Dhaka Ranks 6th in World’s Most Polluted Cities with Alarming AQI of 152: What You Need to Know

Dhaka, the bustling capital of Bangladesh, is facing a serious air quality crisis. Recently, it ranked sixth globally for poor air quality, registering an Air Quality Index (AQI) of 152. This “unhealthy” level puts the city in the company of Cairo, Kinshasa, and Kabul, which have even worse scores.

The AQI is crucial for understanding air pollution levels. Scores between 50 and 100 are “moderate.” In contrast, anything above 150 is considered unhealthy, especially for sensitive groups. If the score reaches 300 or more, it’s labeled “hazardous,” posing significant health risks.

What’s driving this pollution? The AQI in Bangladesh is calculated using five main pollutants: particulate matter (PM10 and PM2.5), nitrogen dioxide (NO2), carbon monoxide (CO), sulfur dioxide (SO2), and ozone. Factors like construction dust, vehicle emissions, and industrial waste contribute significantly.

Historically, Dhaka struggles with air quality, especially in winter months. Improvements typically accompany the monsoon season, when rain helps clear the air. In fact, the World Health Organization estimates that air pollution causes around seven million deaths worldwide each year, linked to serious health issues like heart disease and respiratory infections.

User reactions on social media show growing concern about this crisis. Many Dhaka residents express frustration and call for immediate action. They want better policies and practices to combat pollution.

Measures such as increasing green spaces and improving public transport are vital. Experts suggest that these changes could lead to better air quality over time. As we look to the future, tackling air pollution will not only improve health but enhance the quality of life for millions in Dhaka and beyond.
