Abstract
Pb concentrations in human bone and tooth samples from a 11th century mining community were analysed to study the influence of long-term burial in polluted soils. PIXE and RBS analysis with 20–300 μm proton beams and 300 μm 4He+beams at the University of Freiburg Van de Graaff laboratory and less than 5 μm at the University of Melbourne Microanalytical Research Centre was performed and strongly increased Pb levels at outer and inner bone and tooth surfaces were found, reaching more than 1000 ppm in some of the bone samples, and decreasing to equilibrium levels in the order of 5–10 ppm in some non-porous inner sections of the analysed bones and teeth.
