With an AQI of 176 at 8:58 am today, Dhaka has topped the list of cities with the worst air quality in the world for the second day in a row.

'Unhealthy' was the designation given to the air.

An AQI of 151 to 200 is deemed "unhealthy," 200 to 300 is deemed "very unhealthy," and 301 or higher is deemed "hazardous," causing serious health hazards to locals.

With AQI ratings of 163, 158, and 154, respectively, Jakarta, India's Kolkata, and Lahore, Pakistan, held the second, third, and fourth positions on the list.

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.

Particulate matter (PM10 and PM2.5), NO2, CO, SO2, and ozone are the five pollutants that make up Bangladesh's air quality index (AQI).

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.

According to the World Health Organization (WHO), air pollution causes the deaths of an estimated seven million people annually, mostly because it increases mortality from conditions including heart disease, stroke, lung cancer, chronic obstructive pulmonary disease, and acute respiratory infections.
