The AQI, which reports daily air quality, informs residents how clean or polluted the air is and highlights potential health effects. In Bangladesh, the AQI is calculated based on five key pollutants: particulate matter (PM10 and PM2.5), nitrogen dioxide (NO2), carbon monoxide (CO), sulfur dioxide (SO2), and ozone. Dhaka's air quality remains ‘very unhealthy’ Dhaka has long struggled with air pollution. Air quality usually deteriorates in winter and improves during the monsoon season. The World Health Organization (WHO) estimates that air pollution causes about seven million deaths worldwide each year, primarily from stroke, heart disease, chronic obstructive pulmonary disease, lung cancer, and acute respiratory infections.
