No major change was recorded in the air quality in areas adjoining Noida’s Sector 93 A after the demolition of the nearly 100-metre-tall Supertech twin towers on Sunday that generated an estimated 80,000 tonnes of debris and sent huge clouds of dust billowing in the air.
The Noida Authority said it closely monitored the air quality index (AQI) and PM10 levels before and after the demolition through 20 monitoring stations.

“The data clearly shows that even after the demolition, the AQI and PM 10 Levels have been within acceptable limits,” it said in a tweet.
Air quality instruments were installed by the Uttar Pradesh Pollution Control Board at six places near the demolition site and air quality information was obtained from them from time to time before and after the demolition, the Noida Authority said in a statement.
Monitoring of air quality was done through the Integrated Traffic Management System installed by the Noida Authority, it said.
“Real-time air quality data is also being received from the instruments. It has been informed by the Uttar Pradesh Pollution Control Board that at 2 PM and 3 PM in the day, the same figures of PM10 and PM2.5 (levels)… have been received,” the Noida Authority said.
The AQI in sectors 91, 125, 62, 1 and 116 stood at 57, 122, 108, 119 and 121, respectively, at 2 pm.
