- We obtained high-resolution elemental maps (pixel size ranging between 10 and 20 ?m) of the dental crown. - The two Roman teeth showed clear Pb variation through the crown, highly correlated with enamel growth trajectories, likely linked to lead environmental exposure during the individual's lifetime. - Individual SCR313: Pb peak at ~410 days, visible in both dentine and enamel. - Individual SCR249: low pre-natal Pb levels, that increase post-natally; a Pb peak coincides with the neonatal line. - We identified several areas in both enamel and dentine affected by post-depositional processes.

Abstract
- We obtained high-resolution elemental maps (pixel size ranging between 10 and 20 ?m) of the dental crown. - The two Roman teeth showed clear Pb variation through the crown, highly correlated with enamel growth trajectories, likely linked to lead environmental exposure during the individual's lifetime. - Individual SCR313: Pb peak at ~410 days, visible in both dentine and enamel. - Individual SCR249: low pre-natal Pb levels, that increase post-natally; a Pb peak coincides with the neonatal line. - We identified several areas in both enamel and dentine affected by post-depositional processes.File in questo prodotto:
