“The pollution level also rose due to the week-long heavy smog in the atmosphere. That coupled with pollution from fire crackers worsened things,” said Rajesh Garia, laboratory in-charge, District Pollution Control Board.
The estimated sale of crackers in the city this Diwali touched Rs. 20 crore.
Figures from the district pollution department show that the average sulphur dioxide content in the air on Diwali was 62.52 mg per cubic metre as against last year’s 27 mg per cubic metre.
