Subtitle: Non-Toxic Gases
The question of what gases are not poisonous can be a complicated one, as certain gases can be toxic in certain concentrations. Generally speaking, however, some of the more common gases that are not toxic include nitrogen, helium, neon, and argon.
Nitrogen: Nitrogen is the most abundant gas found in Earth's atmosphere, making up 78 percent of the air. It is odorless, colorless, and non-toxic. It is used in a variety of industries, including food production, industrial manufacturing, and medical and scientific research.
Helium: Helium is the second most abundant gas in the Earth's atmosphere, making up about 25 percent of the air. It is also odorless, colorless, non-flammable, and non-toxic. It is used in a variety of applications, including welding, medical research, and even as a lifting gas in balloons.
Neon: Neon is a rare gas found in the atmosphere, making up only 0.0018 percent of the air. It is also odorless, colorless, and non-toxic. It is used in a variety of applications, such as lighting, medical research, and advertising.
Argon: Argon is the third most abundant gas in the Earth's atmosphere, making up about 0.93 percent of the air. It is also odorless, colorless, and non-toxic. It is used in a variety of applications, including welding, medical research, and insulation.
In conclusion, there are several gases that are not toxic, including nitrogen, helium, neon, and argon. While these are the more common gases, it is important to research any gas that is being used in a particular application to ensure that it is not toxic.
