In Manesar, the PM2.5 level was recorded at 455, while PM10 was established in 359.
Experts said there had been a large increase at the level of pollutants a day after Diwali.
“Micro climate conditions such as up or down wind movements and temperature variations are responsible for the accumulation of pollutants in one place.
They are responsible for the setback of air quality in hotspots such as Manesar,” Anumite Roychowdhury, Executive Director (Research and Advocacy) at the Center for Science and the environment, to Toi.
Speaking of other hotspots such as Teri Gram, Gwalpahari and Vikas Sadan, he said: “Factors such as firecrackers, burning waste and pollution from burning this stump creating this hotspot.” Experts also emphasize that rupture of crackers intensify the accumulation of PM2.5 in the bottom atmosphere during the curfew, which caused the peak value of PM2.5 across 1,000 μg / m3 sign in most locations.
Smog looks in the morning and bad wind conditions delay dispersion, allowing particles to survive
