- This study evaluated the level of some heavy metals in water, sediment and Eichhornia crassipes from Kolo creek, Niger Delta, Nigeria. Triplicate samples were collected from three locations. The samples were processed and analyzed following standard procedures. Results showed that the concentration of lead, cadmium, iron, manganese, mercury and copper ranged from 0.001 – 0.002 mg/l, 0.001 – 0.001 mg/l, 0.137 – 0.157 mg/l, 0.013 – 0.017 mg/l, 0.000 – 0.001 mg/l and 0.019 – 0.114 mg/l respectively for water, 1.676 – 1.757 mg/kg, 0.137 – 0.147 mg/kg, 3.020 – 3.810 mg/kg, 0.407 – 0.490 mg/kg, 0.011 – 0.023 mg/kg and 0.365 – 0.782 mg/kg respectively for sediment. Furthermore, the level of heavy metals in the Eichhornia crassipes ranged from 0.002 – 0.003 mg/kg, 0.003 – 0.004 mg/kg, 0.000 – 0.004 mg/kg and 0.040 – 0.048 mg/kg for lead, cadmium, mercury and copper respectively. Statistically, there was no significant variation (P>0.05) among the various locations in majority of the heavy metals analyzed. The heavy metal concentration in water was below the permissible limit for heavy metal in potable water as specified by World Health Organization and Standard Organization of Nigeria. The concentration of heavy metals were low in water and Eichhornia crassipes suggesting that Kolo creek is not contaminated by heavy metals. However, the heavy metal were in the order Eichhornia crassipes< water sample< sediment.
