During the testing, Delhi Environment Minister Gopal Rai said that pollution levels in the hotspots are higher than the average AQI in the capital.

"Today's demonstration at Anand Vihar — a known pollution hotspot — aims to address this issue," Mr. Rai said.

"Pollution levels are elevated at 13 hotspots across Delhi, and this pilot project allows us to test drone-based mist spraying in areas where conventional anti-smog guns can't reach," the Minister said.
