Abstract
Water is one of the most common natural resources that profoundly influence life. Water pollution occurs, when there is adverse change in the physical, chemical or biological condition of the water, which harmfully affects the quality of human life including other animals and plants life. Studies on River water pollution and their implication to public health have been ongoing. An assessment of the seasonal changes in the physicochemical properties of Ikpoba River, Benin City, Nigeria polluted by brewery effluent was carried out between the months of January to March and May to July for the dry and wet seasons’ respectively. Standard procedures were employed in this study. Our results showed a temperature range of 230C to 330C. The dry season discharge point (DP) sample had the highest temperature. The pH values of most of the samples were within the optimum range for aquatic organisms (6.5–9.0). There was a significant difference (p<0.05) in pH along the sampling points and days in the two seasons. The range of the electrical conductivity was 70–1750 µs/cm in dry season and 90.2–1320 µs/cm in wet season. DP samples had the highest values followed by the downstream (DS) samples with the upstream (US) samples having the lowest values. Salinity in the dry season was higher than those of the wet season. Physical and spectrophotometric assessment showed remarkable color change particularly in the DP samples followed by the DS samples. The effect was mild in the US samples. In this study, turbidity values ranged from 2.8 NTU to 16.1 NTU with higher values during the wet season. Total suspended solid (TSS) ranged from 4.2 mg/l–39.9 mg/l. Total dissolved solid (TDS) were higher in the dry season. There was significant difference (p<0.05) in DO along the sampling points and days in dry and wet seasons. The chemical oxygen demand (COD) values were much higher than those of Biochemical Oxygen Demand (BOD5). There was significant difference (p<0.05) in COD and BOD5 along the sampling points and days in the two seasons. Carbonate, sodium, potassium, phosphorus, ammonium, nitrate, chloride and sulphate. There was significant difference (p<0.05) in nitrate composition along the sampling points and days in the two seasons. There was significant difference (p<0.05) in lead composition along the sampling point in the two seasons except on Day 42 at DS and US. There was presence of hydrocarbon (HC) in water the samples, which showed significant difference (p<0.05) along the sampling points throughout the period of study. The physicochemical properties of the river showed that it was unfit for human consumption and is a cause for public health concern.
