PRESENCE OF EXHALED CARBON MONOXIDE IN CONFINED CHAMBERS

Abstract

A study on the contamination of air by exhaled CO oxide in confined rooms is reported. Smokers and nonsmokers were confined in groups of 3 in a testing chamber with a volume of 24 cu m of air for several days. The air-purification system in the chamber was the peroxide type and could only reduce the concentration of CO. Results of the test showed that the nonsmokers exhaled CO at an average rate of 0.016 mg/1 and the smokers, at 0.038 mg/1. After 9 to 10 days the air of the testing chamber with 3 persons contained 0.0230.027 mg/1 of CO. The toxic effect of CO consists (1) in the exchange of the oxyhemoglobin in the blood for carboxyhemoglobin and (2) in the suppression of the redox ferments of living tissues. (Author)
