Cr and Ti in hair of 63 leukemia patients have been determined by XRF. Compared with 115 normal adults
the hair levels of Zn
Cu and Ca in patients of both sexes were significantly decreased and the Pb level was dramatically increased (p<0.05 or p< 0.001). In addition
the hair contents of Ni
Fe
Mn and Cr in male patients were also significantly increased
while the hair Sr content in female patients was significantly decreased (p<0.05 or p< 0.001). It seems that the higher incidence of leukemia in male than in female was related to higher hair levels of Mn
