Air Quality Index post-Deepavali last year was 235 and 114 this year

As the citizens celebrated Deepavali by bursting fireworks on Wednesday evening, the air quality in the hours following took a toll as it does every year. However, the air quality index value came down compared to the previous year where the quality until the next day of the festival was found to be “poor”.

This year the quality was “moderate” indicating that the quantum of fireworks burnt was comparatively less.

According to the Air Quality Index (AQI) released by the Central Pollution Control Board, the index value, the average of pollution levels in the city from 4 pm on Wednesday to 4 pm on Thursday was 114 with PM 2.5 being the major pollutant.

Last year, on October 20, the day after Deepavali, the city’s air quality index level was 235 and PM 2.5 was the major pollutant.

Though the order of the Supreme Court to burst crackers only between 8 pm and 10 pm was not followed by many, skyrocketing prices and increased consciousness for environment had caused them to limit the celebrations. On Wednesday during the peak hours between 7 pm and 9 pm too, the level of PM 2.5 as recorded by the Continuous Ambient Air Quality Monitoring System (CAAQMS) on the M.G. Road was around 133 micrograms per cubic meter. It was more than 500 micrograms per cubic meter last year.

Enforcement of order

Shaik Navab John, DCP (L&O II), told The Hindu that no cases were booked for violation of the SC directive.

“A majority of the people stopped bursting fireworks by 9 pm or a little later. We campaigned in all areas asking people to follow the SC orders,” Mr. Navab John said. The majority of the people began to enjoy fireworks even before 7 pm and wound up before 9 pm.”
