According to officials, the Uttar Pradesh Pollution Control Board (UPPCB) had installed six machines to measure the ambient noise and for this measurement data was taken from the nearest three locations of the twin towers. Three machines were installed at Parsvnath Prestige, Baraat Ghar and City Park. All the three machines were at a distance of about 300-500 meters from the blast site. According to official figures, the ambient noise before the demolition of the towers was recorded at 49.5 decibels at Parsvnath Prestige, 65.9 decibels at Baraat Ghar and 56.6 decibels at City Park.

No significant change was recorded in the air quality in the areas adjoining Sector-93A due to the huge plume of 80,000 tonnes of debris and dust.
According to the Noida authority, the air quality index (AQI) and particulate matter (PM) levels of 10 were closely monitored through 20 monitoring centers before and after the blast. “It is clear from the data that even after the collapse of the tower, the AQI and PM10 levels remained within the estimated limits,” the authority said in a tweet.
