Geochemical Partitioning of Some Heavy Metals in Dumpsite Soils in Kaduna Metropolis, Nigeria
Journal Title: International Journal of Research in Chemistry and Environment (IJRCE) - Year 2013, Vol 3, Issue 3
Abstract
Heavy metals are potentially toxic to human life and the environment. Metal toxicity depends on chemical associations in soils. Therefore determination of the chemical form of metals in soils is important in order to evaluate its mobility and bioavailability. Sequential extraction was used to fractionate Arsenic (As), Cadmium (Cd), and Lead (Pb) from ten dumpsites soils in Kaduna metropolis, Nigeria into six geochemical fractions: water soluble, exchangeable, carbonate, Fe-Mn oxide, organic, residual fraction. On the average, amount of heavy metals bound to each fraction differed significantly according to metal type, sites and across the seasons. The heavy metals were distributed almost evenly across the non-residual and residual fractions. The apparent mobility and potential bioavailability for these three metals in the soils were: Cd > Pb > As. Metal distributions in different chemical fractions in these samples depended on respective total metal concentrations, except for Cd. The study indicated that consumption of plants grown on these sites could pose health hazard to man.
