Dhaka, the capital city, grapples with concerning air quality, ranking as the seventh most polluted city worldwide at 8:46 am on Friday. The Air Quality Index (AQI) recorded a score of 161, falling into the “unhealthy” category. This underscores a broader issue of deteriorating air quality across major Asian cities, with Lahore, Delhi, and Tashkent claiming the top three spots.
An AQI score between 201 and 300 signifies very unhealthy air quality, posing significant health risks, especially for vulnerable groups. Residents are advised to take necessary precautions to mitigate potential adverse health effects.
The AQI, derived from concentrations of major air pollutants such as particulate matter (PM10 and PM2.5), nitrogen dioxide (NO2), carbon monoxide (CO), sulfur dioxide (SO2), and ozone, serves as a vital tool for informing the public about daily air pollution levels and associated health implications.
Dhaka’s persistent struggle with air pollution, particularly exacerbated during winter, underscores the need for sustained efforts to address environmental health challenges. The upcoming monsoon season is expected to bring relative improvements, highlighting the seasonal dynamics of the city’s air quality.
The World Health Organization (WHO) emphasizes the severe global health consequences of air pollution, linking around seven million deaths annually to air quality-related diseases. These include stroke, heart disease, chronic obstructive pulmonary disease, lung cancer, and acute respiratory infections, emphasizing the urgency of addressing air pollution as a critical public health concern.
