Firecracker ban hailed even as Delhi's air turns 'very poor'

Press Trust of India  |  New Delhi 

With the banning the sale of firecrackers in the Delhi-NCR region till after Diwali, can Delhiites breathe a sigh of relief?

Not yet, say experts. The of is saturated with pollutants, and the city's dark clouds would need more than this silver lining.

But experts welcomed the order yesterday, banning the sale of firecrackers in Delhi-National Capital Region (NCR) till October 31 in an effort to check this festival of lights.

Union Environment Minister Harsh Vardhan has urged people to abide by the guidelines and "give green and our environment a chance".

Experts also emphasised the importance on sustained focus in tackling the menace and said firecrackers cause episodic spikes in levels of pollutants.

"It is a welcome move. The of is anyway saturated with pollutants at this time of the season as paddy stubble burning starts and temperature drops. fireworks only compound the problem," Bhure Lal, chairman, Environment (Prevention and Control) Authority (EPCA) said.

Going by the prevailing conditions, wherein the quality is already 'very poor' in many parts of the city, the situation may spiral out of control if firecrackers are set off indiscriminately during Diwali, according to SAFAR.

However, the 24-hour average AQI (quality index) is 'poor', a shade better than 'very poor', it said.

Vardhan, in a series of tweets, said firecrackers cause numerous lung ailments and trigger high blood pressure and anxiety.

"And of course, we must spare a thought for poor birds and animals who spend a terrible evening scared by all the fire & noise," he tweeted.

A "very poor" AQI essentially means that people may suffer from respiratory illness on prolonged exposure to such On further dip in quality, the AQI will turn "severe".

"The would ensure that the levels of pollutants do not reach as high a limit as they did last year around With meteorological conditions not being favourable for dispersing dust and particulate matter in a short interval, the regulation is a step in the right direction," Ajay Mathur, director general of TERI, said.

According to a report on composition of firecrackers prepared by Pune-based Chest Research Foundation, they emit extremely high levels of PM 2.5 over a short period of time with the 'snake tablet' variety producing a peak level of 64,850 ug/m3 (micro grams per cubic metre).

The 24-hour prescribed average of PM 2.5, which are ultra fine pollutants measuring 30 times thinner than a human hair, is 60.

Greenpeace India also welcomed the SC decision, saying the verdict might provide some relief from the episodic spikes in the city in October i.e. during

"However, the levels in north India are multiple times higher than the national standards throughout the winter months, hence we also need to look at a stricter, comprehensive and time-bound action plan to address all sources of across the country," it said in a statement.

A report prepared by the the Central Control Board (CPCB) on the health hazards of chemicals and metals present in firecrackers lists toxic dust and carcinogenic (cancer-causing) compounds.

According to the report, many gaseous pollutants emitted due to bursting of firecrackers remain airborne for days, posing danger to children and unborn babies.

A study by a team of scientists of IIT Kanpur has pointed out that during Diwali, PM levels nearly double from the average level and the organic content of PM increases more than twice.

"It is noteworthy that levels of potassium and barium, main components of firecrackers, can increase by about ten times," it says.
