Abstract

Heavy metals are found naturally in the earth and they become concentrated as a result of natural and anthropogenic activities. Numerous researchers have worked on the pollution and contamination of toxic metals in the soils of the study area but none has been able to carry out sequential analysis and extraction of the heavy metals into different geochemical fractions. Therefore, this research adopted random sampling method across five locations at 100-200cm intervals at depth of 40m. The sediments collected were prepared for sequential analysis using standard chemical reagents which fractionate the metals into five defined phases such as exchangeable, carbonate, easily reducible, organic, and residual for heavy metals such as Ni, Zn, Co, Mn, Fe, Pb, Cr, Cd and Cu using atomic absorption spectrophotometer (AAS) Buck Scientific Model 205A. The results revealed that the residual, exchangeable, reducible, and organic fractions were the most active media where Fe, Mn, Zn, Pb and Cu were prominent and the correlation between them indicated a very strong bond. (0.9). Also, the result of mobility factor revealed that Cd has very high mobility and bioavailability in the studied area which constitutes a major threat to the ecosystem. Whereas, the enrichment factor of heavy metals in all the fractions indicated moderate to extremely high enrichment.
