Air Quality Challenges in Dhaka

Dhaka, the capital city of Bangladesh, has once again registered concerning air quality levels, ranking 11th on a global list of cities with the worst air pollution. With an Air Quality Index (AQI) of 124 this morning, the air quality was deemed 'unhealthy' for sensitive groups, underlining ongoing environmental challenges in the city.

Understanding Air Quality Index (AQI)

The AQI serves as an important indicator of daily air quality, informing residents about potential health risks associated with pollution levels. In Dhaka, today's AQI value of 124 falls within the 'unhealthy' range for sensitive groups, indicating heightened concerns for vulnerable individuals.

**Global Comparison**

Cities like Delhi (India), Kathmandu (Nepal), and Chiang Mai (Thailand) topped the list with significantly higher AQI scores, underscoring broader regional air quality challenges across South Asia.

Pollutants of Concern

The AQI in Bangladesh is calculated based on several pollutants, including particulate matter (PM10 and PM2.5), nitrogen dioxide (NO2), carbon monoxide (CO), sulfur dioxide (SO2), and ozone. These pollutants contribute to the overall air quality index and can pose serious health risks.

Persistent Pollution Issues

Dhaka has a history of air pollution problems, typically worsening in winter and improving during the monsoon season. Addressing air quality concerns requires sustained efforts and strategic interventions to mitigate pollution sources.

Global Health Implications

The World Health Organization (WHO) highlights the severe health impacts of air pollution, attributing millions of premature deaths worldwide to conditions exacerbated by poor air quality. Stroke, heart disease, respiratory illnesses, and cancer are among the leading causes of mortality linked to air pollution exposure.
