A bench headed by NGT Chairperson Swatanter Kumar asked the officials of Uttar Pradesh government and the authority to explain the steps they were taking to deal with pollution.
The bench was hearing a plea alleging that despite orders, construction material, hazardous to the health of the locals, was lying in the open.
"You have no respect for human rights. This is disgusting. You have no respect for people. PM10 is over 900.
You are equally bound by our order as you are a part of Delhi-NCR. You are making a mockery of the system," it said.
Showing pictures of debris lying on the roadside, petitioner Amit Gupta sought directions to the concerned authorities to immediately remove the material, use of water sprinklers for suppression of dust.
The plea also sought direction to the Uttar Pradesh Pollution Control Board to establish ambient air quality monitoring at sectors 71 and 74-78.
