ABSTRACT
Soil samples were gathered from a scrap heap site at Uwelu spear parts, Egor L.G.A. and a control site at Ekosodin, Ovia North East L.G.A. in Benin City, Edo BCR sequential extraction assessed Pb, Zn, Cu, Cr, and Cd after physicochemical characterization. After metal fractionation into acid extractable, reducible, and oxidizable fractions, aqua regia was used. Flame atomic absorption spectrophotometry examined metals.
EC, CEC, and pH rose with soil depth. Both samples had sandy soil. In the acid extractable, reducible, and oxidizable fractions, zinc was most mobile, followed by copper, chromium, lead, and cadmium. Copper was the least mobile residual fraction element, followed by zinc and chromium. Due to mobility, these metals must be monitored in soil. Metals in soils can pollute groundwater, aquatic habitats, vegetation, and the environment, causing health issues. Please clarify.
