Abstract:

Abattoir effluents are known to degrade the quality of receiving water bodies. This study assesses the physiochemical parameters of water side river of which the abattoir is located at Obinze in Owerri west L.G.A, Imo State Nigeria. Water samples were collected from three different points of the water bodies namely the upstream i.e. the point of discharge, middle stream and downstream and analyzed for pH. Temperature, Conductivity Turbidity, Nitrate, Phosphate, Biological Oxygen Demand (B.O.D) and Dissolve Oxygen (D.O) . The mean values of these mean parameters were as follows; pH 6.4, Temperature 24.6oc, Conductivity 162.3us/cm, Turbidity 29.3NTU, Nitrate 232.3, Phosphate 59.8, B.O.D 41mg/l and D.O 39.9mg/l. From the result obtained, some of the parameters tested were above the NESREA’S permissible limit except for temperature, pH, D.O, which are within the NESREA’s permissible limits. The high levels of some of these parameters showed that the effluent from the Obinze abattoir in Owerri West L.G.A Imo State Nigeria contributed to the pollution of the stream.
