Abstract:
Water samples were collected from Ogun River around the cattle market, Isheri, along Ibadan-Lagos express road, during the wet season to determine following parameters: temperature, pH, Total Solids (TS), Total Dissolved Solids (TDS), Oil and Grease (OLG), Dissolved Oxygen (DO), Chemical Oxygen Demand (COD), Alkalinity (ALK), Total Hardness (TH), Chloride (Cl), Sulphate (SO42–), Nitrate (NO3) and Phosphate (PO43–). In addition, heavy metals-Zn, Cd, Ni, Cu, Pb, Fe and Mn were also determined. The concentration of most metals in the water around the cattle market was generally higher than average world river water concentration and mean dissolved metal concentrations in inland and coastal waters in Africa. The levels of Cu and Zn were below the maximum permissible limits of Federal Environmental Protection Agency (FEPA) now Federal Ministry of Environment. Nitrogen: Phosphorus (N: P) ratio of the water around the market was greater than 0.5. This may be attributed to atmospheric fall out from vehicular emission, run off, other burning activities taking place in the market and decomposing organic matter arising from the market. This can accumulate over time to cause eutrophication, loss of microorganisms and other aquatic organisms including fish, by increasing their susceptibility to other environmental stresses due to prolonged exposure to low dissolved oxygen levels and high levels of toxic pollutants, which may be injurious to life forms in the water. Thus, the water around the cattle market is presently stressed and subjected to pollution mainly from the market.
