New Delhi Tests Anti-Smog Gun to Combat Air Pollution

Authorities in New Delhi have conducted a trial run of an “anti-smog gun” in one of the Indian capital’s most polluted areas as it looks at ways to combat its annual pollution crisis.

The anti-smog gun is a machine that sprays atomised water into the air and is expected to bring down pollution levels.

The device, shaped like a hair dryer and mounted on a flatbed truck, was tested in the Anand Vihar area of New Delhi.

Delhi Environment Minister Imran Hussain said they will observe the difference in pollution levels, if any, after the trial run.

The anti-smog gun will be rolled out in the streets of New Delhi if it turned out to be successful, Mr Hussain said.

According to a US embassy measure, the level of PM 2.5 — a test of the quantity of solid particles and liquid droplets in the air — stood at 408, which is eight times the upper limit of “good” quality air at 50.

This is an improvement over last week when the pollution levels climbed to 12 times above the recommended limit.

A combination of farmers burning stubble, industrial pollution, vehicle exhaust, dust enveloping northern India, including New Delhi, and wind speeds slowing down every year as winter approaches contribute to the pollution.
