At 8 am on Thursday, the Air Quality Index (AQI) in the capital soared to 315 PM, a hazardous level. Dhaka currently ranks second on the list of cities with the worst air quality, behind Pakistan’s Lahore. The air quality is determined by the concentration of suspended fine dust (particulate matter or PM-10) and ultrafine dust (PM2.5), measured in micrograms per cubic metre (ppm). Dhaka consistently tops the list of cities with polluted air, according to IQAir, an international air quality technology company. Recent IQAir data showed Dhaka’s air fluctuating between ‘unhealthy’, ‘very unhealthy’, and ‘hazardous’ levels over the past three days.
