Delhi NCR Air Quality Index, Fog Alerts LIVE News: Amid mounting concern over toxic air quality in the national capital, the Delhi government has announced a fresh set of steps to rein in pollution in the national capital. Key among them is the implementation of the 'No PUC, No Fuel' rule from Thursday.
Now, only BS-VI compliant vehicles registered outside Delhi will be allowed to enter the city, while restrictions on construction activity and trucks carrying construction material will continue under GRAP norms.
Adding to the crisis, dense fog enveloped Delhi-NCR Thursday morning, reducing visibility to 150 metres at Palam and 200 metres at Safdarjung airports, disrupting road traffic and prompting an orange alert. Weather officials warned foggy conditions may persist in early mornings as winter intensifies.
Against this backdrop of rising concern over toxic air, the Lok Sabha is set to hold a detailed discussion today on the worsening air pollution crisis in Delhi and its adjoining regions. Union Environment Minister Bhupendra Yadav expected to respond in the House.

Written by Dr Lepakshi DasariIran-Israel war: Health experts say exposure to such air can have both short- and long-term consequences.
With the maximum temperature settling at 21.7 degrees Celsius at Safdarjung, 9.6 degrees below normal, Delhi logged its coldest March day since March 8, 2020, when the mercury had dropped to 21.2 degrees Celsius.
The AIIMS-Delhi is set to conduct the AIRCARE study, which plans to study the correlation between particulate matter and how it is causing lung cancer.
Extreme heat can affect how the body regulates temperature, fluids and circulation, making pregnant women more vulnerable to heat-related illnesses.
People in war zones, where they are already under stress, can reduce their health risks by staying indoors in the days after military attacks, if possible. Keeping windows and doors closed can help reduce the amount of polluted ambient air
