Dhaka’s air quality shows significant improvement
Dhaka’s air quality showed significant improvement on Thursday morning as it ranked 19th worst in the Air Quality Index (AQI).
It had an AQI score of 74 at 08:41 am and its air quality was classified as ‘Moderate’.
Pakistan’s Lahore, India’s Delhi and Kuwait’s Kuwait City occupied the first three spots in the list of cities with the worst air with scores of 164, 160 and 156 respectively.
This has significantly cut down air pollution in Dhaka which regularly ranks among top 10 cities with worst air quality.
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.
In Bangladesh, the AQI is based on five criteria pollutants - Particulate Matter (PM10 and PM2.5), NO2, CO, SO2 and Ozone.
Dhaka has long been grappling with air pollution. Its air quality usually improves during monsoon.
