Variation of Ba/Ca and Sr/Ca response in human hard tissue from archaeological series dating back to the Early Bronze Age

Popis výsledku v původním jazyce

The aim of this study is to assess how strontium, barium and calcium (138Ba/44Ca and 88Sr/44Ca) incorporate into human hard tissue (enamel, dentin and bone). For the purpose of the study we used laser ablation with inductively coupled plasma mass spectrometry (LA ICP-MS). Human hard tissue from archaeological series were analysed to determine isotope signals to investigate possible differences between enamel, dentine and bone. Significant variance in ratios by tissue type was identified. The manner in which the type of hard tissue influences 138Ba/44Ca and 88Sr/44Ca ratios is discussed. Possible reasons for distinct isotopic responses are individual way of metabolism, tissue mineral incorporation, and individual differences in elements' absorption. The validity of dietary and migration studies, based on barium and strontium concentrations, are reconsidered. More than 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 hard tissues of all individuals.
