Dhaka, the bustling capital of Bangladesh, recently ranked eighth among cities with the worst air quality, hitting an Air Quality Index (AQI) score of 173. This level classifies the air as ‘unhealthy,’ meaning it poses significant risks to health.
For context, cities like Cairo, Kampala, Kolkata, and Lahore topped the list with even higher AQI scores: 253, 208, 195, and 193, respectively. The AQI values range from ‘good’ (0-50) to ‘hazardous’ (301+). A score between 150 and 200 indicates ‘unhealthy’ air, which can affect everyone, while levels above 200 are considered ‘very unhealthy.’
The AQI helps people understand how pollution may impact their health based on five major pollutants: particulate matter (PM10 and PM2.5), nitrogen dioxide (NO2), carbon monoxide (CO), sulfur dioxide (SO2), and ozone.
Air pollution is a long-standing issue in Dhaka, often worse in winter and slightly improving during the monsoon season. According to the World Health Organization, approximately seven million people globally die each year due to air pollution-related diseases like heart disease, lung cancer, and respiratory infections.
Recent discussions on social media reveal growing concern among residents about their health and the government’s response to air quality. Many are calling for stronger policies and practical steps to combat pollution.
Experts stress that immediate action is essential. Failing to address air quality could lead to increased health problems in the population. Research shows that cleaner air can significantly reduce premature deaths and healthcare costs. Countries that implemented strict pollution controls saw clearer skies and healthier citizens.

In summary, Dhaka’s air quality issue is urgent. With collective action and awareness, there is hope for a healthier city and community.
