Variation of Ba/Ca and Sr/Ca response in human hard tissue from archaeological series

Popis výsledku v původním jazyce

This study aims to assess how strontium, barium and calcium (138Ba/44Ca and88Sr/44Ca) are incorporated into human hard tissue (enamel, dentin and bone). For this purpose we used laser ablation with inductively-coupled plasma mass spectrometry (LA ICP-MS). Human hard tissue from an archaeological series was analysed to determine isotope signals to investigate possible differences between enamel, dentine and bone. Significant variance in the ratios was identified by tissue type. The manner in which the type of hard tissue influences138Ba/44Ca and88Sr/44Ca ratios is discussed. Possible reasons 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 and migration 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 tissues of investigated individuals. © 2016, Archaeological Centre Olomouc.
