Wondering About Air Quality After Diwali? Here’s How You Check It

Wondering About Air Quality After Diwali? Here’s How You Check It

The AQI this year was over twice that of 2017. A "severe plus emergency" level AQI essentially means that even healthy people may suffer from respiratory illnesses on prolonged exposure. According to the SAFAR, the moisture in the air on Wednesday was normal, thus reducing the pollution load slightly.

The court also ruled that firecrackers could only be set off between 8:00 pm and 10:00 pm, but their bangs were still reverberating around city neighbourhoods well after midnight. The Central Pollution Control Board's (CPCB) air quality forecast suggests that air quality will continue at "very poor" levels for the next three days across NCR. Over 250 cases of burn injuries were reported by various hospitals in the national capital this Diwali.

The indices mostly measure the concentration of tiny poisonous particulate matter, or PM 2.5, particles that are less than 2.5 microns in diameter, which can be carried deep into the lungs.

On Friday, levels of particulates 2.5 micrometers or less in diameter, the most harmful to human health, peaked at 845, according to the U.S. embassy website that monitors air quality independently. He said that last year average PM10 was 430µgm/m3 and PM2.5 was 226µgm/m3 whereas this year these are 277µgm/m3 and 126µgm/m3 respectively.

In ITO, PM10 and PM2.5 were recorded at 470 and 322 respectively this year, while last year it was recorded at 438 and 180 respectively. In recent weeks Delhi doctors have reported an increase in the number of patients with respiratory problems due to a rise in pollution levels from burning crop residue, vehicle exhausts and industrial gases.

"Only at Anand Vihar and Punjabi Bagh both daytime and night time noise level declined".


Air quality took a hit this Diwali despite the time restriction on bursting firecrackers, which was flouted in several parts of the city.

The "hazardous" figure is roughly 33 times the World Health Organization safe limit of 25 and health experts advise people to stay indoors or use masks for protection.

In the wake of deteriorating air quality in Delhi, the entry of heavy vehicles into the national capital have been stopped after 11 pm.

The Supreme Court had allowed bursting of crackers from 8 pm to 10 pm on Diwali.

The court had said police should ensure that there was no sale of banned firecrackers and in case of any violation, the station house officer (SHO) of the police station of the area would be held personally liable and this would amount to committing contempt of the court.

The areas where the violations were recorded included Mayur Vihar Extension, Lajpat Nagar, Lutyens' Delhi, IP extension, Dwarka and Noida Sector 78.
