Centre’s data on stubble burning is misleading: CM

CHIEF MINISTER ARVIND KEJRIWAL SAID NO AGENCY HAD THE SPECIFIC MACHINERY TO MEASURE EITHER THE COMPONENT OR CAUSES OF POLLUTION

NEW DELHI: Delhi chief minister Arvind Kejriwal on Wednesday dismissed a central government weather and air quality service’s claim that stubble burning was responsible for only 10% of the city’s pollution.

The CM said the claim was “misleading” and asserted that no agency had the specific machinery to measure either the component or causes of pollution.

Kejriwal said government agencies should refrain from engaging in “guessing games”.

SAFAR, the union ministry of earth science’s air quality and weather forecast service, had in a recent report said the share of stubble burning in the PM 2.5 concentrations in Delhi was less than 10% so far.

“Agencies claiming little impact of stubble burning should behave more responsibly and sensitively about the figures and data they are sharing,” the CM countered in a statement.

The sources of pollution can only be measured using realtime source apportionment, Kejriwal said.

The CM said his government was trying to import specific machinery to measure real-time source apportionment, which is the only way to ascertain sources of pollution in Delhi.

“If we take a sample of air of this particular place, we can check the level of pollution and also measure the components of pollution like transport, stubble burning,” Kejriwal said.

He added, “How could have local sources contributed to the sudden spike in pollution? There has been no source apportionment of pollution by any of these agencies. These guessing games should be stopped.”

Kejriwal said though Delhi had internal pollutants, these were causing the same amount of pollution as in September and October.

Nothing drastic had happened in the last few days that would result in increased pollution, except stubble burning that started a week back, he said.
