Delhi pollution level alarming post Diwali, people complain of ‘zero visibility’
A blanket of haze and smog enveloped Delhi on Monday morning after night of Diwali revelry and firecracker burning pushed the city’s air quality to alarming toxic highs.
People commuting to their offices early morning posted photographs of smog-covered lights with accompanying texts complaining of “zero visibility”. Many said the air smelt of charred firecrackers and that it was difficult to breathe.
Pollution peaks in the city during Diwali as a hazardous mix of noxious gases and respirable pollutants hang very close to the surface due to low temperature and near-stagnant wind movement.
At 7:23am, HT’s air quality index showed a reading of a severe 447. Air pollution level is classified as severe if it is between 401 and 500. At Mandir Marg in south Delhi, the index read 492 and it was again 500 at Shadipur in west Delhi.
China declares a ‘red alert’ if air quality plunges to this level. If the alarming pollution levels continue for three consecutive days, China facilitates measures such as shutting down schools and offices, closing down industries and power plants, and road rationing of vehicles.
This came after alarm bells were set off on Sunday evening as air quality in the Capital deteriorated alarmingly on Diwali night. Data from the Hindustan Times air quality map showed that the air quality index had peaked -- touching the maximum limit of 500 -- in almost all monitoring spots in the city.
The Delhi Pollution Control Committee’s real-time ambient air quality data said the PM10 readings went up by over 42 times on Sunday from the national ambiance air quality standard at RK Puram. At 10.55pm, PM10 was recorded at 4,273 µg/m³. PM2.5 also touched an alarming high at 748µg/m³ at 2.30am.
Particulate matters (PM) are tiny particles in the air that cause visibility problems and health hazards.
The permissible level of PM 2.5 is 60µg/m³ while PM10 is 100 µg/m³. Levels beyond that can cause harm to the respiratory system as the ultra fine particulates can embed themselves deep into the lungs and enter the bloodstream.
“Pollution level kaafi sheheron mein high hai. Delhi ke logon ka dhanyavad. Iss baar patakhe kum the...(Pollution level is high in many cities. Thanks to the people of Delhi. Firecrackers were fewer this year,” Delhi health minister Satyendra Jain told ANI.
But people could not stop talking about the ‘airpocalypse’ on Twitter.
The Centre’s System of Air Quality and Weather Forecasting and Research (SAFAR) said pollution during this year’s Diwali was expected to be worse than 2014 and 2015 due to a combination of adverse meteorogical factors such as slow wind speed and moisture in the air, a major hindrance in the dispersion of suspended pollutants.
The city of about 20 million, which ranks among the world’s top cities with foul air on a World Health Organisation list, has been struggling to clean its air that contains a toxic cocktail of dust, smoke and gases from vehicle, factory exhausts and coal-fired power stations.
The condition worsens every autumn and winter as the city, buffeted by farmers burning crop stalks in neighbouring states and atmospheric changes, records higher levels of air pollution.
For the uninitiated, Dhan Mill Compound, a former granary and a cluster of warehouses, has morphed into the city’s modish food, fashion, design and lifestyle destination. Its streets are lined with art cafes, home décor outlets, ateliers, art galleries, pottery studios, dance halls and high-end boutiques, whose facades and interiors are as interesting and experimental as the wares they deal in. Interestingly, all of these fancy establishments are housed in re-purposed warehouse buildings, which still have metal roofs.
According to a Delhi government official, a break-up of the total jobs, including the list of employers and the number of people they hired, will be shared “in a couple of days”. Notably, the government portal was launched by chief minister Arvind Kejriwal on July 27, 2020, to help entry-level and blue-collar job seekers connect with employers at a time when the Covid-19 induced lockdown left many people unemployed.
“Manufactures, and start-ups which are working on alternatives to single-use plastic have to pay more GST for raw material. Hence, the Delhi government will write to the Centre and request a reduction in GST rates,” Delhi environment minister Gopal Rai said.
Safdarjung, Delhi’s base weather station, recorded 0.1mm of rainfall between 8:30am and 5:30pm on Sunday. The Capital recorded 1.9mm of rainfall on Saturday and 117.2mm on Friday, making the monthly total 119.2mm so far. The normal monthly average for July is 210.6mm, said weather experts.
Monsoon elevates Adam Khan’s tomb into an emergency sanctuary for passersby (and dogs) speared by sudden showers. Perched atop a Mehrauli hillock, the monument overlooks the Qutub Minar, which appears totally bechara and defenceless in the heavy rain.
