As an example of the mapping of human hair composition, the territory of Uzbekistan was chosen. The data and the maps obtained were compared with the environmental situation and medical statistics. World maps were drawn on the basis of various authors' data. The possibility of using human hair for radioactivity studies is discussed on the basis of data obtained in the Chemobyl area. The proposed scheme of human hair analysis may be used for world mapping for chemical elements, radionuclides, pesticides, dioxines, PCBs, etc., either to picture the global situation or as a health status on the level of populations.
