Urinary mineral output was observed in 4 young male volunteers on a constant diet before 5 days, during 11 days, and after 4 days exposure to 30 torr CO2 in air at a barometric pressure of 750 torr. The subjects, collectively, showed significant variation with time in daily urinary volume and output of zinc, magnesium, calcium, and phosphate, but not in output of creatinine. Although certain changes in mineral output were clearly attributed to CO2 exposure, the factor of confinement influenced those changes. Author
