In a one-year survey, the most contaminated area of Dhaka city rated the Shahbagh area in terms of air pollution. According to a year-long investigation, the average presence of ultra-harmful ultra-fine Particulate Matter 2.5(PM2.5) was 5.8 times greater than the standard.



On the other hand, found the highest noise pollution in the Gulshan-II area. This area’s consistent average noise level was 95.44 decibels, 1.8 times more than normal human endurance.

However, in terms of noise and air pollution, the Parliament building area in Dhaka city was at the bottom.

On June 1, 2022, the Waterkeepers Bangladesh Consortium presented this information at a press conference held at the VIP Lounge of the National Press Club in the capital after years of research.

The average concentration of fine particles PM2.5 per cubic meter of air in those locations was eight micrograms, 5.1 times the annual standard (15 micrograms).

The average concentration of 10 particles in a cubic meter of air was 105 micrograms, 2.1 times higher than the annual standard (50 micrograms on average).



 In terms of air pollution, Shahbagh was the most contaminated area of Dhaka, whereas the National Parliamentary area was the least polluted.

In terms of seasons, Dhaka’s air pollution is worse in the winter. According to the data, the presence of PM2.5 particles in the city was 7.4 times the standard threshold.

 According to the report, the average noise level in the Gulshan-II area was 95.44 decibels, which is 1.8 times more than normal human endurance.
