The present study tested the remediation potential of Eichhornia crassipes (water hyacinth), for the removal of chromium (Cr) and Zinc (Zn) and Nickel (Ni). Fresh and young plants of equal size were grown in hydroponic medium and supplemented with 300, 600, 1200 and 2400µg/L of Cr and 600, 1200, 2400 and 6000 µg/L of Zn and 300, 600, 1200 and 2400 µg/L of Ni individually for 15 days. The bioaccumulation pattern was reported high in Zn culture. Metal toxicity in the floating macrophyte showed a significant reduction (P <0.001) on phytomass, chlorophyll, NO₃-N and PO₄-P uptake inhibition in comparison to control. The rate and amount of Cr uptake were minimum as compared to Zn and Ni. The rate of uptake increased with concentration and decreased with increasing time duration. The uptake and accumulation of Cr in the root were always higher than that of shoot except between 2 h to 72 h period at an initial concentration of test metal. The lowest and the highest tolerance indices in Eichhornia crassipes were recorded for Cr and Zn respectively.  Bioconcentration factor (BCF) for Zn, Ni, and Cr were 14.6, 12.5 and 10.2 respectively, indicates that Eichorrnia crassipes can be a moderate accumulator of heavy metals and the ubiquitous weed could be used to clean aquatic bodies threatened with pollutants.
