Bacteriological and Physicochemical Characteristics of Abattoir Effluents from Ado - Ekiti Municipal Abattoir, Ekiti State, Nigeria
Journal Title: Scholars Academic Journal of Biosciences - Year 2015, Vol 3, Issue 10
Abstract
Abstract: Bacteriological and physicochemical contents of effluents from Ado - Ekiti Municipal abattoir in Ekiti State, Southwestern, Nigeria were studied. Effluent samples from four points; slaughter slab, drainage within the abattoir, drainage just outside the abattoir and drainage 20metres away from the abattoir were analyzed. Effluents samples were collected for the determination of pH, Temperature, Total Dissolved Solids (TDS); Total Suspended Solids (TSS); Biochemical Oxygen Demand (BOD); Coliforms; Pseudomonas aeruginosa; Faecal streptococcus and Clostridium perfringens. TDS and TSS were significantly (p<0.05) higher in drainage within abattoir than the slaughter slab however BOD, pH, nitrate, phosphate, turbidity and temperature were similar (p>0.05) statistically, also TDS, TSS, BOD, nitrate and turbidity were significantly (p<0.05) higher in the drainage 20metres away from the abattoir than the drainage just outside the abattoir while other parameters like pH, phosphate, and temperature were similar (p>0.05) statistically. Coliforms, Pseudomonas aeruginosa, Faecal streptococci and Clostridium perfringes values obtained for effluents samples collected from the slaughter slab, drainage within the abattoir, drainage just outside the abattoir and drainage 20metres away from the abattoir were statistically different. The presence of high contaminants and microbial load in abattoir effluents with its environmental pollution tendencies especially surface water corroborates the fact that proper effluents treatment should be done before its discharge into the environment. Keywords: Abattoir, Water, Physicochemical, Bacteriological, Sanitary, Total Suspended Solids, Total Dissolved Solids, Biochemical Oxygen Demand, Coliforms, Public Health.
