Abstract

Human deciduous teeth from industrial East Helena, suburban Helena and the rural Helena Valley were contrasted for lead content. The highest level of tooth lead concentration was found in East Helena, where a lead smelter is located, followed closely by the Helena Valley. The teeth from Helena had the lowest lead concentration. The analysis was carried out by atomic absorption spectrophotometry at the Montana State Laboratory in Helena.
