Dhaka Ranks 13th in Global Air Pollution Index with ‘Moderate’ AQI Score

Dhaka Ranks 13th in Global Air Pollution

Dhaka, the capital of Bangladesh, has been positioned as the 13th most polluted city in the world in terms of air quality, with an Air Quality Index (AQI) of 84, according to the latest rankings by IQAir. Although Dhaka is categorised as ‘moderate,’ its PM2.5 concentration is 5.4 times greater than the annual guideline set by the World Health Organisation (WHO).

Delhi, the capital of India, ranked first with a score of 191, followed by Jakarta, the capital of Indonesia, with a score of 159, and Kinshasa, the capital of the Democratic Republic of the Congo, with a score of 146, in terms of having the most severe air pollution. Air Quality Index (AQI) scores ranging from 51 to 100 are classified as moderate, whilst scores falling between 101 and 150 and 151 and 200 are designated as unhealthy for sensitive populations and generally unhealthy, respectively.

Dhaka, being one of the most densely inhabited cities globally, has had persistent challenges with its air quality. This issue is particularly severe throughout the summer and winter seasons but shows minor improvement during the monsoon period. The principal sources of pollution were identified in a 2019 study conducted by the Department of Environment and the World Bank. These sources include vehicular emissions, construction dust, and brick kilns.
