After rain, Dhaka’s air quality has improved. The capital city ranked 58th on the list of cities worldwide with the worst air quality with an AQI score of 59 at 09:15am this morning.
Dhaka’s air was classified as ‘moderate’ on Saturday, according to the air quality index.
Democratic Republic of the Congo’s Kinshasa, United Kingdom’s Birmingham and Algeria’s Algiers occupied the first, second and third spots on the list, with AQI scores of 181, 156 and 155, respectively.
When the AQI value for particle pollution is between 50 and 100, air quality is considered ‘moderate’, between 101 and 150, air quality is considered ‘unhealthy for sensitive groups’, between 150 and 200 is ‘unhealthy’, between 201 and 300 is said to be ‘very unhealthy’, while a reading of 301+ is considered ‘hazardous’, posing serious health risks to residents.
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 AQI in Bangladesh is based on five pollutants: particulate matter (PM10 and PM2.5), NO2, CO, SO2, and ozone.
Dhaka has long been grappling with air pollution issues. Its air quality usually turns unhealthy in winter and improves during the monsoon.
