It is produced when carbon (including coal and coke)or carbon-containing fuel (including petroleum hydrocarbons; e.g., gasoline, fuel oil)does not burn completely to carbon dioxide, because of insufficient oxygen. CO is present in the exhaust gases of internal combustion engines and furnaces. It is toxic because it binds to hemoglobin in blood much more strongly than does oxygen and thus interferes with transport of oxygen from lungs to tissues (see hypoxia; respiration).

由于内燃机和各种炉子中的碳或含碳燃料未完全转化为二氧化碳,而在其废气中含有一气化碳。一氧化碳所以有毒性,是因为它比氧更易被红血球所吸收,从而阻碍了氧气从肺部输送到需氧组织。
