Abstract:
Discharge of untreated effluents from Industries into the environment has been a major source of environmental pollution. This study focused on the physicochemical analyses of effluent generated from an aluminum producing company in Otta, Ogun State, Nigeria. Different physicochemical parameters as well as heavy metals were determined using various standard analytical methods, Flame Photometer, and Atomic Absorption Spectrophotometer (Spectra AA Varian 400 plus). The pH value was 12.04, TS (162.96 mg/L), TDS (152.60 mg/L), TSS (10.36 mg/L), total hardness (95.6 mg/L), total alkalinity (58.47 mg/L), DO (3.85 mg/L), BOD (5.35 mg/L), COD (7.85 mg/L), and chloride content (13.54 mg/L). The mineral analysis showed that the concentrations of investigated metals ranged from 0.01 mg/L (Cd) which was the lowest value to 21.70 mg/L (Na) which was the highest value. It was observed that many parameters investigated were outside the stipulated standards enacted by WHO and FEPA.
