On Sunday morning, Dhaka’s air quality was rated as poor for sensitive populations.
On the list of cities with the worst air quality in the world, Dhaka came in at number eighteen, with an air quality index (AQI) score of 119 at 10am.
The top four cities on the list were Shenyang, China, Lahore, Pakistan, and Delhi and Mumbai in India, with AQI scores of 221, 169, 168, and 165, respectively.
An AQI level of 150–200 is deemed unhealthy, 201–300 is deemed extremely unhealthy, and 301–and above is hazardous, presenting significant health hazards to locals.
Five criterion pollutants are used to calculate the air quality index (AQI) in Bangladesh: particulate matter (PM10 and PM2.5), NO2, CO, SO2, and ozone.
Air pollution has always been a problem in Dhaka. Usually, the winter months bring on unhealthy air quality, which then improves during the monsoon.
Across the globe, air pollution is often ranked as one of the major risk factors for both death and disability.
The World Health Organization (WHO) estimates that air pollution kills seven million people annually globally, mostly due to higher rates of stroke, heart disease, lung cancer, chronic obstructive pulmonary disease, and acute respiratory infections.
