Abattoir, effluent, physicochemical parameters, microorganisms


Effluent samples from three points (discharge point, upstream and downstream) were collected from Akunlemu abattoir in Oyo town, Nigeria. Physicochemical parameters and microbiological analyses of the samples were carried out. Total viable count was by pour plate technique and the most probable number (MPN)  by the multiple tube fermentation technique. The temperatures of the samples were between 31.0-33.30C and pH range between 5.83-6.80. The total viable count for all the samples exceeded the limit of 1x102 cfu/ml which was between 8.3x105-10.2x105 cfu/ml, with sample C recording the highest value. All the samples exceeded the limits for Total dissolved solid (TDS), Total solid (TS), Total suspended solid (TSS), Biochemical oxygen demand (BOD) and Chemical oxygen demand (COD) with sample B having the highest values – BOD 2765 mg/L, COD 5185 mg/L TSS 2981 mg/L, TDS 550 mg/L and TS 3528 mg/L. Microorganisms isolated included Proteus sp, Staphylococcus aureus, Escherichia coli, Klebsiella sp Pseudomonas sp, Aspergillus niger, A. flavus, Fusarium sp and Penicillium sp.
