When the AQI value is between 201 and 300, every city dweller may begin to experience health effects.
Children, adults, and people with respiratory diseases are advised to avoid outdoor exertion while everyone else is suggested to limit outdoor exertion in this situation.
The air quality is categorised as good when the AQI score remains between 0-50. The air is classified as moderate when the score is 51-100. But when the number is between 101 and 150, the air is classified as unhealthy for sensitive groups.
The AQI, an index for reporting daily air quality, tells people how clean or polluted the air of a certain city is, and what associated health effects might be a concern for them.
