Dhaka air quality improves but still unhealthy
The quality of air in Bangladesh’s capital has shown very little improvement compared to Friday as it continued to be classified as “unhealthy” in an international index. In real time ranking, Dhaka stood at 17th place with a score of 154 in the US Air Quality Index (AQI) measured at 10am on Saturday. The AQI was developed by the Environmental Protection Agency for reporting daily air quality of any city or country. China’s Shenyang topped the list with a score of 267, according to data obtained from AirVisual, a smartphone application that shows real-time air pollution index of any city. Pakistan’s Lahore and Nepal’s Kathmandu were placed at second and third positions with individual scores of 262 and 218. 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.
