| dc.description.abstract | The effect of 3% C0 ₂ exposure on zinc balance of human subjects was studied. Four volunteer airmen were studied over a 56 day period, which was divided into a control period of 14 days, an experimental period of 28 days, and a post-experimental, recovery period of 14 days. During the duration of the study, urine, feces and serum samples were collected and mineral analysis were conducted. During hypercapnia there is an increase of 5 ug/100 ml. in serum zinc level and a decrease of 16.2 ug/100 ml of urinary zinc level. This seems to indicate that the body has an apparent tendency to retain zinc. I t is also speculated that the variation in zinc balance is transient and it tends to return to normal, once the stress is removed. An increase of urinary calcium with no apparent change in serum level also was noted during the experimental period. Urinary inorganic phosphorus had a corresponding increase during this period. | en |
