Dhaka, the bustling capital of Bangladesh, has recently come in third among the cities with the worst air quality. On a Sunday morning, the Air Quality Index (AQI) hit 228, marking a concerning status for residents.
For context, Lahore in Pakistan and Delhi in India topped the list with AQI scores of 300 and 260. An AQI between 101 and 200 is considered unhealthy for sensitive groups, whereas scores from 201 to 300 are labeled poor. Readings above 300, which fall into the hazardous category, pose serious health risks.
The AQI is a crucial tool used by government agencies to inform citizens about air quality levels. In Bangladesh, it takes into account five major pollutants: Particulate Matter (PM10 and PM2.5), nitrogen dioxide (NO₂), carbon monoxide (CO), sulfur dioxide (SO₂), and ozone.
Air pollution is a persistent issue in Dhaka, often worsening during the winter months and improving slightly during the monsoon. A report from the Department of Environment and the World Bank highlights that major sources of pollution in the city include brick kilns, vehicle emissions, and dust from construction sites.
As winter approaches, the situation tends to deteriorate further, fueled by construction activities and deteriorating road conditions. With air pollution being a top global risk for health issues, its effects are serious. Studies show that exposure to polluted air increases the chances of developing heart disease, respiratory ailments, and even cancer. The World Health Organization estimates that about seven million people died globally in 2019 due to air pollution-related health problems.
Online, reactions to Dhaka’s air pollution have sparked concern among residents. Many share their experiences on social media, exchanging tips for protecting their health, like wearing masks and using air purifiers. This community response reflects a growing awareness of the city’s air quality issues. With more attention being paid to such environmental challenges, residents are urging for stronger regulations and action to tackle air pollution.
