Dhaka claimed the undesirable title of the city with the most appalling air quality worldwide, registering an AQI of 394 On Sunday, February 18th, at 8:24 am.

Classified as "very unhealthy" by the air quality index, the city's air quality woes stem from a blend of five pollutants: particulate matter (PM10 and PM2.5), NO2, CO, SO2, and ozone.

Dhaka's battle with air pollution is longstanding, typically worsening during winter and showing slight improvement during the monsoon season.

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

The cities of Delhi and Mumbai in India, along with Bishkek in Kyrgyzstan, as well as Kolkata in India, clinched the second, third, fourth, and fifth positions respectively on the rankings, boasting AQI scores of 247, 233, 192, 187, and 188.

An accumulation of pollutants measuring between 151 to 200 on the Air Quality Index is deemed as "harmful," with levels escalating to 201-300 described as "highly damaging," and concentrations surpassing 301 characterized as "dangerous," posing substantial health risks to individuals living in the vicinity.

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 World Health Organization (WHO) estimates that air pollution kills seven million people annually globally, mostly as a result of higher mortality rates from heart disease, stroke, lung cancer, chronic obstructive pulmonary disease, and acute respiratory infections.
