Nagpur: Still have doubts about crackers being a major polluter? Such is its effect that the city’s air quality worsened by more than two times in just one day of cracker bursting.
According to the real-time air quality monitoring data available with the Central Pollution Control Board (CPCB), the air quality index (AQI) of Nagpur rose to 169 by Thursday evening. Till November 6, the AQI was 75.
AQI is the figure used to represent how polluted the air is. It is calculated based on four major pollutants — Particulate matter, ground level ozone, carbon monoxide and Sulphur dioxide.
CPCB data shows that on the intervening night of Wednesday and Thursday, the air quality index of particulate matter 10 rose to a dangerous 451.
The level of PM 2.5 also saw a rise. From an index of 60 till late evening, it increased to 122 in late night.
Activists attribute the significant increase in pollution to crackers. “The heavy particles, emitted for crackers, increased the PM 10 levels and resulted in deterioration in air quality,” said Surbhi Jaiswal, team lead of Green Vigil Foundation.
