Bashundhara area scored the worst within Dhaka, with an AQI score of 272.

Bangladesh’s capital Dhaka has ranked second among cities with the worst air quality, despite rain.

It had an Air Quality Index (AQI) score of 212 at 11am on Tuesday, as reported by Air Visuals. The air was classified as " very unhealthy."

Air quality in different parts of Dhaka, including upscale residential areas such as Gulshan and Baridhara, have been experiencing “very unhealthy” air quality over quite a long time.

According to Air Visuals, air quality in Bashundhara, Gulshan, and Baridhara areas had scores of 272, 255, and 212, respectively. The air was classified as "very unhealthy."

India's Delhi, and Pakistan's Lahore occupied the first and third spots in the list of cities with the worst air quality with AQI scores of 239, and 207 respectively.

When the AQI value is between 201 and 300, a city dweller is more likely to be affected and people with respiratory diseases are advised to limit outdoor activities.

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 Department of Environment has also set national ambient air quality standards for these pollutants. These standards aim to protect against adverse human health impacts.

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