Some of the air pollution parameters studied on Deepavali day were higher compared to normal days, according to Tamil Nadu Pollution Control Board.

Two days

The board had studied air and noise pollution levels in the city on November 5 and 10.

While air pollution was monitored at three locations, noise pollution was studied at two locations. PSG College of Arts and Science (sensitive zone), Ponnaiahrajapuram (residential zone) and Collectorate (mixed zone) were the areas identified for studying air pollution.

According to the studies on November 10, suspended particulate materials were 134 at PSG College, 188 at Collectorate and 259 at Ponnaiahrajapuram as against the normal average of 100.

It was raining in many places on Deepavali day.

Also, several varieties of fancy fireworks were burst on the day.

These would have resulted in atmosphere pollution, according to an official of the board.

Noise pollution levels were studied at near Saibaba Temple junction and at Ponnaiahrajapuarm.

Decibel level

The decibel level was 74.5 at Ponnaiahrajapuram and 66.3 near the Saibaba Temple junction and these levels were higher than the normal levels, added the official.
