Seasonal influences on levels and eutrophication potential of nutrients in Imo River, Nigeria
Journal Title: Journal of Biodiversity and Environmental Sciences (JBES) - Year 2011, Vol 1, Issue 4
Abstract
Water eutrophication is one of the most challenging environmental problems in fresh water systems. Effects of seasonal changes on levels of nutrients in Imo River and possible environmental consequences have been determined. Water samples were collected seasonally at major points and subjected to standard chemical analysis. The result showed significant variations in seasons (P < 0.05) for nitrate (mg/L) at all the locations; Ekenobizi, Udo, Owerrinta, Alulu, Owaza, Obigbo, and Akwette. There were significant variations in seasons (P < 0.05) for phosphate (mg/L) at Owerrinta, Owaza, Obigbo, and Akwette. While, there were no significant variations in seasons (P > 0.05) for phosphate at Ekenobizi, Udo, and Alulu. The nutrient levels increased higher in the rainy than dry season and might lead to eutrophication if not controlled.
