Abstract

Potential toxic metals (Pb, Cu, Zn, Cd, Cr, Ni and Fe) concentrations in two selected refuse dumpsites (Apollo and Tonkere) soils in Ile-Ife, Nigeria were determined using Atomic Absorption Spectrometry to assess the pollution status of the areas. Control soils were also collected from areas with little or no anthropogenic inputs. Potential toxic metal concentrations in the refuse dumpsite soils were considerably higher than those of the control. Geo-accumulation index results indicated that the refuse dumpsites have unpolluted to moderate pollution for all the investigated metals, while pollution index results (> 1) suggested that the refuse dumpsites were contaminated with all the analyzed metals. Enrichment factor results indicated no enrichment for all the investigated metals. This might be connected with recent regular clearing of the dumpsites. Chemical speciation results showed relatively high bioavailability and mobility potential with a large proportion retained in the labile fraction. The study concluded that the studied dumpsites were still impacted with the analyzed potential toxic metals whose concentrations exceeded those of the control samples and standard permissible limits and that long-term exposure to these bioavailable metals might pose intrinsic hazards to human health. It is therefore recommended that clearing of the dumpsites should be consistent.
