Abstract

Evaluation of Ambrosia artemisiifolia var. elatior, Ambrosia trifida, Rumex crispus for phytoremediation of Cu and Cd contaminated soil.

Abstract

Ambrosia artemisiifolia var. elatior, Ambrosia trifida and Rumex crispus, which were reported to have good phytoremediation qualities in different concentrations of Cu and Cd, were evaluated for growth responses 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 retarded in all tested weeds up to 200 p.p.m. for Cu and 50 p.p.m. for Cd, the high amount of heavy metal uptake indicated that these weeds could be used for 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 shoots under different Cu concentrations, could be used for phytoremediation and phytostabilization.
