The multielement contents of boys' hair in "Ke-Shan" disease region and nondisease region are determined by means of the instrument neutron activation analysis method with long and short term irradiation. The domestic usual cleaning method for hair was compared with IAEA standard method. The partial standards used in our experiment are checked with NBS standard reference material and the results are satisfactory. The contents of 27 elements in 48 hair samples are determined and the preliminary rule of the distribution of some elements in human hair are obtained.
