The most commonly used air quality index in the UK is the Daily Air Quality Index recommended by the Committee on the Medical Effects of Air Pollutants (COMEAP). [39] This index has ten points, which are further grouped into four bands: low, moderate, high and very high. Each of the bands comes with advice for at-risk groups and the general ...
The EPA says that in this range, air quality is acceptable, but there may be a health risk for some people, such as folks who are "unusually sensitive to air pollution." When the index is between ...
And the subsequent Air Quality Index (AQI) measures the amount of pollution in the air on a 0-500 scale, with the higher number signaling a higher concentration of the following pollutants ...
Urban air quality index (AQI) values are computed by combining or comparing the concentrations of a "basket" of common air pollutants (typically ozone, carbon monoxide, sulfur dioxide, nitrogen oxides, and both fine and coarse particulates) to produce a single number on an easy-to-understand (and often colour-coded) scale.
The Air Quality Index uses colors to indicate the level of risk posed by air quality. “When you see those colors, you can associate that with how much of an effect that air pollution will have ...

The air quality in Malaysia is reported as the API (Air Pollutant Index) or in Malay as IPU (Indeks Pencemaran Udara). Four of the index's pollutant components (i.e., carbon monoxide, ozone, nitrogen dioxide and sulfur dioxide) are reported in ppmv but PM 2.5 particulate matter is reported in μg/m 3.
