Dhaka, which had an air quality index (AQI) score of 194 at 9:05am on Tuesday, placed the capital in the “unhealthy” category and was ranked second among the cities with the worst air quality in the world.
An AQI of 151 to 200 is considered “unhealthy,” 201 to 300 is “extremely unhealthy,” and 301 to 400 is “dangerous,” all of which pose significant health hazards to locals.
With AQIs of 196 and 191, respectively, Yangon, Burma, and Delhi, India, held the first and third positions.
The AQI in Bangladesh is based on five criterion pollutants: ozone, NO2, CO, SO2, and particulate matter (PM10 and PM2.5).
Air pollution has always been a problem in Dhaka. Winter is often when the air quality deteriorates, and monsoon season is when it gets better.
One of the leading causes of death and disability worldwide continues to be air pollution. Many studies have shown that breathing contaminated air increases a person’s risk of getting heart disease, chronic respiratory conditions, lung infections, and cancer.
