Physicochemical Assessment of Vulnerability of the River Ebenyi in Eha-Amufu and Environs, Southeast Nigeria | Chapter 05 | Recent Advances in Biological Research Vol. 6
Aim: Physicochemical assessment of the surface water sourced from River Ebenyi and its tributaries in Eha-Amufu and environs, Isu-Uzo Local Government Area of Enugu State of Nigeria. Place and Duration: Eha-Amufu and environs, Isu-Uzo Local Government Area of Enugu State of Nigeria May to July, 2017. Study Design: Experimental design. Methodology: Water samples were spatially collected along the river and stream channels in Eha-Amufu and the adjoining Ihenyi, Amaede, Mgbuji, Umuhu, Agamede and Odobudo villages. Parameters analysed include pH, dissolved oxygen (DO), biological oxygen demand (BOD), chemical oxygen demand (COD), Total hardness (TH), Lead (Pb), Copper (Cu), Cadmium (Cd), Chromium (Cr), Zinc (Zn), Nitrate, Phosphate, Chloride and Sulphate. Results: The concentrations of Cd (0.02-0.05 mg/l) and Pb (0.37-0.77 mg/l) exceeded the maximum limit of the range of values considered as safe by the World Health Organisation (WHO). Conductivity (37.14 – 63.30 µs/cm), ...
