我们提供了在美国中部收集的人发的碳(δ(13)C),氮(δ(15)N)和硫(δ(34)S)同位素比值的数据。这些元素被纳入饮食中的头发中,从而提供了饮食输入的记录,也可以记录地理空间模式。我们检测到美国各地头发δ(34)S值的区域差异,北方大平原的值最低,东部、西部和南部的值逐渐增加。相比之下,在人发δ(13)C和δ(15)N值的空间变化中未检测到统计学显著模式。使用δ(34)S值和地理信息系统方法,我们创建了一张地图(“硫等值线图”)。使用未包括在其生成中的头发样本来测试地图的准确性。我们的结论是,硫同位素分析可能是一种新的工具,调查运动和/或区域的起源的人类。
We present data on the carbon (δ(13)C), nitrogen (δ(15)N) and sulfur (δ(34)S) isotope ratios of human hair collected in the central portions of the USA. These elements are incorporated into hair from the diet and thus provide a record of dietary inputs that may also document geospatial patterns. We detected regional differences in hair δ(34)S values across the USA, with the lowest values in the northern Great Plains and increasing values towards the east, west and south. In contrast, no statistically significant patterns were detected in the spatial variation of human hair δ(13)C and δ(15)N values. Using δ(34)S values and a Geographic Information System approach, we created a map ('sulfur isoscape'). The accuracy of the map was tested using hair samples not included in its generation. We conclude that sulfur isotope analysis may represent a new tool to investigate the movements and/or region-of-origin of humans.
