Dhaka’s air still ‘unhealthy’

Dhaka's air quality continued to be in the 'unhealthy' zone as winter is approaching, reports UNB.

With an air quality index (AQI) score of 181 at 830am today, Dhaka ranked fifth in the list of cities worldwide with the worst air quality.

An AQI between 101 and 200 is considered 'unhealthy', particularly for sensitive groups.

Pakistan’s Lahore, India’s Delhi and Pakistan’s Karachi occupied the first three spots in the list, with AQI scores of 292, 277 and 189, respectively.

An AQI between 201 and 300 is said to be 'poor', while a reading of 301 to 400 is considered 'hazardous', posing serious health risks to residents.

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 issues. Its air quality usually turns unhealthy in winter and improves during the monsoon.
