We evaluated Ambrosia artemisiifolia var. elatior, Ambrosia trifida, Rumex crispus which were reported to have good phytoremediatibility in different concentrations of Cu and Cd. Different growth responses were found in different heavy metal concentrations. Good growth rate for A. trifida and A. artemisiifolia var. elatior in Cu and Cd treatments and poor growth for R. crispus in Cd treatment were found. Although growth was retared in all tested weeds up to 200ppm for Cu and 50ppm for Cd, the high amount of heavy metal uptake indicated that these weeds could be used as phytoremediation. The choice of proper plant for bioremediation in different sources of heavy metal pollution seems important. In this regard, A. trifida which showed little variation in Cu accumulation in shoot under different Cu concentrations could be used for phytoremediation and phytostabilization.
