Kolkata: The average air quality of 24 hours is still moderate (AQI: 101-200) on the day of the puja-diwali this year.
However, some sustainable ambient air quality monitoring stations (CAAQMS) with spelling shows aqi swings per hour from being up to poor when people turn on all types of fireworks and crackers.
Environmental activists say Diwali once again marks the threshold of air quality decreases in the city and will be very difficult for recovery before next spring.
Three of the seven CAAQMS showed a sharp decline in air quality since the afternoon with AQI into poor (AQI: 201-300).
Bidhannagar (Salt Lake), Rabindra Bharati University campus on Jalan BT in the northern part of the city and the Jadavpur area in the south shows the air quality deteriorating per hour.
All of these areas have celebrated Chhoti Diwali, The Diwali Eve, with Gusto.
Caaqms in Ballygunge, Fort William, Victoria, and Rabindra Sarobar are savings because they maintain a moderate air quality level and ensure that the average AQI is within moderate limits.
But so the day advanced to the night and the night turned to the night, Aqi from Ballygunge and Fort William also inched close to the ‘poor’ category, leaving the WBPCB official worried.
Crackers burst through continuously between 9pm and 10 nights in New Alipore.
Previously, the local police visited Blok K and made the video cracker explode.
Bad air quality causes breathing uncomfortable for most people in old exposure.
“Because we can’t avoid breathing, we have to take care of air quality.
But people seem to forget it at the Dewali Night.
We continue to receive a number of patients who are worrying with acute breathing pressure after night Diwali.
Many of them illuminate their own fireworks,” said Arup Haldar, a senior senior science.
“The noise is less than the last few years, but the air has been heavy with metal released from exploding fireworks.
I think it’s time for advanced religious leaders to remove dictates to the pleasure that has nothing in Fireworks.
Where the toxic fireworks Lakes this chemical in our ancient traditions? “Environmental Words of Crusader Subhas Datta.
The problem is thermal inversion, which is slowly set.
Thermal inversion reduces vertical wind movements due to lower radiative temperatures on the ground.
If the wind speed runs below 2m / sec, the deployment of pollutants from the lower strata of the atmosphere is slow.
As pollutants accumulate at breathing heights, people face serious health impacts, explain WBPCB scientists.
Naba Dutun, Secretary Sabuj Mancha, who has traveled across the city to monitor violations / compliance, said: “The hot spots known from violations in the city have swung to their old habits by extinguishing firecrackers.
The pollution level will definitely go up and that It will affect everyone.
I am horrified thinking about the patient restored Covid who now has a fragile lung.
