The air quality was deemed "unhealthy for sensitive groups," which poses potential health risks for children, the elderly, and individuals with existing respiratory or heart conditions.
World Air Quality Index:
According to the AQI scale, scores ranging from 101 to 150 are classified as "unhealthy for sensitive groups," while higher scores indicate escalating health risks, moving from "unhealthy" to "hazardous" for readings above 301.
Kampala, the capital of Uganda, had the highest AQI at 158, followed by Manama (Bahrain) at 154 and Dubai (UAE) at 152.
The AQI assesses air pollution based on the concentrations of five major pollutants: PM10, PM2.5, nitrogen dioxide (NO₂), carbon monoxide (CO), sulfur dioxide (SO₂), and ozone. In Bangladesh, particulate matter, particularly fine particles like PM2.5, is the primary factor contributing to poor air quality.
Dhaka, recognized as one of the most densely populated cities worldwide, has faced ongoing challenges with severe air pollution, particularly in winter when dust and emissions build up due to dry conditions. Air quality generally improves during the monsoon season, thanks to increased humidity and rainfall.
The World Health Organization identifies air pollution as a significant global health risk, attributing an estimated seven million premature deaths annually to strokes, heart disease, lung cancer, and respiratory infections.
Health professionals advise sensitive individuals in Dhaka to minimize extended outdoor activities during times of poor air quality and suggest wearing protective masks when necessary.
