Phytoremediation Potential of Native Hyperaccumulator Plants Growing on Heavy Metal-Contaminated Soil of Khatunabad Copper Smelter and Refinery, Iran

The characterization of prospective plants is one the critical issues in efficiency and success phytoremediation process. Due to adaption tolerance different environmental stresses, native plant species have priority this method. This study examined fifty five species, namely Launaea acanthodes, Artemisia sp., Cousinia congesta, Peganum harmala, Stipa growing near a smelter refinery Iran identify potential for phytoextraction phytostabilization. Therefore, Pb, Ni, Mn, Mo, S, Cu concentrations sampled soils were analyzed. Three pollution indices, metal accumulation index (MAI), translocation factor (TF), bioconcentration (BCF) used evaluating roots shoots each species. results indicated that with values 3.21, 1.09, 1.14 MAI, BCF, TF, respectively, appropriate area. Plants such as acanthodes congesta high BCF low TF showed Investigating indices elements demonstrated had value greater than 1 less 1; therefore, could be arsenic through phytostabilization technique. Furthermore, copper has very bioavailability these In addition, highly capable accumulating sulfur from soil because all inspected higher relevant was about 10. proposed applied practical applications remediation contaminated sites around factories mines southeastern Iran.
