摘要

This study investigates level of pollution in the Ajegunle Creek. Water samples were collected and analyzed for five months. This physicochemical characteristics, cation content, nutrients and heavy metal levels varied across the three sampled stations. The mean physicochemical parameters are Temperature (23-29.5℃), TSS (9-43mg/l), TDS (386.3-15700mg/l), Turbidity (4.92-34.02NTU), Salinity (0.53-8.9%), Conductivity (679.3-25900 μS/cm), DO (0.1-4.8mg/l), BOD_5 (2-598mg/l), COD (10-2192mg/l), Total Hardness (82-972mg/l). There were variations in the nutrient values. The mean cation content was;potassium (3.62-151mg/l), Calcium (4.11-170.3mg/l), Silica (0.82-11.43mg/l), Sodium (135.1-4926.07mg/l) and Oil and grease (＜ 0.2 mg/l). Nitrate ion is the common form of nitrogen found in the study site. The metals concentrations recorded are arranged in order of their distributions in the three sampling stations as follows: Fe＞Zn＞Mn＞Cr＞Ni＞Cd＞Pb＞Cu. The seasonal influence as well as human induced stressors in the water confirmed that the Ajegunle creek in the Tin-Can Island area of Lagos is polluted.
