The air of Dhaka has been labeled ‘unhealthy’ scoring 190 on Air Quality index (AQI) at 9:30am on Sunday, with the fourth worst position globally.
While Lahore from Pakistan, India’s capital Delhi, Kolkata, the closest distant megacity of Dhaka gained the most awful air quality of this planet with respective AQI scores of 225, 204, and 190.
The AQI index shows the particle pollution of air, and correlated health consequences of a certain area on a daily basis.
A AQI value between 101 and 150 is regarded ‘unhealthy for sensitive groups’, ranging from 150 to 200 is ‘unhealthy’, and from from 201 to 300 is marked as very unhealthy, and a value of 300 and more is labeled as ‘hazardous’ with serious health risks for the inhabitants of that area.
For measuring Bangladesh’s AQI, there are five pollutant elements which are Nitrogen Dioxide (NO2), Carbon Monoxide (CO), Sulfur Dioxide (SO2), Oxone, and Particulate matter (PM10 and PM2.5).
Dhaka has been struggling with air pollution for a long time. The air quality becomes poor in winter and turns back during the monsoon.
Each year air pollution takes life of estimated seven million people globally, according to World Health organization’s data, as the mortality rate increased from stroke, heart disease, chronic obstructive pulmonary disease, lung cancer, and acute respiratory infections
