Abstract

Background: This research examined the surface water ecotoxicological risk of untreated abattoir effluent discharged directly into nearby rivers that could result in likely damage to aquatic species. Objective: The study was aimed at evaluating the deleterious ecological effects resulting from discharge of abattoir effluent into surface waters of some selected rivers in Effurun metropolis, Delta State, Nigeria. Method: The American Public Health Association (APHA) standard protocol was used for testing the water quality in addition to the Surface Water Ecotoxicological Risk Assessment Matrix (SW-ERAM), which was used to evaluate the ecological effects. Results: The pH values ranged from 5.48±0.14 (Agbaroh river) to 6.76±0.18 (Agbaroh abattoir effluent) indicating a slightly acidic environment. The waters were moderately to highly turbid with values between 10±1 NTU and 196.11±9.0 NTU. Total suspended solids (TSS) were relatively high and varied from 14±1.0 (Ugbomro river - control) to 242±12 (Ekpan abattoir effluent). Besides the control, the water samples from all the locations showed high levels of total coliform bacteria. The risk level was rated high [5E or 25 (A, P, E)], which was designated as harmful and capable of affecting aquatic animals (A), plants (P) and the environment (E). Conclusion: The indication from this study is that continuous discharge of untreated abattoir effluent into surface waters may pose threat to aquatic species and human health.
