Investigation of the extent of Heavy Metal Pollution inSedimentsand SludgeUsingAtomic Absorption Spectroscopy (AAS)

The method of Atomic Absorption Spectroscopy has been employed to analyze three heavy elements; Cu, Fe and Mn in cored samples from the underlying sediments from Ahmadu Bello University Water Dam. Additionally, the variations observed for Fe and Mn further showed the capability of the AAS technique to distinguish small difference in concentrations of these elements in samples collected from nearly the same environment. By the results presented in this work for Mn, Fe and Cu, the chemical baseline data have been further enriched for these elements in the A.B.U Water Dam.
