چکیده	Phytoremediation is considered as a clean, cost-effective and non-environmentally disruptive technology. In order to study of lead phytoremediation, 1 year old seedlings of Salix aegyptiaca and Eleagnus angustifolia were used. Various concentrations of Pb were sprayed on seedlings three times with 10 days interval in June 2009. The Pb accumulation in different organs of seedlings was measured by atomic absorption method at the middle of August and at the end of October. Considering accumulation of Pb, there was a significant difference between S.aegyptiaca and E.angustifolia. Although both of species were able to transferring lead from leaves to stem, however the results showed that Russian olive acted better than Egyptian willow in treatments with concentrations less than 4000ppm. Lead accumulation in unit dry weight of Russian olive in most treatments was more than willow; while considering more biomass of Egyptian willow; the results showed that lead accumulation in the seedlings of willow was significantly more than Russian olive.
