Abstract
Human teeth from pre-Columbian, colonial and contemporary population g roups have been analyzed by PIXE in order to evaluate the elemental ch anges, particularly those related to lead contents in the inhabitants of Mexico city. Minor changes of the Me/Ca ratios for Mn, Fe, Cu, Zn a nd Sr for the three populations were detected, Tn contrast, Pb content s showed significant differences among the three groups. In pre-Columb ian teeth no lead was found. Colonial teeth showed higher lead levels than contemporary ones. This result suggests that the glaze pottery in troduced by the Spaniards was the main source of lead in the colonial period.
