An assessment of some Heavy Metals in Sediment of Otamiri River, Imo
State, South-Eastern Nigeria was conducted between the months of August to
October, 2015. Water samples were collected from four sampling stations
established along the river channel for 3 months (fortnightly). Physic- chemical
parameters were analyzed following conventional field and standard laboratory
techniques. Temperature range between 24.25℃ - 30.50℃, Hydrogen ion mean
concentration value of 7.01 ± 0.19 ppm was obtained, CO2 recorded a
mean value of 3.41 ± 0.19 ppm, Total Hardness recorded a mean value of 35.59 ± 1.09
ppm, Ammonia recorded a mean value of 1.36 ± 0.11 ppm, Dissolved Oxygen
recorded a mean value of 4.61 ± 0.26 ppm, and mean value of 4.63 ± 0.12 ppm was
observed in Biochemical Oxygen Demand. Nickel concentration ranged between 2.16
- 4.21 ppm, Lead range 0.71 - 6.01 ppm, Chromium range between 1.63 - 11.067,
Chromium range between 0.74 - 3.61, and Copper concentration range between 0.94
- 10.36. All the parameters measured were significantly different at p < 0.05
except pH, Nitrate, and Nickel throughout the sampling period.
