A study was performed to investigate the actual condition of carbon monoxide content in expired air and its relations to life-environmental and physical factors from the viewpoint of health of mother and baby, in a series of 277 pregnant women examined between October and December 1971 at the Metropolitan Koishikawa, Mitaka and Hino Health Centers in Tokyo, with the results summarized as follows : 1) Subjects residing in the midtown area were noted to show average CO concentrations in the expired air slightly higher than those previously reported. There were as many as 72 women (26.0 %) with CO concentrations over 10 ppm, amang the subjects from the midtown area. 2) The concentration of CO in expired air was observed to correlate with the CO level in the immediate life-environment of the individual and hence to change even with a slight degree of alteration in environmental CO concentration. The data also indicate that influence of the CO level in air of the area at latge where the individual lives as well cannot be disregarded. 3) Pregnant women with a history of abnormal gestation and/or abnormal delivery were more frequent in the areas with those exhibiting higher CO concentration in expired air, compared to regions with women showing lower CO levels.
