Gazipur is at the top of air pollution among 64 districts in 2021. Last year, the level of harmful particles in the air was recorded at 263.51 micrograms per cubic meter on an average of PM2.5. Besides, Madaripur is among the least polluted cities. The level of PM2.5 in the air of this district was 49.08 micrograms per cubic meter.

Dhaka district has placed (area outside the jurisdiction of city corporation) second place. At the same time, the level of PM2.5 in the air of the Dhaka district was recorded at 252.93 micrograms per cubic meter. Narayanganj is in the third position – where PM2.5  was recorded at 222.45 micrograms per cubic meter. 

This information was given by the Center for Atmospheric Pollution Studies (CAPS) at a program organized at Zahur Hossain Chowdhury Hall at the Jatiya Press Club in the capital on Thursday.

The data of the research conducted on air quality in 64 districts of the country was highlighted in the program. Dr. Ahmed Kamruzzaman Majumdar, Dean of the Faculty of Environmental Sciences at Stamford University and the founder of the campus, presented the information.  

He said the CAPS reviewed the air quality of 64 districts in a scientific manner. The study shows that the average particulate matter in a total of 3,173 places in 64 districts of Bangladesh in 2021 was 102.41 micrograms per cubic meter - which is about 1.57 times (65 micrograms) more than the daily norm.

Besides, the air quality in Gazipur, Dhaka and Narayanganj was 4-5 times more than the standard of Bangladesh. The main causes of air pollution in these districts have been identified as – road excavation and renovation, mega projects, nearby brickfields, thousands of small and large industrial plants, black smoke from unfit vehicles and burning of garbage.  

Presenting the results of the research at the press conference, it was said that Patuakhali and Meherpur are next to Madaripur. The reason for low air pollution in these districts is “abundant vegetation” and “natural reservoirs”. The amount of renovation work in these areas is also less. 

Out of 64 districts, only 10 places have good air quality (below 65 micrograms per cubic meter), the press conference said. The places are – Kurigram (63.33 micrograms), Natore (63.19 micrograms), Joypurhat (58.24 micrograms), Rajbari (58.22 micrograms), Rajshahi (56.41 micrograms), Pabna (56.22 micrograms), Sirajganj (55.2 micrograms), Meherpur (53.36 micrograms), Patuakhali (51.42 micrograms) and Madaripur (49.36 micrograms).
