| contents | Archaeological and contemporary human hair composition and morphology Josefina Mansilla Pedro Bosch María Teresa Menéndez Carmen Pijoan Carlos Flores María del Carmen López Enrique Lima Ilán Leboreiro Antropología Hair mummy human scalp cortex Contemporary and mummy hair samples are characterized and compared, using modern chemical and physical characterization methods. It is found that in cave conditions mummy hair can be preserved even if it interacts with environmental dirt or soil, X-ray diffraction and infrared spectroscopy results. Hair is an ion exchanger and the exposure to earth and water can facilitate the interaction of some elements with hair as shown by X-ray fluorescence, energy dispersive spectroscopy and neutron activation analysis. Post mortem degradation is detected through the reaction of cystine and through the partial collapse of the scale arrangement. The mummy hair scales become less ordered and the hair surface less smooth, such features were clearly observed by scanning electron microscopy and atomic force microscopy. The presented interdisciplinary results show that alteration of hair initiates in the core but scales are often well preserved. The features found in mummy hair suggest that the correlation between chemical composition and health or nutrition of ancient people should be carefully evaluated due to environmental contamination. 2011 artículo científico 0716-1182 https://www.redalyc.org/articulo.oa?id=32620742010 http://www.redalyc.org/revista.oa?id=326 Chungara, Revista de Antropología Chilena application/pdf Universidad de Tarapacá Chungara, Revista de Antropología Chilena (Chile) Num.2 Vol.43 |
