Assessment of Water Quality and Oxidative Stress Response in Fish Sampled from Selected Rivers in Ogbomoso, South-West Nigeria
Abstract
Surface and underground water face the challenge of pollution arising from indiscriminate dumping of wastes and agrochemical leachates. Two rivers, Ikose and Owode located at the countryside of Ogbomoso town South-West of Nigeria were selected for quality assessment in comparison with water sourced from a commercial fish farm. Physicochemical parameters including pH, temperature, turbidity, biochemical oxygen demand, chemical oxygen demand and electrical conductivity were determined from the water samples. Water quality indices (WQI) of the water samples were calculated from the summation of the physicochemical characteristics of the rivers using a published model. Water analyses were carried out using liquid-liquid extraction and GC-MS technique. The lengths and weights of the fish samples were determined and thereafter homogenized for biochemical analyses. Hepatosomatic Index (HSI) as well as Fulton’s Condition Factor (K) was calculated from the fish length, body weight and liver weight. Statistical analysis was carried out; and the means were considered significantly different when p<0.05. The physicochemical characteristics of the three water sources were found to be significantly different from one another. Results of water analysis identified harmful chemical pollutants from all the samples. WQI of all the water samples were higher than the permitted level for purity. The values of HSI and K of the fish samples from the rivers were lower than those from the commercial farm. Biochemical tests of oxidative stress and exposure markers were positive in all the fish sample homogenates though less in the commercial fish. It is concluded that the water and fish from the rivers were not suitable for human consumption.
