Dhaka, the bustling capital of Bangladesh, has recently taken the unfortunate spot as the ninth city globally for worst air quality, with an AQI score of 155. This reading, recorded around 9:50 AM on a Monday, signals that the air is ‘unhealthy.’ Residents have been feeling the effects as the city’s air quality has been problematic for several days.
The Air Quality Index (AQI) helps us understand how clean or polluted the air is. When the AQI score reaches 101 to 150, it’s considered ‘unhealthy for sensitive groups,’ and anything above 150 falls into the ‘unhealthy’ category. This can pose serious health risks, especially for vulnerable populations like children and the elderly. In comparison, cities like Delhi, Lahore, and Karachi currently dominate the top of the list with even higher scores—316, 196, and 213, respectively.
This issue isn’t new for Dhaka. The air quality often worsens in winter and improves during the rainy season. The AQI here is measured based on five main pollutants: particulate matter (both PM10 and PM2.5), nitrogen dioxide (NO2), carbon monoxide (CO), sulfur dioxide (SO2), and ozone. A recent report highlighted that during peak pollution months, the rate of respiratory illnesses tends to spike, aligning with on-ground observations from local hospitals.
Moreover, according to the World Health Organization, air pollution leads to roughly seven million deaths every year worldwide. Major health problems like stroke, heart disease, and lung cancer can often be traced back to poor air quality. Experts suggest that immediate actions, such as reducing vehicle emissions and increasing greenery, could help improve Dhaka’s situation.
Social media has also been buzzing about air quality lately. Many residents share daily AQI updates, with hashtags like #DhakaAirQuality trending. Some citizens even engage in awareness campaigns, pushing for governmental action to address these urgent environmental issues.
As awareness grows, it’s crucial that both individuals and authorities tackle this pressing problem together, seeking better air quality not only for Dhaka but for urban centers around the world. Recognizing that clean air is vital for health can lead to positive changes in policy and community behavior.
