Unmasking Dhaka’s Air Quality: Why an AQI of 195 Means It’s Time to Take Action

Dhaka, Bangladesh’s bustling capital, has been ranked fifth in the world for poor air quality, with an air quality index (AQI) score of 195. This score means the air is “unhealthy,” which poses a significant health risk to everyone, especially vulnerable individuals. The alarming air conditions have persisted for several days, calling for urgent action.

To understand the AQI, it’s important to know how it works. An AQI score between 50 and 100 is “moderate,” meaning most people can breathe easily, but sensitive groups should limit time outdoors. When the score hits 101 to 150, it’s “unhealthy for sensitive groups.” Scores above 150 indicate “unhealthy” air, and anything above 300 is “hazardous.”

For context, cities like Delhi and Kolkata in India, and Lahore in Pakistan have even worse air quality. Delhi’s AQI hit a shocking 537, significantly above Dhaka’s level.

Dhaka’s 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. Unfortunately, air pollution has been a long-standing issue for the city. In winter, the air quality worsens, while it often improves during the rainy season.

According to the World Health Organization, around seven million people die annually from air pollution worldwide. This figure highlights the urgent need for solutions to tackle air quality issues, not just in Dhaka, but globally.

Recent social media trends show growing concern among residents regarding air pollution. Many are sharing tips on protecting themselves, such as wearing masks and using air purifiers at home. Awareness is crucial. The more people understand the risks, the better equipped they are to take action.

Addressing air quality challenges will require collective efforts. Experts emphasize the need for cleaner energy sources, better transportation systems, and stricter regulations on emissions to create a healthier environment for all. By taking these steps, cities like Dhaka could see a turnaround in their air quality, benefiting both current and future generations.
