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.
