Carbon monoxide (CO) is a colorless, odorless, and tasteless gas that is slightly less dense than air. It is produced by the incomplete combustion of carbon-containing fuels such as wood, coal, gasoline, natural gas, and oil.
一氧化碳（CO）是一种无色、无味、无臭的气体，密度略低于空气。它是由含碳燃料的不完全燃烧产生的，如木材、煤、汽油、天然气和石油。
Colorless - it cannot be seen by the naked eye. Odorless - it has no smell. Tasteless - it cannot be detected by taste. Non-irritating - CO does not cause immediate discomfort or irritation.
无色——它无法被肉眼看到。无味——它没有气味。无臭——它无法通过味觉检测。无刺激性——CO不会引起即时的不适或刺激。
When inhaled, carbon monoxide binds with hemoglobin in the blood to form carboxyhemoglobin, which reduces the oxygen-carrying capacity of blood and can lead to poisoning. Symptoms of carbon monoxide poisoning include headaches, dizziness, nausea, confusion, and in severe cases, unconsciousness or death.
当吸入一氧化碳时，它会与血液中的血红蛋白结合，形成碳氧血红蛋白，这减少了血液的携氧能力，可能导致中毒。一氧化碳中毒的症状包括头痛、头晕、恶心、困惑，在严重情况下，可能会导致昏迷或死亡。
Common sources of carbon monoxide include motor vehicle exhaust, gas stoves, fireplaces, space heaters, and industrial processes. It is also produced by wildfires and some natural occurrences such as volcanic eruptions.
常见的一氧化碳来源包括汽车排放、燃气炉、壁炉、取暖器和工业过程。它也由野火和一些自然现象（如火山喷发）产生。
To prevent carbon monoxide poisoning, it is important to ensure proper ventilation in areas where combustion occurs. Installing carbon monoxide detectors in homes and workplaces can provide early warning of elevated CO levels.
为了预防一氧化碳中毒，确保发生燃烧的地方有适当的通风非常重要。在家中和工作场所安装一氧化碳探测器可以提前警示一氧化碳浓度升高。
