Background
Many areas of land in different regions contaminated by heavy metals that pollution from human activities, industrial wastewater and sewage sludge waste water consumption are derived. Among the pollutants, heavy metals, especially lead, cadmium and mercury due to serious environmental consequences and profound effects on human health are of special importance. Phytoremediation, a new technology to remove contaminants from the environment. This technology compared to other methods of refining, low cost and simple.Material and
Methods
The aim of this study was to evaluate the feasibility of remediation of soils contaminated with lead, cadmium and mercury by plants. For this purpose, preparation, preparation and consolidation of contaminated soils at different concentrations and the seed of the crops of Lolium, Amaranth and Sorghum were performed.Results
The results showed that the maximum and minimum concentrations, respectively, were related to the soil surrounding industrial areas forest. According to the findings in alkaline soils metals uptake by plant roots was higher than the shoots. The results showed that concentration does not have a significant effect on uptake. The Chelated increase the availability and uptake of heavy metals in plants.Conclusion Comparison of the efficacy of treatments with and control, it was concluded that plants can effectively reduce the concentration of heavy metals from contaminated soils.
