Uptake and Accumulation of Cd from wastewater by Alternanthera philoxeroides (Mart.) Griseb

Nimisha, Abhik Gupta

Abstract :

The study investigates the potential of the wetland macrophyte Alternanthera philoxeroides (Martius)  Griseb (Amaranthaceae) in uptake and accumulation of cadmium (Cd). A. philoxeroides was exposed in  the laboratory to 3.0, 5.0, and 10.0 mg L–1 Cd, and Cd accumulation was estimated at the time intervals of 3, 24, 72,  240 and 720 hours. The accumulation of Cd as well as the bioaccumulation (BCF) and translocation factors (TF) were  the highest in stem, followed by that in root, and the lowest in leaf. The large biomass of the stem of A. philoxeroides  coupled with its high Cd concentration as well as BCF and TF values, are indicative of its potential use in Cd phytoremediation.
