Dhaka's Air Quality Deteriorates to ‘Very Unhealthy’, Ranks Third Among World's Most Polluted Cities
Pakistan's Lahore ranked first with an AQI of 263, followed by India's Delhi in second place with a score of 232.
Dhaka's air quality deteriorated to the ‘very unhealthy’ category on Sunday morning, with the capital recording an Air Quality Index (AQI) score of 206 at 8:31am.
The reading placed Dhaka third among the world's most polluted cities, according to the AQI rankings. Air quality at this level poses serious health risks, with people of all age groups and health conditions potentially experiencing adverse effects. Even short-term exposure to such pollution can cause health problems.
Pakistan's Lahore topped the list with an AQI score of 263, while India's Delhi ranked second with a reading of 232.
Under the AQI scale, readings between 101 and 150 are considered unhealthy for sensitive groups, while scores ranging from 151 to 200 indicate unhealthy air quality. Levels between 201 and 300 fall into the ‘very unhealthy’ category, while readings above 301 are classified as hazardous, posing severe risks to public health.
The AQI provides a daily assessment of air quality by measuring pollution levels and indicating their potential impact on human health.
In Bangladesh, air quality is monitored based on five major pollutants: particulate matter (PM10 and PM2.5), nitrogen dioxide (NO2), carbon monoxide (CO), sulphur dioxide (SO2) and ozone.
According to the World Health Organization (WHO), air pollution contributes to approximately seven million deaths worldwide every year, primarily due to stroke, heart disease, chronic obstructive pulmonary disease, lung cancer and acute respiratory infections.
