The levels of physicochemical properties of Mini Whuo Stream in Port Harcourt, Rivers State, Nigeria was evaluated. The physicochemical parameters were analyzed using standard conventional procedures. The average values recorded for the physicochemical parameters during the months of investigation were in the range; temperature; 30.00±0.42-30.26±0.83oC, with all-round mean of 30.14±0.47oC, pH; 6.22±0.33-6.42±0.25 (6.29±0.29), electrical conductivity; 146.01±74.04-147.26±75.13µS/cm (146.58±74.69 µS/cm), total alkalinity; 61.63±6.37-62.20±6.41mg/L (61.91±6.41 mg/L), sulphates; 109.67±51.34-110.67±51.88mg/L (110.22±51.81 mg/L), nitrates; 12.20±2.38-12.60±2.86mg/L (12.31±2.65 mg/L), turbidity; 49.32±1.49-50.18±2.02 NTU(49.83±1.55 NTU), TDS; 74.20±36.43-75.61±37.50 mg/L (75.00±36.81 mg/L), TSS; 27.14±2.12-28.37±0.78mg/L (27.64±1.89 mg/L), chlorides; 15.17±2.90-15.66±2.70mg/L (15.34±2.65 mg/L) and salinity; 24.36±4.83-24.82±4.97mg/L (24.66±4.78 mg/L). The evaluation of the physicochemical parameters showed that the Mini Whuo Stream has been contaminated due to human activities within the stream and therefore adequate measures should be taken to forestall the present situation of the stream in order to mitigate any possible increase in deterioration of the studied physicochemical parameters in the stream beyond acceptable limit.

The study assessed the concentration of heavy metals in three oil spill sites in Emohua local government area in Rivers State, Nigeria. Soil samples were collected at depth 0-30cm for surface soil samples and up to 10m for sub-surface soil samples depending on the depth of borehole. Groundwater samples were collected from drilled boreholes while the surface water samples were collected from fishponds or water bodies (rivers) close to the oil spill sites. The samples taken from the oil spill sites were analysed to determine the level of concentration of 10 Department of Petroleum Resource (DPR) specified heavy metals (Cd, Zn, Cu, Pb, Cr, Ba, Ni, Hg, As, and Co). BUCK Scientific Atomic Absorption Spectrophotometer (AAS) was used in detecting the concentration of the heavy metals. For the surface soil, Pb concentration in site A and B were significantly higher than what was obtained at site C, with a mean concentration of 219.70, 130.01 and 3.41mg/kg respectively for the three sites. The mean lead (Pb) concentration obtained in the surface soil was within DPR and United State Environmental Protection Agency (USEPA) acceptable limits. Barium also has significant concentration in both the surface soil and sub-surface soil. Kruskal Wallis test indicated significant difference in the Pb, Cd, Zn, Cu, Cr and Ba concentration in surface/topsoil among the three sites and also indicated significant difference in the concentrations of Pb, Cd, Cr, Ni, Ba and As in sub-surface soil among the sites. Little heavy metal concentration was found in both the groundwater and surface water. The study showed that even if some heavy metals were detected at the oil spill sites, they do not pose any serious health risk, as all the heavy metals in the four environmental media at the three sampling sites were below the national limit stipulated by the Department of Petroleum Resource (DPR), Nigeria.

The concentrations of trace metals; Lead (Pb), Iron (Fe), Copper (Cu), Zinc (Zn) and Cadmium (Cd) were determined in water, sediment and biota (Fish and plankton) from Ikpukulu-ama creek in Port Harcourt, Nigeria. The metals were analyzed using Atomic Absorption Spectrphotometer (AAS 500). Concentrations of metals in water were in the order of Cd<Cu<Pb<Zn<Fe, in sediments Cd<Cu<Pb<Zn<Fe, in fish Cd<Cu<Pb<Zn<Fe while in plankton the order of concentration were Cd=Pb<Cu<Zn<Fe. The mean concentrations of metals in surface water (mg/L) were 5.2, 0.83, 0.03, 0.46, and 0.01 for Fe, Zn, Cu, Pb and Cd respectively, in sediments (mg/g) the values were 16.0, 0.65, 0.09, 0.32, and 0.01 for the same metals. The mean concentrations of metals in fish (mg/g) were Fe (2.96), Zn (1.87), Cu (0.03), Pb (0.08) and Cd (<0.001), while for plankton (mg/L) were Fe (13.2), Zn (2.09), Cu (0.06), Pb (<0.001) and Cd (<0.001). The pollution index in the sediment was low. Trace metal concentrations in water, sediment and biota were below the maximum permissible levels recommended by National standard, but aquatic environment should be monitored regularly to avoid excess intake of metal into the water body.
