This year, Diwali is celebrated with more enthusiasm.
“People are waiting to celebrate and do it with less frightened,” said Priyanka Golecha from Purasawalkam.
The police ordered 668 cases against people to start fireworks outside the restricted time.
“Green crackers will never solve problems because it is only 30% less pollution compared to normal.
We have never seen AQI falling to a worrying level in Chennai.
This will definitely cause more diseases related to the lungs and inhibit the development of children , “said G Sundarrajan, an environmental activist from Poovulagin Nanbargal.
A senior TNPCB official associated high pollution levels due to lack of air / wind movement due to moisture.
Rain on Wednesday night and Thursday morning also forced residents to explode firecrackers in a short time at night Diwali.
Also, more rockets and multi-shot use at night caused more PM releases, the official said.
Given the prohibition of several varieties, more people choose fireworks like that and even then there is an increase in sales as a whole, the shop owner said.
However, on Friday night, AIQ began to improve because of the wind.
“But enough damage has been caused,” Sundarrajan said.
There was a decrease in the number of accidents of fire, death, burns and even the sale of liquor.
47 suffered small burns on Thursday.
It was almost doubled the same during Diwali 2020.
The department of fire and rescue services mobilized at least 10 personnel in each of the main control spaces and received 56 calls like that.
