摘要
A comparative analysis of trace element data of human skeletal material from four archaeological sites is presented. We show that the state of histomorphological preservation of bone, which is a measurement for the degree of its diagenetic alteration, closely corresponds to the Sr/Ca and Ba/Ca ratios at an infra-population level. This study challenges the validity of dietary studies that are based on the presently used procedures for sample preparation and subsequent evaluation of strontium and barium concentrations.
