Abstract

Tolerance and uptake of heavy metals by plants, differs from one to another species. A plant can be used for decontamination of contaminated soil and waters if it can resist and reduce heavy metals from contaminated resources. The objective of this research was to investigate the capability of halophyte Chenopodium Album L. to phytoextract lead and to determine the clean-up time from contaminated soils. For this purpose, a completely randomized design with six treatments of 0, 150, 300, 600, 900 and 1200 mg Pb/kg soil and four replicates was established. After full development of plants, they were harvested and their lead in roots and shoots were measured. The results indicated a nonlinear positive relationship between the lead concentrations in soil and that accumulated in both roots and shoots. The highest extracted lead which was accumulated in roots and shoots were 64.75 and 4.12 mg/kg, respectively. The highest dry matter of 35 ton/ha produced in one year belonged to 600 mg Pb/kg soil treatment. The minimum clean-up time was nine years in the treatment of 600 mg Pb/kg soil that appeared at the 5% contamination. Since Chenopodium Album L. can be cultivated three times a year, and due to its high biomass and capability of lead accumulation, this plant might be used as a hyper-accumulator to remediate lead from Pb-contaminated soils.
