In recent years, use of plants for remediation of contaminated soils, especially removal of heavy metals, is considered. The current study tends to investigate the removal of cadmium and lead ions by the Arundo donax L, the plants were grown under greenhouse conditions in pots containing soil for 21 days with different concentrations of cadmium and lead ions. Then concentration of them in soil and different organs of the plant was measured by atomic absorption spectrometry. The results showed that the effect of Cd was stronger on the growth of the roots, while the effect of Pb was stronger on the shoots. At the physiological level, Cd treatment was found to induce low levels of lipid peroxidation and membrane leakage with less affected photosynthesis in the leaves of the treated Arundo donax compared to the effects of Pb. The results presented here showed that a high amount of the total absorbed Cd (86.66%) was accumulated in roots, while a high amount of the total absorbed Pb (78.74) was tranlocated to shoots of Arundo donax L. The results show, Arundo donax L is suitable for cadmium and lead and this technique is in-situ method, simple, and low cost. [ABSTRACT FROM AUTHOR] |
