Wednesday Morning Air Quality in Dhaka: Unhealthy Conditions for Sensitive Groups

Dhaka, the bustling capital of Bangladesh, is facing serious air quality issues. Recently, it ranked fourteenth on a list of cities with the worst air quality, posting an Air Quality Index (AQI) score of 118. This level is classified as "unhealthy for sensitive groups," which means it poses a health risk, especially to those with pre-existing conditions.

Air quality valuations fall into various categories. An AQI score between 50 and 100 is called "moderate," suggesting that most people can breathe without worry. However, when the score hits between 101 and 150, it’s considered "unhealthy for sensitive groups"—meaning children, older adults, and those with health issues need to be cautious. Higher scores indicate more severe health risks: 151-200 is "unhealthy," 201-300 is "very unhealthy," and scores above 301 are deemed "hazardous."

For context, other cities like Delhi, Kathmandu, and Baghdad topped the list with even worse scores—398, 238, and 192, respectively. This highlights a growing global concern about air pollution. According to the World Health Organization (WHO), air pollution is responsible for approximately seven million deaths globally each year. It significantly contributes to diseases like stroke, heart disease, and severe respiratory ailments.

In Bangladesh, the AQI measures five main pollutants: particulate matter (PM10 and PM2.5), nitrogen dioxide (NO2), carbon monoxide (CO), sulfur dioxide (SO2), and ozone. The situation in Dhaka tends to worsen during the winter months, while air quality improves in the monsoon season when rainfall helps clear the air.

Given the persistent air quality challenges, experts recommend that improving public transportation and implementing stricter emission regulations are crucial steps for cities like Dhaka. By addressing pollution at its source, cities can safeguard the health of their populations and promote a cleaner environment.

Social media reactions and community discussions are growing around this issue. Many residents are expressing their concern online, sharing tips on how to cope during poor air quality days, such as wearing masks or using air purifiers at home.

In conclusion, air pollution is not just a local issue; it’s a global crisis that requires collective effort. With ongoing awareness and action, cities can work towards cleaner air for everyone.
