The elements of Zn, Si, Rb, Pb, Ni, Mg, Fe and Ba with a transfer factor have more than 1 have ability to transfer from root to stem and accumulate in the aerial parts of Astragalus sp. The highest and lowest transfer factors were respectively Si (2.11 mg / kg) and Al (0.38 mg / kg) respectively. Also, there is a strong correlation coefficient (P value <0.01) - more than 50% - between metals with each other. The present study showed that Astragalus sp. Can accumulate a wide range of concentrations of metals in the soil. It has the ability to absorb Zn, Si, Rb, Pb, Ni, Mg, Fe and Ba in the airial parts. Elements of Al, As, Mn, Cu, Sr, Cr and Mo showed more accumulation in the root than the aerial parts This indicates the potential of this plant in phytoremidation and phytostabilization in the contaminated areas.]]>
