Passing carbon dioxide over a mixture of sodium peroxide and aluminum or magnesium may explode. Carbonic acid is formed in the presence of moisture. Oxygen deficiency during pregnancy has produced developmental abnormalities in humans and experimental animals. Exposure of female rats to 60,000 ppm carbon dioxide for 24 hours has produced toxic effects to the embryo and fetus in pregnant rats. Toxic effects to the reproductive system have been observed in other mammalian species at simialr concentrations.
Carbon dioxide is the most powerful cerebral vasodilator known.
Inhaling large concentrations causes rapid circulatory insufficiency leading to coma and death. No data given. Only regulated as a hazardous material if shipped by air or water.
