Dhaka’s air quality was classified as ‘unhealthy for sensitive groups’ at 9.12am today (April 25), according to the ranking published by IQAir.
India’s Delhi (244), China’s Chengdu (164), and Indonesia’s Medan (152) recorded the worst air among cities around the world, according to the IQAir ranking.
The PM2.5 concentration in Dhaka was 8.8 times higher than the WHO annual air quality guideline value.
An AQI ranked between 0-50 means the air quality is good. The score between 51 and 100 means the air quality is moderate. It is categorised as unhealthy for sensitive groups if the score remains between 101 and 150.
When the score ranges between 151 and 200, it is considered unhealthy.
As one of the world’s most densely populated cities, Dhaka has long struggled with poor air quality. The quality deteriorates further during summer and winter but improves slights in monsoon.
