Abstract
Trace concentrations of lead and tin were analyzed in samples from around a lead smelter in Jos, Nigeria by x‐ray fluorescence spectrometery. Results obtained for lead showed very elevated lead levels in the soil samples (38–9934 ug/g) which are strongly indicative of gross pollution of the soil samples around the smelter. Concentrations of tin in the samples range from 20–1434 μg/g, dry weight. Factors influencing concentration in soil samples included soil depth and distance from smelter. Analytical accuracy was found to be in very good agreement with standard reference material. Typical precision values were between 0.6–1.3%.
