Dhaka air quality drops yet again
The quality of air in Bangladesh’s capital city has once again dropped into the “very unhealthy” category. According to the US Air Quality Index (AQI), Dhaka’s air quality index score increased from 185 on Friday to 239 on Saturday, which denotes high  levels of pollution. In real time ranking, Dhaka stood at 3rd place in the international index measured at 9am. The US AQI was developed by the Environmental Protection Agency for reporting daily air quality of any city or country. Kolkata, India topped the list with a score of 264, according to data obtained from AirVisual, a smartphone application that shows real-time air pollution index of cities across the world. Indian capital city of Delhi was in the 2nd position with a score of 244. Dhaka, one of the most populous cities in the world, has long been grappling with air pollution. The city of mosques, as it is called, has continued to rank among the world’s top 10 most polluted cities. The air quality in Dhaka has been declining for years now. It worsens during the dry months – from October to April. Department of Environment Director (air quality management) Md Ziaul Haque said that the quality would gradually improve during the monsoon. Brick kilns, vehicles run by fuels with higher level sulphur, as well as construction works have been identified as major sources of air pollution. In fact, the condition is so serious that five of the top 10 causes of deaths in Bangladesh are related to air pollution, experts say.
