Dhaka's air quality was identified as 'very unhealthy' this morning (November 19, 2024).

With an air quality index (AQI) score of 246 at 08:20 am, Dhaka, the capital city of Bangladesh ranked 2nd on the list of cities around the world with the worst air quality.

India's Delhi, Pakistan's Lahore, and India's Kolkata occupied the first three spots, with AQI scores of 491, 232, and 226, respectively.

When the AQI value for particle pollution is between 101 and 150, air quality is considered 'unhealthy for sensitive groups', between 151 and 200 is 'unhealthy', between 201 and 300 is said to be 'very unhealthy', and a reading of 301+ is considered 'hazardous', posing serious health risks to residents.

Dhaka's 'unhealthy' air quality persists

In Bangladesh, the AQI is based on five criteria pollutants — particulate matter (PM10 and PM2.5), NO2, CO, SO2, and ozone.

Dhaka has long grappled with air pollution issues. Its air quality usually turns unhealthy in the winter and improves during the monsoon.

As per the World Health Organization (WHO), air pollution kills an estimated seven million people worldwide every year, mainly due to increased mortality from stroke, heart disease, chronic obstructive pulmonary disease, lung cancer, and acute respiratory infections.

Dhaka's air is harmful to any person. Today, the three areas in and around Dhaka where the pollution situation is relatively worse are ICDDRB, Becharam Deuri, and Hemayetpur in Savar.

The main component of Dhaka's air pollution is the presence of very fine particulate matter or PM 2.5 in the air. Today, its presence in Dhaka's air is 31 percent higher than the World Health Organization (WHO) standard.
