While on Tuesday, the city’s air quality was ‘moderate’ with AQI 198, it crossed 250 on Thursday, and further spiking on Friday.
In fact, Friday was the second most air-polluted day of the month after December 19 when the city’s AQI was recorded at 302.
Interestingly, on Diwali night, when people burst crackers and long traffic jams were witnessed, the city’s AQI was 256, well below Friday’s 273.
The most air-polluted locality of the city was Gomtinagar where AQI crossed the severe levels of 350 in the evening followed by Lalbagh and Indiranagar where the AQI crossed 300.
Environmentalist Prof Venkatesh Dutta said, “Drop in temperatures and fog does not allow pollutants to disperse in the atmosphere and hence the air quality deteriorates. People and the government both should take measures to control air pollution.”
He said that if air pollution levels continue to spike the state capital will also choke in smog and severe air pollution levels as being faced by many other UP districts.
