【Abstract】 The contents of Zn, Cu. Fe, Mn and Mg of hair in normal old person in Yanbian Korean Autonomous Prefecture were measured by atomic absorption spectrometry. The results indicates that the contents of Mn and Mg in the group above 90 years old are lower than those in 65 and 76 years old group. The contents of Zn. Cu and Fe are no significant difference among 65 to 108 years old. The content of Zn in Korean is lower than that in Chinese, The content of Cu in Man race is lower than that in Chinese and Korean.
