Dhaka, the bustling capital of Bangladesh, has once again found itself near the top of the list for poor air quality. On a recent Sunday morning, the city recorded an Air Quality Index (AQI) score of 230, marking it as “very unhealthy.” This level indicates a serious risk to health, particularly for vulnerable groups.
To understand what these numbers mean, an AQI score helps classify air quality. Here are the key ranges:
- 50-100: Moderate
- 101-150: Unhealthy for sensitive groups
- 151-200: Unhealthy
- 201-300: Very unhealthy
- 301 and above: Hazardous
For context, cities like Delhi, Cairo, and Karachi have also been grappling with air quality issues, recording even higher AQI scores of 250, 218, and 215, respectively. This isn’t just a local problem; air pollution affects people globally, with the World Health Organization estimating that approximately seven million lives are lost each year due to air-related illnesses, including strokes and respiratory diseases.
In Dhaka, the main pollutants contributing to poor air quality include particulate matter (PM10 and PM2.5), nitrogen dioxide, carbon monoxide, sulfur dioxide, and ozone. With winter often bringing worse pollution, many residents find themselves choosing to stay indoors more frequently during these months.
Social media reactions highlight growing frustration among citizens. Many express concern over health impacts, especially for children and the elderly. A recent survey indicated that around 60% of Dhaka’s residents worry about air quality every day.
Experts suggest that improving public transportation, regulating industrial emissions, and increasing green spaces could help mitigate this crisis. Creating awareness through education is crucial. While Dhaka’s air quality scores might fluctuate throughout the year, the need for systemic change is urgent and necessary for the well-being of all residents.
In this global climate issue, it’s essential to stay informed and take action. Checking local air quality reports can be a small but effective step in protecting our health.
