Ambient Air

Definition - What does Ambient Air mean?

Ambient air is atmospheric air in its natural state. It is what we breathe when the atmosphere is not contaminated by airborne pollutants.

The composition of ambient air varies depending on the elevation above sea level as well as human factors such as the level of pollution.

Safeopedia explains Ambient Air

Ambient air typically consists of 78% nitrogen and 21% oxygen. The extra 1% is a combination of carbon, helium, methane, argon and hydrogen. The closer the air is to sea level, the higher the percentage of oxygen.

Human 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.
