Carbon and nitrogen isotope profiles were obtained from incremental dentine analysis of 19 non‐adults from a cemetery in Riga, Latvia. The research compared the life histories and diet between people buried in two mass graves and the general cemetery. The δ13C profiles of several children from the mass graves were similar but did not resemble the patterns seen in children from the general cemetery, suggesting that they probably represented a different population group. The rise in δ15N values towards the end of the life of four individuals from one mass grave suggests they were victims of an historically documented famine.

调查拉脱维亚里加（公元 15 至 17 世纪）埋葬在圣格特鲁德教堂公墓的儿童的饮食生活史和流动性

碳和氮同位素分布是从拉脱维亚里加的一个墓地的 19 名非成年人的增量牙本质分析中获得的。该研究比较了埋在两个乱葬坑和普通墓地中的人们的生活史和饮食。来自乱葬坑的几名儿童的 δ13C 剖面相似，但与普通墓地儿童的模式不同，这表明他们可能代表了不同的人群。一个万人坑中的四个人在生命即将结束时 δ15N 值的上升表明他们是历史记录饥荒的受害者。
