[Relationship of the content of carboxyhemoglobin in the blood and of carbon monoxide in the expired air of test subjects to the CO concentration in the air of a hermetic chamber].
Four manned experiments (4 test subjects participating in each) were carried out in a chamber of 24 m3. The effect of CO at a concentration of 10 to 45 mg/m3 on the content of carboxyhemoglobin in the blood, nonhemoglobin iron in the plasma, CO in the breathing air, catalase and peroxidase activity was studied. A correlation was found between these parameters and CO concentration in the atmosphere and exposure time. It was demonstrated that a continuous exposure (up to 90 days) to CO at a concentration of 10 mg/m3 under favorable microclimatic conditions produced no significant effect on the above mentioned biochemical paramters.
