Assessment of Nutrient Load in Unwana River

Chukwu Iheanacho Egbe, Ibe Emmanuel Agwor, John Ama Ibiam

Abstract


ABSTRACT

Water samples from different locations of Unwana River were drawn. The parameters analyzed were NH3-N, NO3-, NO2- and PO4-3 and these were done using uv-spectrophotometric method. The results of the samples showed that NH3-N concentrations in the five locations ranged 0.800.24 - 1.630.17 mg/L, NO3-, 0.440.19 - 1.800.33 mg/L,NO2- 0.060.04 - 0.200.09 mg/L and PO4-3. 11.150.72 - 26.200.24 mg/L. The results showed that only NO3- were below the WHO (2012) maximum permissible drinking water standard and while NH4-N, NO2- and PO4-3 were above the WHO drinking water standard and do pose dangers to the users of the water. High concentrations of NO2- pose serious threat as it can cause methemoglobinemia (blue baby syndrome) in children using the water. Due to high concentrations of NO2-, the water should be given adequate treatment before usage.
