The association between lead concentrations in teeth and domestic water lead concentrations

Tooth lead levels have been measured in 109 children living in Glasgow. A significant association has been demonstrated between molar tooth lead concentrations and domestic drinking water lead concentrations. Tooth lead concentrations were found to be greater the longer a child had liver in older housing with lead plumbing during foetal life and following birth. Tooth lead concentrations were also found to be age-related although no difference with respect to social class could be found.
