Isotopic data obtained from human remains can provide information about an individual's origin, migration, and diet. We evaluate the usefulness of carbon, oxygen, strontium, and lead isotopes for forensic investigations by comparing data from Bulgarian teeth with data from other regions. Geo-referencing based on oxygen or strontium isotopes can be misleading due to overlap with other countries in Europe and other continents. Carbon and lead isotopes, in combination with oxygen and strontium isotopes, provide the most useful information for identification of local vs foreigner status. In particular, high-precision Pb isotopes show a distinct "Bulgarian" range; however, it is possible that individuals from other countries in Eastern Europe and/or central to western Asia could have overlapping isotopic values. Additional high-precision multi-isotope data from modern humans from different regions in the world are required to transition from speculative to more quantitative estimation of a geographical place of origin for unidentified human remains.
从人类遗骸中获取的同位素数据可以提供有关个人的出身、迁徙和饮食的信息。我们通过比较保加利亚牙齿的数据与其他地区的数据，评估碳、氧、锶和铅同位素在法医调查中的有用性。由于与欧洲其他国家和其他大陆存在重叠，基于氧或锶同位素的地理定位可能会产生误导。碳和铅同位素，与氧和锶同位素相结合，为识别本地人还是外国人身份提供了最有用的信息。特别是，高精度铅同位素显示出明显的“保加利亚”范围；然而，来自东欧其他国家和/或中亚至西亚的个人可能具有重叠的同位素值。需要来自世界不同地区现代人类的更多高精度多同位素数据，以便从不太确定的推测过渡到对身份不明的人类遗骸的地理起源进行更定量的估计。
