Abstract

Background and Objectives: The use of medicinal plants for remediation of heavy metals from contaminated soils is an economical, cheap and effective strategy. The widespread transfer of natural materials and pollutants to different parts of the environment (soil, water and atmosphere) has imposed great pressure on the self-purification ability of the soil. Accumulation of pollutants is a concern regarding both humans and ecosystems. Among pollutants, heavy metals are particularly important because they are not degradable and also have harmful physiological effects on organisms even at low concentrations. Soil pollution with heavy metals in human societies is one of the major environmental problems and the transfer of these elements via crop production affecting human population health. One of the modern and low cost methods for remediation of contaminated soils is the use of plants. Phytoremediation is an emerging technology which utilizes plants and microorganisms in the rhizosphere to delete, modify or limit the toxic chemicals in soil, sediment, groundwater, surface water and even atmosphere. The aim of this study was to evaluate the Phytoremediation ability of Thymus daenensis Celak. with Mycorrhizal fungi in polluted soils with Lead and Cadmium. Materials and Methods: This study was conducted as a factorial exam in the greenhouse conditions. The first factor was four levels of heavy metals: Lead (100 mg. kg-1 soil), Cadmium (15 mg. Kg-1 soil), concurrent use of Lead and Cadmium and control (zero) and the second factor was fungal treatments (at five levels: G. intraradices, G. Mosseae, G. fasciculatum, the simultaneous use of all three species and control-non inoculated) in a randomized complete block design in three replications. Results: Analysis of variance showed a significant effect of Mycorrhizal fungi on Pb and Cd concentration in shoots and roots of thymus. The highest Cadmium concentration in polluted soil was observed in Shoot (62. 1 mg. Kg-1 DW) inoculated with G. mosseae and root (56. 1 mg. kg-1 dry weight) inoculated with G. fassiculatum respectively. Conclusion: The results showed a high ability of Thymus daenensis Celak. to absorb heavy metals from contaminated soils. Other findings of this study were more accumulation of Lead in root than shoot of Thymus daenensis. Based on the results, Mycorrhizal fungi can improve the Phytoremediation of contaminated soils with Cd and Pb.
