Bangladesh’s capital Dhaka ranked second worst again in the Air Quality Index (AQI) on Tuesday morning for the second consecutive day.
Dhaka had an AQI score of 247 at 08:20am. The air was classified as ‘very unhealthy’.
Israel’s Tel Aviv-Yafo and Thailand’s Chiang Mai occupied the first and third spots in the list of cities with worst air quality with AQI scores of 341 and 199 respectively.
When the AQI value is between 201 and 300, everyone may begin to experience more serious health effects.
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.
In Bangladesh, the AQI is based on five criteria pollutants – Particulate Matter (PM10 and PM2.5), NO2, CO, SO2 and Ozone (O3).
Dhaka has long been grappling with air pollution. Its air quality usually improves during monsoon.
