Dhaka Ranked as the 4th Most Polluted City: Shocking AQI Score Hits 215 – What You Need to Know!

Air pollution is a serious issue in Bangladesh, especially in its capital, Dhaka, which was recently ranked as the world’s fourth most polluted city. On a recent morning, the Air Quality Index (AQI) in Dhaka reached 215. For comparison, Lahore in Pakistan topped the list with an AQI of 338, while Delhi and Kolkata in India followed with scores of 288 and 233, respectively.

The AQI is a tool used to gauge air quality. Scores between 101 and 200 are considered unhealthy for sensitive groups, while AQI readings from 201 to 300 are very unhealthy. A score above 300 is hazardous and poses serious health risks.

In Bangladesh, the AQI reflects levels of five harmful pollutants: Particulate Matter (PM10 and PM2.5), nitrogen dioxide (NO₂), carbon monoxide (CO), sulfur dioxide (SO₂), and ozone. Dhaka often experiences heightened pollution, especially in winter when air quality typically declines. The situation improves during the monsoon season.

A report from the Department of Environment and the World Bank identifies the main culprits of Dhaka’s air pollution: brick kilns, vehicle emissions, and dust from construction sites. These pollutants worsen as winter progresses, leading to increased health risks.

Air pollution is a leading cause of death and disability globally. Research shows that breathing dirty air raises the risk of heart disease, respiratory issues, and even cancer. According to the World Health Organization, around seven million people die each year due to air pollution, with conditions like heart disease, strokes, and respiratory infections being the most affected.

Public reactions to air quality issues have gained momentum on social media, with many people sharing their experiences and urging authorities to take action. Campaigns encouraging cleaner air and healthier cities are becoming more common, reflecting a growing concern among the populace.

Comparatively, in the early 2000s, air quality in Dhaka was not as critically reported, showcasing how rapidly the situation has deteriorated. Today, residents face everyday choices about outdoor activity based on AQI readings, underlining the urgent need for solutions to this environmental crisis.

As cities worldwide grapple with similar challenges, it’s essential for citizens, governments, and organizations to work together to improve air quality for a safer, healthier future.
