The article presents a standard Air Quality Index (AQI) scale, categorizing air pollution levels based on their potential health impacts. The scale ranges from 0 to over 300, with specific numerical thresholds defining different health advisories.

AQI readings between 0-50 are considered 'Good,' indicating minimal risk. Readings from 51-100 are 'Moderate,' meaning air quality is acceptable, but some pollutants may pose a risk to a very small number of people sensitive to air pollution.

When the AQI reaches 101-150, it is classified as 'Unhealthy for Sensitive Groups.' At this level, members of sensitive groups may experience health effects, while the general public is less likely to be affected. An AQI of 151-200 is deemed 'Unhealthy,' posing a greater risk to everyone.

Readings from 201-300 fall into the 'Very Unhealthy' category, indicating significant health risks. An AQI above 300 is labeled 'Hazardous,' signaling a severe health warning for all individuals.
