DHAKA, Feb 14, (V7N) - Dhaka, the overcrowded capital of Bangladesh, recorded an Air Quality Index (AQI) of 194 at 9:09 a.m. today, placing it fifth among cities with the worst air quality worldwide.

According to the global air pollution ranking, Pakistan’s Lahore topped the list with an AQI of 309, followed by Cairo (306), Delhi (239), and Kolkata (199). Dhaka’s air was classified as “unhealthy,” posing risks to residents, particularly children, the elderly, and those with respiratory conditions.

An AQI between 151 and 200 is considered “unhealthy,” while 201–300 is “very unhealthy” and 301–400 is “hazardous.” The AQI measures daily air quality based on five pollutants: particulate matter (PM10 and PM2.5), nitrogen dioxide (NO₂), carbon monoxide (CO), sulfur dioxide (SO₂), and ozone.

Dhaka has long struggled with air pollution, especially during winter when dust, brick kiln emissions, and vehicular smoke combine to worsen conditions. Air quality typically improves during the monsoon season due to rainfall that clears pollutants from the atmosphere.

Environmental experts continue to warn that without stricter enforcement of emission controls, improved urban planning, and investment in cleaner energy, Dhaka’s air pollution crisis will persist, threatening public health and quality of life.
