Delhi’s air continues to remain ‘very poor’

New Delhi, November 8

The national capital’s air quality remained “very poor” on Friday but no drastic decline is expected in the next three days as strong winds are likely to blow in the region.

The city’s overall air quality index (AQI) read 330 at 4 pm. It decreased to 320 at 8 pm.

Air quality in the satellite towns of Faridabad (337), Ghaziabad (355), Greater Noida (367) and Gurgaon (306) remained “very poor”.

An AQI between 201 and 300 is “poor”, 301-400 “very poor” and 401-500 “severe”. An AQI above 500 falls in the “severe plus” category.

After a brief relief, the city’s air quality plunged to the “very poor” category again because of high humidity due to light rains on Thursday.

“Isolated drizzle, cloudy weather and calm winds prevented boundary layer growth and led to the accumulation of local emissions (on Thursday),” the government’s air quality monitoring and forecasting service SAFAR said.

Delhi experienced “slight secondary particulate formation in the early hours (on Friday) but (it) could not multiply much”.

“The wind direction will change to northwesterly and stubble plume intrusion is expected on Saturday,” SAFAR said.

Meanwhile, Delhi Chief Secretary Vijay Kumar Dev on Friday directed various implementing agencies to check encroachments on major traffic corridors, remove construction and demolition (C&D) waste, and close down polluting industries by November 13.

The directions follow the Supreme Court’s recent orders asking various agencies to control factors contributing to pollution in Delhi such as open dumping of waste, garbage burning, unpaved roads, road dust and traffic congestion. 

In an order to all agencies, the chief secretary also marked the officers responsible for each task.

“In case of non-compliance, the HODs/nodal officers will be held personally responsible,” the order read. - PTI

It's visible killer: UN 

United Nations: India is grappling with a "public health disaster" and the air pollution levels in New Delhi are a "visible killer", said Valentin Foltescu, Senior Programme Management Officer for the UN Environment Programme (UNEP) in India. The global body's children agency called on the governments in South Asia to take urgent action to address the air quality crisis. PTI
