Ambient Air

Definition - What does Ambient Air mean?

Ambient air is atmospheric air in its natural state. It is what we breathe in when the atmosphere is not contaminated by air-borne pollutants. Ambient air is vital to the survival of humans and animals. The composition of ambient air varies depending on the elevation above sea level as well as human factors such as the level of pollution. The ambient air quality, therefore, is directly affected by the activities of people.

Safeopedia explains Ambient Air

Ambient air is typically 78% nitrogen and 21% oxygen. The extra 1% is made up of a combination of carbon, helium, methane, argon and hydrogen. The closer the air is to sea level, the higher the percentage of oxygen. Man's activities, particularly the manufacturing processes and the burning of fossil fuels, has directly impacted the ambient air quality due to the high level of industrial and chemical pollutants that have been released into the atmosphere.
