Abstract
Water plays a vital role in the day to day activities of man and over the years the quality of water bodies both in the rural and urban areas has received increasing research interest from scientists. The aim of this study was to investigate various physicochemical properties of pharmaceutical wastewater in Sango-Ota, Ogun state. Characterization of wastewater was evaluated in terms of temperature, pH, total suspended solids (TSS), total dissolved solids (TDS), Biochemical oxygen demand (BOD), Chemical oxygen demand (COD), and also to evaluate the presence of some heavy metals. The level of pollution of this effluent was compared with guidelines prescribed by World Health Organization (WHO) and The Federal Environmental Protection Agency (FEPA). The temperature ranged from 27.5-29 oC, pH ranged from 7.17-7.41, Total Alkalinity ranged from 259-289 mg/L, Chloride ranged from 5-10 mg/L, water hardness ranged from 350-365 mg/L, total suspended solids (TSS) ranged from 259-289 mg/L, total dissolved solids (TDS) ranged from 275-322 mg/L, Biochemical oxygen demand (BOD) ranged from 33-45 mg/L, Chemical oxygen demand (COD) ranged from 9-10 mg/L, Nitrates ranged from 8-9 mg/L, Phosphate ranged from 4.1-4.2 mg/L and dissolved oxygen (DO) ranged from 3-4 mg/L. The results of the heavy metals revealed that cadmium was not detectable, copper was within the acceptable limits according to FEPA with values ranging from 0.17 to 0.28 mg/L while iron and zinc were above the FEPA limits with values ranging from 33 to 35 mg/L and 1.48 to 1.53 mg/L respectively. This study reveals the need for the regulatory bodies to ensure that adequate effluent treatment methods are strictly adhered to by the pharmaceutical plants before their discharge to surface water to reduce their potential environmental hazards.
