Dhaka’s air ranked ‘moderate' in AQI

Dhaka’s air was categorised as ‘moderate’ on Monday afternoon in the Air Quality Index (AQI) -- a significant improvement after days.

The capital city of Bangladesh had an AQI score of 72 at 12:43pm and ranked 20th among the worst polluted cities in the world.

When the AQI value is between 51 and 100, air quality is acceptable. However, there may be a risk for some people, particularly those who are unusually sensitive to air pollution, reports UNB.

Kuwait City, China’s Chengdu and India’s Delhi occupied the first three spots in the list of cities with worst air quality with AQI scores of 196, 149 and 141 respectively.

The AQI, an index for reporting daily air quality, informs people how clean or polluted the air of a certain city is, and what associated health effects might be a concern for them.

In Bangladesh, the AQI is based on five criteria pollutants – Particulate Matter (PM10 and PM2.5), NO2, CO, SO2, and Ozone (O3).

The megacity has long been grappling with air pollution. Its air quality usually improves during monsoon.
