Abstarct: The idea of using mextal-accumulating plants to remove heavy mextals and other compounds was first introduced in 1983.. Heavy mextals are primarily a concern because they cannot be destroyed by degradation. There are a variety of industrial processes that involve the use of lead such as mining, smelting, manufacture of pesticides and fertilizers and the burning of fossil fuels that contain a lead additive. Lead has been listed as a potential carcinogen in the U.S. Environmental Protection Agency Toxic Release Inventory is the most harmful mextal at the second place. Phytoremediation is the use of green plants to clean-up contaminated hazardous waste sites. In a greenhouse experiment, the effect of arbuscular mycorrhizal fungi (Glomus mossea) and EDTA chelate on the remediation of lead from contaminated soil was investigated in maize (Zea mays L.) and sorghum. The experiment was conducted as factorial baxsed on randomized complete block design with three replicates in the greenhouse of Shahrood University . Factors included three pb concentrations (0, 200 and 400 mg kg-1 soil), inoculation in two levels: with and without AM fungi(Glmous mosseae) and three EDTA concentrations (0, 5 and 10 mmol kg-1 soil). The results showed that pb stress significantly reduced dry biomass of root, stem , leaf and phosphorus content of maize and sorghum, also significantly reduced height, chlorophyll index and fungal colonization in maize which most effective level of pb was 400 mg kg-1 soil. Due to the increased solubility and rapid absorption of lead, the aplication of EDTA chelate, especially at the level of 10 mmol kg-1 soil, significantly reduced dry biomass of root, leaf and chlorophyll index of maize and had only negative effect on dry biomass of root in sorghum. The Mycorrhiza fungi significantly enhanced phosphorus uptake in root and shoot of maize and sorghum and also increased pb uptake in levels of 200 mg lead kg- 1 soil. On the other hand, plants in the levels of 200 and 400 mg lead kg-1 soil combined with chelate, containing higher concentrations and amounts of lead. Also, the aplication of EDTA chelate, especially at the level of 10 mmol kg-1 soil, cause increased bioaccumulation coefficient and The remediation factor In both plant and Translocation factor in maize. Rate of lead in the stem of mycorrhizal sorghum plants were mostly higher than those of non-mycorrhizal plants, particularly in 5 mmol chelate in kg-1 soil .Maximum lead in parts of both plants were observed respectively in root, leaf and stem. Since the lead content index more effective than concentration of the mextal in the phytoremediation, As reduce the environmental risks, it is recommended that application of lower concentration of celate in mycorrhizal plants.
