With Delhi recording PM 2.5 levels at nearly 21 times higher than permissible limit on Diwali, the Centre summoned governments of Punjab, Delhi, Haryana, Rajasthan, and Uttar Pradesh over enforcing ban on stubble burning.

The decision comes on the day the Central Pollution Control Board released its report on air quality of Delhi.

The permissible limit for PM 2.5 is 60 micrograms per cubic metre. Pitampura in North Delhi recorded the maximum at 1,238 micrograms per cubic metre on Diwali, which is 20.63 times higher than the permissible limits.

As per the report, PM 2.5 levels on the day of Diwali (30 October) across each of the 11 pollution monitoring centres were anywhere between a staggering 4 times to 12 times of what they were the week before (24 October).

For example, as compared to the previous week, Pitampura recorded 12 times higher PM 2.5 levels, while Parivesh Bhavan Centre in East Delhi recorded 11.4 times higher PM 2.5 levels.

At Janakpuri, PM 2.5 levels were 8.7 times higher and at ITO, PM 2.5 levels were 7.6 times higher.

Similarly, on the day of Diwali PM 10 levels were 1.5-4 times higher as compared to the previous week. For example, PM 10 levels at ITO on Diwali were 4.3 times higher than what they were a week ago.

On this Diwali, as compared to last year, PM 2.5 levels were 2-4.5 times higher and PM 10 levels were 1.5-3 times higher.

The Environment Ministry has attributed the spike in pollution levels to four main factors.

It has been observed that open burning of solid waste in and around Delhi, vehicular emissions in Delhi, dust by the roadside and around construction sites in Delhi, and stubble burning of crop residue in neighbouring states of Delhi are major contributors to pollution in Delhi.

Accordingly, five states — Punjab, Harayna, Delhi, UP and Rajasthan — have been summoned in order to ensure effective enforcement of the ban on stubble burning.

The Ministry of Environment, Forest and Climate Change has summoned the concerned secretaries on 4th November to review the situation and to further deliberate on the strategy to minimise occurrences of open burning in agriculture fields.

Press Statement

It has also been decided that CPCB will direct local bodies in and around Delhi to check open burning of solid waste and strictly enforce rules related to prevention of gaseous emission from construction activities.

CPCB will also instruct public road owning agencies in Delhi to ensure that roadsides are watered periodically to control dust.

Delhi Police, too, will be required to streamline movement of traffic at busy intersections so that pollution due to vehicular emissions is minimised.
