The study of heavy metals in water and sediment was
carried out in the upper reach of the New Calabar River, Niger Delta region in
Nigeria. Three sampling stations were selected which were
Choba, Ogbogoro and Aluu.
Water and sediment samples were collected and analysed, using the buck
scientific Atomic Absorption/Emission spectrometer
200 A model. Water Physico-chemical parameters were measured in situ. Dissolved Oxygen had an overall mean of 4.17 ¡À 0.83 mg/l, temperature
had mean value of 28.34¡æ ¡À 1.07¡æ, pH had a mean value of 5.52 ¡À 0.54,
electrical conductivity had a mean value of 1123.39 ¡À 859.58 ¦Ìs/cm, BOD had mean value of 4.45 ¡À 1.14 mg/l, salinity had a mean value of 1.47 ¡À 1.15 ppt while TDS had mean value of 598.13 ¡À 529.58 mg/l. Result of heavy metals in water indicated that
Zn had an overall mean value of 1.77 ¡À 0.53 ppm, Cr
had mean value of 0.65 ¡À 0.21 ppm, Pb
had a mean value of 0.19 ¡À 0.11
while Fe had an overall mean value of 1.52 ¡À 0.34 ppm.
Heavy metals in sediment indicate higher concentration than in Water: Zn had an
overall mean value of 7.90 ¡À 2.59 ppm, Cr
observed an overall mean value of 1.94 ¡À 0.81 ppm, Pb
had an overall mean value of 2.23 ¡À 0.61 ppm,
while Fe observed an overall mean value of 87.43
¡À 6.57 ppm.
The result indicated that the source of heavy metals in the aquatic environment
could be industrial effluent, domestic waste, dumping of scrap, vessel in the water
way and runoff from agricultural land.
