Summary:
New Delhi: Delhi remained blanketed by a thick smog for the fourth consecutive day on Friday as unfavourable weather hampered dispersion of pollutants, with improvement in air quality expected only by Sunday. The air quality index in the national capital stood at 463 at 4 pm, with Dwarka Sector 8 being the most-polluted area with an AQI of 495. Most of the air quality monitoring stations recorded an AQI above 450. Neighbouring Faridabad (450), Ghaziabad (475), Greater Noida (445), Gurgaon (461) and Noida (474) too continued to reel under severe air quality. "Drizzle (last night) delayed the recovery and hence, improvement in ar quality is now expected only by November 17," SAFAR said..
