Concentration of mercury and zinc in 154 human hair samples collected from almost all districts in Japan was determined by neutron activation analysis. For mercury in hair of the Japanese, the mean value of 6.0 ppm was reported in 1966,and the use of mercuric pesticides was generally prohibited after 1967. Compared with the above value, the mean value of 6.4 ppm does not markedly reflect the influence of reduction of mercury residue in rice. Dentist's hair, which showed high values of mercury in the neutron activation analysis, was examined by colorimetry using dithizone. Although the mean value of mercury in 51 samples was 11.3 ppm, about two times higher compared with 6.4 ppm, the relation of mercury concentration to the age or length of handing of mercury was not clear. For zinc in hair, the mean value of 365 ppm was reported. Difference in concentration between male and female hair was large. Zinc in hair of 6 Kabuki actors was determined by colorimetry using Zincon. Because of the large concentration of 560 ppm compared with < 200 ppm of the mean values in their generation, effect of cosmetics on the zinc content in hair was great.
