Abstract

Concentrations of some trace elements such as Zn, Pb, Cr, Cd, Ni and Cu in surface and ground water in Agepanu and environs were evaluated after acid digestion by atomic absorption spectrophotmetry. The concentrations of the elements ranged from 0.084 – 0104 mgl-1 for Zn; 0.007 – 0.087 mgl-1 for Cr, less than 0.002 mgl-1 for Pb, 0.075 – 0.099 mgl-1 for Cu ; less than 0.05 mgl-1 for Cd and less than 0.002 mgl-1 for Ni. The concentrations of the examined elements were below the WHO, FMEV safe limits in surface and groundwater except for chromium which was slightly higher than the safe limit in Afiangbe.
