Dhaka, the bustling capital of Bangladesh, is facing a serious air pollution crisis. Recently, it reached a worrying Air Quality Index (AQI) score of 164, making it the fifth most polluted city globally. This score indicates ‘unhealthy’ air quality, raising alarms about public health.
For context, cities like Delhi, Beijing, and Lahore took the top three spots, with AQI scores of 248, 233, and 186. The AQI helps people understand air quality levels: a score of 50-100 is ‘moderate,’ while anything above 150 is deemed ‘unhealthy.’ Readings above 300 can be extremely hazardous.
Air quality is measured based on five key pollutants: particulate matter (PM10 and PM2.5), nitrogen dioxide (NO2), carbon monoxide (CO), sulfur dioxide (SO2), and ozone. In Dhaka, air quality tends to worsen during the winter months, improving only with the arrival of the monsoon.
Recent studies suggest that air pollution is linked to about seven million deaths globally each year. Many of these deaths are due to heart disease, stroke, and respiratory issues, as noted by the World Health Organization. Experts warn that prolonged exposure to polluted air can lead to severe health consequences, particularly for vulnerable groups like children and the elderly. This emphasizes the urgent need for solutions to combat air pollution.
Social media has also been buzzing with reactions regarding Dhaka’s air quality. Many residents express frustration and concern, sharing tips on how to protect themselves, from wearing masks to installing air purifiers at home. Trends highlight a growing awareness and urgency around improving environmental conditions.
To navigate through this challenge, local authorities and citizens must collaborate. Sustainable practices, stricter regulations on emissions, and widespread community engagement can significantly improve air quality in Dhaka over time.
