Dhaka’s air quality has once again deteriorated to an “unhealthy” level, according to global air monitoring agency IQAir. As of 9 a.m. Wednesday (October 8), the city recorded an Air Quality Index (AQI) score of 145, ranking fourth among the world’s most polluted cities. Egypt’s Cairo topped the list with a score of 185, followed by Manama in Bahrain (183) and Kolkata in India (177). Although recent rainfall had temporarily improved air conditions in Dhaka, pollution levels have risen again due to ongoing urban and environmental factors. AQI scores between 151 and 200 are considered “unhealthy,” particularly affecting children, the elderly, and people with respiratory conditions. The World Health Organization (WHO) estimates that around seven million people die globally each year due to air pollution-related diseases, including stroke, heart disease, lung cancer, and chronic respiratory illnesses.
