AMBIENT MONITORING STATION (AAQMS)

Ambient air quality criteria or standards are concentrations of pollutants in the air (usually outdoor air but sometimes indoor air) specified for a variety of reasons including for the protection of human health, buildings, crops, vegetation, ecosystems, as well as for planning and other purposes. There is no internationally accepted definition but usually “standards” have some legal or enforcement aspect, whereas “guidelines” may not be backed by laws. “Criteria/criterion” can be used as a generic term to cover standards and guidelines.
