Ambient air quality testing is conducted to determine the gaseous or particulate concentration of air that may be released into the environment or breathed by humans. Dry air in the Earth’s atmosphere comprises a dynamic mixture of gases, primarily nitrogen (~78%) and oxygen (~21%). Smaller volumes of argon (~0.9%) and carbon dioxide (~0.04%) are also present alongside copious trace level gas species and various particulate matter.

Ambient air quality is defined as the quality of air outside and sometimes inside. Ambient air quality standards are limits to concentrations of pollutants in air stated for well being of human, nature, animals, etc. There is no single specified definition of standards resulting, Various organizations use standards which are not often similar. Ambient air quality monitoring is also called as Outdoor Air Quality Testing.

Air quality monitoring is the process of assessment of pollutants present in the atmosphere by their quantity and types as per air quality standards. Air quality monitoring helps us to take action based on pollutants present in atmosphere to improve air quality

Below mentioned are National Ambient or Outdoor air quality standards (NAAQS Standards) which are used in ambient air testing.
