![]() Enhanced concentrations and significant spatial variation was recorded for heavy metals in sediments from Oberrakai Creek as against what obtains in sediments from Mbat-Abbiati Creek. Results show that the measured heavy metals have an abundance trend in the order Zn>Cr>Ni>Cu>Pb>As>Cd for sediments from Mbat-Abbiati and Zn>Cr>Ni>Pb>Cu>As>Cd for sediments from Oberakkai Creek. The present study focused on the investigation of the current level and distribution of seven heavy metals (Pb, Zn, Cu, Ni, Cr, Cd, As) collected from surface sediment at 12 stations, located within Mbat-Abbiati and Oberakkai Creeks of the Great Kwa River. In southeastern Nigeria, the Great Kwa River watershed which was originally covered by tropical rainforest has now become a beehive of various agricultural, extractive and industrial activities. ![]()
