In 5000-year-old premolars from Nubia and in 500-year-old teeth from Greenland, the lead concentrations were very low; modern teeth contained 10-100 times more lead. In contrast, cadmium concentrations varied by 30-fold in the two prehistorical populations; modern-day cadmium levels were in the lower range of this interval. These data suggest that, when compared to preindustrial exposures, the impact of current environmental lead pollution is considerable, while that of cadmium pollution is much less.
