Lead and other metals distribution in local cooking salt from the fofi salt‐ spring in akwana, middle benue trough, Nigeria

Abstract

Energy Dispersive X‐ray Fluorescence(EDXRF) technique has been used to determine the concentrations of lead(Pb) and other heavy metals in local cooking salts(LCS) from Akwana village, Middle Benue Trough, Nigeria. The comparison of the distribution of these metals in LCS, ‘fake’ salt(FS) and the usual common salts(CS) are given. Lead was found to be enriched in LCS by factor exceeding 200 times compared to the other salts. The origin of Pb contamination in the LCS is examined and its effects on the inhabitants of the village are considered.
