DESCRIPTION:Speakers: Valentina Zvereva (Nikolaev Institute of Inorganic C
 hemistry SB RAS)\nRecently the anomalously high content of copper in ancie
 nt hairs in royal burials of Xiongnu (I B.C. – I A.D.\, Northern Mongoli
 a) was discovered. Detailed investigation of all types of organic findings
  from the burials was performed by X-ray fluorescent technique with synchr
 otron radiation (SRXRF)\, X-ray microtomography\, X-ray absorption spectro
 scopy (XANES and EXAFS) and electron microscopy. The results revealed the 
 exogenous source of copper in ancient hairs and allow to exclude copper po
 isoning in lifetime [1]. There were 40 hair plaits in ancient burial site.
  Mercury was detected in all hair samples (up to 1200 ppm). High content o
 f Hg may be caused by the burial environment as well as the accumulation i
 n lifetime. Information\, which can elucidate the probable cause of such a
  high Hg content in hairs\, can be helpful in reconstruction of culture\, 
 life and technologies of ancient people. \nThe unique archaeological mater
 ial demands nondestructive analytical methods\, as SRXRF analysis and X-ra
 y microanalysis (µSRXRF).                  \nSRXRF methodology for Hg det
 ermination in archaeological hair samples\, mercury concentration in metal
 lic objects from the burial\, and information on cross-section distributio
 n of Hg in hair strand (µSRXRF) allow to determine probable source of mer
 cury in ancient hairs.         \n\n[1]. V. Trunova\, V. Zvereva\, N. Polos
