The National Green Tribunal has banned any kind of construction in Delhi/NCR region for the next 7 days owing to high levels of air pollution in the national capital. The order was passed while the NGT was hearing a case relating to the rising pollution levels in the National Capital. The NGT today said that it is banning construction of any type in Delhi for a week. It has also advised all the 5 states to not burn their waste crops and find a solution as soon as possible. Earlier the NGT came down heavily on the governments of Delhi and Punjab for failing to curb pollution. Why are you using cranes to sprinkle water with cranes instead of helicopters, the National Green Tribunal asked the Delhi government.Pulling up the Arvind Kejriwal led Delhi government. “Diwali and crop burning are known factors, did you hold any meeting in August and September to prepare the state to tackle pollution?” the NGT bench asked the government. Doctors urged people to avoid going outdoors unless they wear face masks. There are no official air pollution monitors set up in the Delhi suburban areas, but in both New Delhi and Lucknow, the levels of PM2.5 - tiny particulate matter that can clog lungs - were at least above 400 micrograms per cubic meter on Monday. That's more than 40 times what's considered safe by the World Health Organization, and more than six times the limit set by Indian law.
