Evaluating the Environmental Impacts of Poultry Farming on Stream Water Quality: A Study From Abeokuta, Nigeria

摘要

The results obtained from the analysis of physicochemical parameters of the study stream revealed that the former poultry operation adversely affected water quality parameters by increasing biochemical oxygen demand, turbidity, cadmium, and total coliform, and decreasing the dissolved oxygen at the point at which poultry wastes entered Alakata stream. Further, phosphate, total coliform, cadmium, nitrate, and lead values were present in concentrations that exceeded international permissible limits for drinking water. Alakata stream has been heavily contaminated by poultry wastes, and it is unfit for drinking or for domestic purposes. The poultry operation has deteriorated the water quality of Alakata stream, and its poor water quality could have adverse health effects on humans if they were to consume it.
