The Department of Environment (DoE) has advised people to wear a mask if the air pollution in Dhaka reaches "hazarous" level.

When the Air Quality Index(AQI) value for particle pollution is between 101 and 150, air quality is considered “unhealthy for sensitive groups”, between 150 and 200 is “unhealthy”, between 201 and 300 is said to be “very unhealthy”, while a reading of 301+ is considered “hazardous”, posing serious health risks to residents.

Besides, sick people, children and elderly people have been advised not to go out of the house unnecessarily, said a DoE press release.

Considering the level of air pollution, information regarding air pollution and health risk is being disseminated regularly on the website of the DoE.

In a message published under the title of “Air Pollution Health Protection Advice”, the DoE said if the AQI score in Dhaka exceeds 300, people are advised to wear a mask when they go out.

The alert will be withdrawn if the AQI score falls below 300, it said.

Besides, monitoring data of 16 Continuous Air Quality Monitoring System (CAMS) in other divisional and industrial cities of the country including Dhaka is being disseminated regularly on the website of the Department of Environment through real time automation.

The AQI, an index for reporting daily air quality, informs people how clean or polluted the air of a certain city is and what associated health effects might be a concern for them.

The AQI in Bangladesh is based on five pollutants: particulate matter (PM10 and PM2.5), NO2, CO, SO2, and ozone.

Dhaka has long been grappling with air pollution issues. Its air quality usually turns unhealthy in winter and improves during the monsoon.
