Dhaka’s air quality has turned ‘good,’ all thanks to monsoon showers in different parts of the country.
With an air quality index (AQI) score of 47 at 10:30am today (27 May), the city ranked 67th in the list of world cities with the worst air quality.
India’s Delhi, Pakistan’s Lahore, and the Philippines’ Manila occupied the first three spots on the list, with AQI scores of 195, 173, and 115, respectively.
An AQI between zero and 50 is considered ‘good.’
When the AQI value for particle pollution is 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.
