New Delhi: The air quality in Delhi on the morning after Diwali was recorded in the 'very poor' category but the situation was relatively better than previous years due to favourable meteorological conditions which prevented rapid accumulation of pollutants. The capital's air quality index (AQI) stood at 326 at 7 am on Tuesday. The neighbouring cities of Ghaziabad (285), Noida (320), Greater Noida (294), Gurugram (315) and Faridabad (310) reported 'poor' to 'very poor' air quality.
An AQI between zero and 50 is considered 'good', 51 and 100 'satisfactory', 101 and 200 'moderate', 201 and 300 'poor', 301 and 400 'very poor', and 401 and 500 'severe'. The relatively better air quality this morning doesn't mean it's good air. The PM2.5 levels at 30 out of 35 monitoring stations in the national capital were five to six times the national standard of 60 microgram per cubic metre at 7 am.
A large number of high-decibel firecrackers thundered throughout Diwali night on Monday as people in Delhi flouted the ban imposed on these by the city government. Delhi Environment Minister Gopal Rai last week said bursting firecrackers in the national capital on Diwali will attract a jail term of up to six months and a fine of Rs 200. Despite the legal deterrent in place, people in many parts of the city, including in south and northwest Delhi, started bursting crackers by dusk. High-intensity firecrackers could be heard going off on the ground or mid-air.
And, as the night progressed the intensity of firecrackers increased breaching permissible decibel limits, prompting some to wonder "if there was any ban at all". Bursting of firecrackers on Diwali is an age-old tradition, but authorities in Delhi said the decision to restrict it was taken after considering environmental concerns and health hazards associated with it.
Delhi's air quality turned "very poor" on Monday amid an increase in stubble burning, bursting of firecrackers and moderately unfavourable meteorological conditions which allowed the accumulation of pollutants. However, the 24-hour average air quality index (AQI) of 312 was still the second-best for Diwali in seven years. The city recorded an AQI of 281 on Diwali in 2018. Earlier in the day, experts feared that if the volume of firecrackers burst goes up again this year, the air quality is likely to dip further.
In case firecrackers are burst like last year, the air quality may plunge to "severe" levels on the night of Diwali itself and continue to remain in the "red" zone for another day, the System of Air Quality and Weather Forecasting and Research (SAFAR) had earlier predicted. Notwithstanding the ban, people burst firecrackers with impunity in various areas, starting around 6 pm. In south Delhi's East of Kailash, and neighbouring places like Nehru Place and Moolchand, firecrackers going off mid-air could be heard in the evening. Some residents burst crackers in their neighbourhood like every year.
In Burari too, many residents burst firecrackers despite widespread dissemination of information about the ban. "They are educated but still doing this, what will children learn from it," said a resident of a colony in Burari. In Laxmi Nagar, Mayur Vihar and Shahdara in east Delhi, the situation was similar. While the intensity in the late evening was lower compared to last year, it rose after 9 pm. "It was as if the slog overs have started," a Laxmi Nagar resident said.
Loud thuds of crackers were also reported in southwest Delhi's Munirka area. Bipasha Ghosh, 19, who came to south Delhi's Kailash Hills area from Kolkata, a few days ago, said, "In my area, it went on past 11 pm. I wonder if there is a ban on bursting firecrackers in Delhi. Also, those doing it are irresponsible and insensitive to the environment and to people who have respiratory problems and other health issues".
Many people complained of itchy skin and a burning sensation in their eyes due to smoke from bursting firecrackers. "I will not step out tomorrow, I know what the air quality will be tomorrow," said Reetu Nandan, a student, who lives in south Delhi. Delhi Environment Minister Rai had earlier said production, storage and sale of firecrackers in the city will be punishable with a fine of up to Rs 5,000 and three years in jail under Section 9B of the Explosives Act. A total of 408 teams had been set up to implement the ban.
The Delhi Police set up 210 teams under assistant commissioners of police, while the revenue department set up 165 teams and the Delhi Pollution Control Committee 33 teams. In neighbouring cities of Gurugram and Faridabad too, many people burst firecrackers. The air quality in Ghaziabad (301), Noida (303), Greater Noida (270), Gurugram (325) and Faridabad (256) was reported in the 'poor to very poor' category on Monday. (with Agency inputs)
