Dhaka Struggles with Alarming Air Quality: AQI Hits 167—What You Need to Know

Dhaka, the bustling capital of Bangladesh, recently ranked fourth in the world for poor air quality, with an alarming Air Quality Index (AQI) score of 167. This rating means the air is classified as “unhealthy,” putting residents at risk, especially those with pre-existing health conditions.

For perspective, cities like Lahore, Delhi, and Kolkata top the list with even higher scores of 260, 222, and 174, respectively. The AQI is a key tool that helps us understand how polluted the air is and what health risks come with it. It measures five main pollutants: particulate matter (PM10 and PM2.5), nitrogen dioxide (NO2), carbon monoxide (CO), sulfur dioxide (SO2), and ozone.

When the AQI ranges from 50 to 100, the air quality is deemed “moderate.” But once it crosses 150, the air is classified as “unhealthy,” and for readings between 201 and 300, it’s considered “very unhealthy.” Anything above 301 is “hazardous.” Unfortunately, Dhaka’s air quality frequently suffers, especially in winter months, with slight improvements during the monsoon.

The World Health Organization (WHO) points out the dire consequences of air pollution, estimating it causes around seven million deaths annually worldwide. Most fatalities stem from conditions like stroke, heart disease, lung cancer, and respiratory infections.

Experts emphasize that addressing air quality is crucial. Dr. Shamsul Huda, an environmental health researcher, notes that long-term exposure can lead to serious health issues even in seemingly healthy individuals. He stresses the need for urgent policy changes and community awareness to combat pollution.

Recent social media discussions about the air quality crisis in Dhaka reveal growing concern among residents. Many are urging local authorities to take immediate action, including stricter emissions regulations and promoting green spaces in the city.

The challenges ahead are significant, but understanding the impact of air quality on our health is the first step toward change. As we acknowledge these threats, we also recognize the need for our communities to rally for cleaner air and better health.
