Lead levels in deciduous teeth of children from selected urban areas in the Cape Peninsula
Abstract
The lead levels in shed deciduous teeth of children from two selected urban regions in the Cape Peninsula were compared. The average levels in the teeth of children living in the vicinity of two large industrial plants were: whole teeth 20,419 ppm, enamel 10,952 ppm, and dentine 22,733 ppm. The lead levels in teeth from children living in the vicinity of light industries were: whole teeth 16,556 ppm, enamel 2,919 ppm, and dentine 19,926 pp·m. These differences were significant at the 1% level (teeth and enamel) and 5% level (dentine).
