二氧化碳气体无色、无嗅,略带酸味,比空气重,它本身并无毒性,但空气中二氧化碳含量超过一定范围,就妨碍动物对氧的呼吸。 那么,煤矿井下的二氧化碳是不是也会造成对矿工健康的危害呢?这就要看它的浓度如何了。 Carbon dioxide gas is colorless, odorless, slightly sour, heavier than air, and is itself non-toxic. However, if the content of carbon dioxide in the air exceeds a certain range, it will impede the animal’s breathing of oxygen. So, the coal mine is not also caused by carbon dioxide on the health hazards to the miners do? It depends on how its concentration.
