  • Mineral analysis of ancient Peruvian hair

    Open Access•R A Benfer, John T Typpo et al.•ARTICLE•American Journal of Physical…•1978•Citada por: 9•Referências: 10

    Ancient Peruvian hair has been excavated from a series of archaeological sites on the Peruvian coast. After careful cleaning, examination by scanning electron microscopy revealed most of the samples to be in a state of preservation comparable to modern hair. No evidence of pathological conditions was observed. Trace metal composition was determined by atomic absorption and flame emission spectrophotometry and nitrogen by Kjeldahl analysis, produc…
