23 hair trace elements were determined with the method of Inductively Coupled plasma Quantometer (ICP-AEP) in 85 cases of schizophrenics and 65 cases of normal controls. The results indicated that: there were no significant differences between age and the samples of the two groups; Significant sex differences were observed in schizophrenics, 11 trace elements were higher in female (P less than 0.01), 5 trace elements were increased in male (P less than 0.01); As a whole, 17 trace elements were decreased in schizophrenics than normal controls, the differences were significant (P less than 0.01).
