Dhaka records moderate air quality Thursday morning

The air quality was classified as 'Moderate', indicating that the air quality is generally acceptable, although unusually sensitive people may experience some health effects, according to the AQI scale.

DR Congo’s Kinshasa topped the list with an AQI score of 239.

Malaysia’s Kuching and Pakistan’s Lahore jointly ranked second, with AQI scores of 194 each.

Dubai of the United Arab Emirates ranked third, with an AQI score of 157.

According to AQI standards, a reading between 101 and 150 is considered 'unhealthy for sensitive groups', while 151 to 200 is classified as 'unhealthy'. A reading between 201 and 300 is considered 'very unhealthy', while levels above 301 are deemed 'hazardous', posing serious health risks.

The AQI provides daily updates on air quality, indicating how clean or polluted the air is and highlighting potential health impacts.

In Bangladesh, the AQI is calculated based on five major 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, with air quality typically deteriorating during winter and improving during the monsoon season.

The World Health Organization estimates that air pollution causes around seven million deaths globally each year, mainly from stroke, heart disease, chronic obstructive pulmonary disease, lung cancer and acute respiratory infections, reports UNB.
