The concentration of Cadmium (Cd), Chromium (Cr), Copper (Cu), Iron (Fe), Nickel (Ni), Lead (Pb) and Zinc (Zn) which may affect human health and the "health" of the aquatic ecosystem were determine in the River Ijana Ekpan, using a pye unicam Atomic Absorption Spectrometry SP model 2900. The level of heavy metal in the study area varied between Cd (0.010 ± 0.004mgl -1 ) and (0.100 ±0.014mg1 -1 ); Cr (0.037 ± 0.006mg1 -1 ) and (0.067 ± 0.020mg1 -1 ), Cu (0.020 ± 0.004mg1 -1 ) and (0.050 ± 0.029mg1 -1 ); Fe (0.046 ± 0.007 mg1 -1 ) and (0.229 ± 0.008mg1 -1 ); Ni (0.030 ± 0.004mg1 -1 ) and (0.080 ± 0.010mg1 -1 ); Pb (0.025 ± 0.006mg1 -1 ) and (0.058 ± 0.008mg1
