The quality of the capital’s air has hardly improved over the past weeks when Dhaka was put under heavy restrictions with the rest of the country to curb the spread of coronavirus, reports UNB.
Dhaka’s air was ranked worst in the Air Quality Index (AQI) on Thursday morning. It had an AQI score of 233 at 8:35m and the air was classified as ‘very unhealthy’.
Bangladesh’s overcrowded capital grapples with polluted air for a long and people expected it to improve, like other parts of the world, after lockdown was imposed across the country in late March.
In this backdrop, the High Court in January this year issued a nine-point directives to improve the air quality.
Air pollution has been one of the biggest concerns for the megacity surrounded by brick kilns, with uncontrolled discharge of dust from construction works and streets filled with vehicles emitting smokes.
In this backdrop, the High Court in January this year issued a nine-point directives to improve the air quality. Environment, forests and climate change minister Md Shahab Uddin told UNB in February that air pollution “should be seen as an important national crisis”.
Dhaka’s score of 233 in the AQI scale means that everyone may begin to experience more serious health effects.
China’s Chengdu followed Dhaka in the list of cities with the worst air quality with a score of 169.
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 of 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's air quality usually improves during monsoon.
