ORIGINAL RESEARCH ARTICLE - Effects of abattoir activities on the water quality of Oko-Oba river in Agege, Lagos, Nigeria: a seasonal variation assessment

Oluwatoyin T. Fatunsin, Ayodele Adetola, Oluwasegun T. Adetunde


Surface water from the Oko-Oba River in Agege, Lagos Nigeria which runs beside the Oko-Oba Abattoir was assessed for its physicochemical quality in relation to temporary seasonal variation. The samples were collected in May and September 2019 (wet and dry season) and analysed for physicochemical (including some potentially toxic metals (PTMs)) and microbiological parameters using standard protocols of American Public Health Organization (APHA) and American Society for Testing and Materials (ASTM). Many physicochemical and microbiological parameters analysed for the samples did not meet regulatory standards for surface water. Some significant correlations were observed between the seasons, sampling points and parameters. The results of this study showed that seasonal variations affected some the water quality parameters of the Oko-Oba River. Further studies are recommended to provide information on the effect of the Abattoir activities on aquatic life in other to ensure sustainable river bodies.
