Asphyxiant
Asphyxiant
Asphyxiant (pronunciation: as·phyx·i·ant /əˈsfiksēənt/) is a substance that can cause asphyxia, a condition arising when the body is deprived of oxygen, potentially leading to unconsciousness or death.
Etymology
The term "asphyxiant" is derived from the Greek word "asphyxia," which means "stopping of the pulse." It is combined with the suffix "-ant," which is used in English to form nouns denoting substances that bring about a particular effect.
Types of Asphyxiants
Asphyxiants can be classified into two main categories: simple asphyxiants and chemical asphyxiants.
- Simple asphyxiants are gases that displace or dilute oxygen in the air, making it unavailable for breathing. Examples include nitrogen, helium, methane, and carbon dioxide.
- Chemical asphyxiants are gases that prevent the body from using the oxygen that is breathed in. Examples include carbon monoxide and cyanide.
