Two pre-Hispanic mummies from the Andean coast, belonging to a corpus of 16 mummies from the San Miguel de Azapa (Arica, Chile), were radiocarbon dated and analyzed in order to replace them in their historical context and to study the conservation state of the hair fibers and the heavy metal presence. The radiocarbon dating placed both mummies in the Formative period (1700 years BC to 500 years AD). Global and elemental analyses were performed using scanning electron microscopy coupled with energy dispersive X-ray spectroscopy and using X-ray fluorescence spectroscopy. These combined techniques enabled to prove the good global conservation state of the mummies' hair and to detect iron, lead, bromide and also arsenic in some cases, in significant amounts inside the hair fibers. Fourier transformed infra-red spectroscopy seemed to prove the good conservation state of the hair surface at a structural level that is why the conservation of hair proteins at a molecular level will be investigated by a proteomics approach in future work.
来自安第斯海岸的两具前西班牙时期木乃伊，属于圣米格尔·德阿萨帕（智利阿里卡）的16具木乃伊样本，对其进行了放射性碳年代测定和分析，以便将它们置于其历史背景中，并研究毛发纤维的保存状态和重金属的存在情况。放射性碳年代测定将这两具木乃伊都定位于形成期（公元前1700年至公元500年）。使用扫描电子显微镜结合能量色散X射线光谱法以及X射线荧光光谱法进行了整体和元素分析。这些联合技术能够证明木乃伊毛发的整体保存状态良好，并在毛发纤维内部检测到大量的铁、铅、溴化物，在某些情况下还检测到了砷。傅里叶变换红外光谱似乎在结构层面证明了毛发表面的良好保存状态，这就是为什么在未来的工作中将通过蛋白质组学方法研究毛发蛋白质在分子水平上的保存情况。
