Assessment of Cr+6 Accumulation and Phytoremediation Potential of Three Aquatic Macrophytes of Meghalaya; India

Donboklang Marbaniang, S.S. Chaturvedi

A laboratory experiment was conducted to examine Cr+6 uptake capacities of three aquatic macrophytes (Scripus mucronatus; Rotala rotundifolia and Myriophyllum intermedium). The selected macrophytes were transferred to the laboratory containing nutrient solution enriched with 1.0; 2.0; 4.0; 8.0 and 16 mg L-1 of Cr+6 and were separately harvested after 2; 4; 6; 8 and 10 days. The bioaccumulation study showed a linear relationship for S. mucronatus; R. rotundifolia and M. intermedium plant parts with the exposure time (210 d). Cr+6 concentrations were found to be higher in the root than the shoot in S. mucronatus but reverse in the case of R. rotundifolia and M. intermedium. The maximum bioconcentration factor (BCF) and translocation factor (TF) value were calculated as 1034 and 0.68 for S. mucronatus; 444 and 2.36 for R. rotundifolia and 1048 and 3.37 in M. intermedium respectively. The experimental results demonstrated that the S. mucronatus and M. intermedium can be used for removal of Cr+6 from Cr+6 -contaminated water
