Define working of Body surface in excretion of zinc in human?
Loss of zinc occurs due to the exfoliation of skin and sweating (0.7 -1.0 mg/day). Another route of zinc loss is hair, which contains 0.1-0.2 mg Zn/g hair. Strenuous exercise and elevated ambient temperatures can lead to high losses through perspiration. Considerable scientific efforts have been carried out to improve our understanding regarding the biological and physiological role of zinc.
