Mapping using human blood composition data.

The mapping of elemental composition using INAA on the base of whole blood and hair of inhabitants (2500 samples) was made in Uzbekistan (CIS). The average concentrations of 15 elements (24 for hair) were determined. The results obtained were compared to regional medical statistics. The correlations for various diseases were obtained. The maps of human blood composition in comparison to those for human hair composition seem to be less significant in terms of regional contamination (probably because of stronger homeostatic control of blood). On the other hand, specific changes of blood composition were detected for some occupational groups. Relationships of blood and hair elemental composition and their relative significance are discussed.
