Dhaka ranks worst in Air Quality Index


The capital city of Dhaka has once again ranked worst in the Air Quality Index (AQI).

Dhaka had a score of 194 at 09:20am on Sunday, indicating that the air quality was "unhealthy."

In the index, Delhi of India, Chengdu of China and Kolkata of India occupied the next three slots with a score of 182, 174 and 173 respectively.

When the AQI value is between 151 and 200, every city dweller may begin to experience health effects. Members of sensitive groups may experience more serious health effects in this situation.

The air quality is categorised as good when the AQI score remains between 0-50 while the air is moderate when score is 51-100. 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.

Bangladesh’s overcrowded capital has been grappling with air pollution for a long time. The quality usually improves during monsoon.
