Heavy Metal Contamination in Soils in Enyigba Pb & Zn

Abstract: Twelve {12} soil samples were collected from the Pb – Zn mining district of Enyigba, in the Abakaliki area of southeastern Nigeria and analyzed for As, Cd, Cu, Pb, Zn, Ni, Co, Mn, Ca and pH. The physicochemical analyses show that pH is fairly acidic to neutral (5.37.0) resulting from the dissolution of the sulphide ore waste dump
