundifolia was significantly higher than Platanus orientalis. Also accumulation of Pb in shoots of Platanus orientalis was significantly higher than Fraxinus rotundifolia (p<0.05). The amount of Pb in the soil of the study area was significantly higher than Cd.
