Dhaka’s air quality 3rd worst in the world Wednesday morning

With an air quality index (AQI) score of 184 at 9:10 am today, Dhaka ranked 3rd on the list of cities worldwide with the worst air quality.

Pakistan’s Lahore and India’s Delhi occupied the first and second spots, with AQI scores of 226 and 186, respectively.

An AQI between 151 and 200 is considered ‘unhealthy’ while between 201–300 is ‘very unhealthy’, and 301–400 is 'hazardous', posing severe health risks to residents.

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.

The AQI in Bangladesh is based on five pollutants: particulate matter (PM10 and PM2.5), NO2, CO, SO2, and ozone.

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

As per World Health Organization (WHO), air pollution kills an estimated seven million people worldwide every year, reports UNB.
