Abstract	Contamination of heavy metals from mining causes major environmental problems all over the world, representing threats to soil resources as well as human health. Phytoremediation can be potentially used to remediate metal-contaminated areas. This study aims to assess the extent of metal accumulation by plants found in two mine tailings area in Aletai in the northwest part of China. In present study, shoots and roots of the 19 plant species and the associated soil samples were collected. The concentrations of elements (Pb, Cu, Zn and Cd) of collected samples were then analyzed using flame atomic absorption spectrometry. The results showed that the concentrations of Pb, Cu, Zn and Cd in total mine tailings soil varied from 311 to 1162, 74 to 3251, 1618 to 4815, and 3.37 to 34 mg/kg, those in the plants ranged from 7.35 to 512, 20.4 to 873, 18.7 to 1279, and 0.37 to 47.6 mg/kg, respectively. Although no plant species were identified as metal hyperaccumulators, among those plant species collected from the two mine tailings, Spiraea media Schmidt was most suitable for phytostabilization of Cu (BCF = 6.77). Polygonum aviculare has the potential as a hyperaccumulator, especially in phytoextraction for Cu. Karelinia caspica (Pall.) Less was most effective species for phytostabilization of Cd. These results suggested that some native plants growing on mine tailings area may have the potential for phytoremediation.
