In addition, NAAQS were used to establish the online air quality index (AQI), which communicates to the public whether the relative air quality and air pollution level in a given area is healthy or unhealthy. NAAQS addressed six pollutants that threatened public health: sulfur dioxide, nitrogen dioxide, particulate matter, carbon monoxide, ground-level ozone, and lead. It was created to regulate pollutants that may result, or are anticipated to result, in a decrease in public health and that are included in NAAQS.
