  This study was carried out to investigate the ability of water hyacinth (Eichhornia crassipes (Mart.) Solms.) to absorb and translocate iron (Fe) and copper (Cu). The study was conducted with three concentration gradients of Fe and Cu at 10, 15, 20 mg L-1 and control (no metal). The whole set-up was carried out in triplicate and the experiment lasted for 12 weeks. The results showed that iron (Fe) had the highest accumulation value in the root (11.22±6.69 mg kg-1), while copper (Cu) had the highest value in the leaf (3.80±0.12 mg kg-1) both occurred at treatment spiked at 20 mg metal/L of water. Statistical analysis showed that there was significant difference (p<0.05) in metal accumulation among treatments. The Translocation Factor (TF) values for Fe ranged from 0.49±0.57 to 0.68±0.27 in leaf and 0.64±0.17 to 0.77±0.18 in the stem while the TF values for Cu ranged from 0.78±0.08 to 1.12±0.12 in leaf and 0.72±0.32 to 1.09±0.19 in the stem. This reveals that Cu had better translocation capability than Fe. Highest values of Bioconcentration factor (BCF) for Fe and Cu were 2.32±0.65 at 20 mg L-1 and 0.72±0.01 at 15 mg L-1 obtained in the root and leaf respectively, indicating that the accumulation potential of Fe by water hyacinth is higher than Cu. So, according to the accumulation capabilities of the investigated plant (Eichhornia crassipes), this study showed that the plant was found to be a promising candidate for phytoremediation and adequate for bio-monitoring programmes for contaminated water.
