This study documents the baseline geochemistry of sediments in portions of the Eastern Niger Delta, focusing on the distribution of selected heavy metals (Pb, Zn, Cd, Cr, As and Ni). Concentration level of metals was determined through Atomic Absorption Spectrophotometry (AAS) and results interpreted with statistical techniques. Interrelations between elements reveal a control by three dominant geogenic factors. The result of this study shows that heavy metal geochemistry of sediments is related to regional and local geology with minor imprints of anthropogenic activities.
