Study of the vietamin B₁、B₂ C and minerals K、Na、Ca、 Mg、Fe、Zn、Cu was mad.the results showed that the intake of VB1、Ca was insufficient and took of 54. 9%, 57. 4%RDA.the loss of vitamin B₁、B₂、C in sweat and urine were 22. 11% 、 26. 77%、6. 21%of intake respecively. T he loss of mineral Kin sweat was 9. 3 as much as that in urine, T he loss of mineral Na、Fe、Zn、Cu in sweat was 20. 5, 30, 4. 6, 2. 4 as that in urine respectively. The average amount of serum K, Cu was in the lower of normal. many workers serum Na, Mg, Zn wer e lower, Mabey it was due to the loss of much sweat. This study supply the theory for requirement of mineral and vitamin.
