Information on the contents of trace elements in hair from 144 male children is given. The contents of Ca
Mn
Fe
Cu
Zn and Pb were measured by XRF. It was found that the contents of Fe
Cu
Zn in hair from MBD patients were remarkably lower than normal. These changes have an influence on the nervous system. Multi-discriminant analysis results showed that some correlations exist between every trace element.
