摘要:This study aims to assess how strontium, barium and calcium (138Ba/44Ca and 88Sr/44Ca) areincorporated into human hard tissue (enamel, dentin and bone). For this purpose we used laser ablationwith inductively-coupled plasma mass spectrometry (LA ICP-MS). Human hard tissue from anarchaeological series was analysed to determine isotope signals to investigate possible differencesbetween enamel, dentine and bone. Significant variance in the ratios was identified by tissue type. Themanner in which the type of hard tissue influences 138Ba/44Ca and 88Sr/44Ca ratios is discussed. Possiblereasons for distinct isotopic responses are individual ways of metabolism, tissue mineral incorporation,and individual differences in the elements’ absorption. The validity of dietary and migration studies,based on barium and strontium concentrations, are reconsidered. More than just for dietary andmigration pattern reconstruction, this method serves as a chemometric tool for human skeletal remains’discrimination. Using a discriminant function, we found substantial differentiation in the hard tissuesof investigated individuals.
