Dhaka has long struggled with air pollution, particularly during the dry winter months, although air quality often improves during the monsoon season due to rainfall. The AQI is a daily index that measures air pollution and its potential impact on human health. It takes into account five major pollutants: particulate matter (PM2.5 and PM10), nitrogen dioxide (NO₂), carbon monoxide (CO), sulphur dioxide (SO₂) and ground-level ozone (O₃). Experts say prolonged exposure to polluted air can cause respiratory illnesses, cardiovascular diseases and other health complications, particularly among children, older adults and people with existing health conditions.
