Phytoremediation Prospects of Heavy Metals by Indigenous Plants Growing in Industrially Polluted Soils

39 indigenous plant species in 18 families were collected and investigated in four heavy-metal polluted sites. The tolerance and hyptoextraction characteristics of them to Cd, Pb, Cu, Zn and As were examined. In field survey, Bidens bipinnata, Artemisia dubia, Polygonum lapatuifolium, Chenopodium ambrosioides and Solanum nigrum showed to concentrate remarkable heavy metal in shoots. In the further pot experiment, phyptoextraction characteristic of 9 potential plant species in Pb, Zn, Cu, Cd and As was examined, and the accumulation potential of these plants was affirmed. The result also suggested that the community had much more ability to extract Cd, Pb, Cu, Zn and As, and grew better than individual compared with pot experiment. These findings were of interest pertaining to the removal processes for treating endemic plant communities with heavy metals.
