Preliminary studies of the distribution of some trace metals in the top soils of farmlands in the Jos tin mining areas

Abstract

 Trace metal concentration in arable soils from intensive tin mining areas of the Jos Plateaus was
 determined using an Energy Dispersive X-ray fluorescence (EDXRF) method, operated using a 22.1 KeV 25m Ci ¹⁰⁹Cd as the exciting source. The elements analysed in the soils are; Ti, V, Cr, Mn, Fe, Co,
 Sn, Ni, Pb, and Mo with concentrations of Fe, Ti, Sn and V being generally high while those of Ni, Pb
 and Mo were very low. This implies that the crop production in these areas could bring about the
 enrichment of the crops in certain elements.
