Delhiites continued to breathe extremely poisonous air on Tuesday as the city's AQI remained in the severe-plus category for the second day running.
Almost all areas in the capital remained well within 'severe' levels throughout the day and experts said there was little hope of a marked improvement in air quality over the next few days.

Delhi's average AQI was 460 on a scale of 0 to 500, just a shade better than the previous day's reading of 494 which was the second-worst air day on record. The thick shroud of smog seen over the city on Monday eased due to the dense fog layer moving east towards west UP
Greater Noida had an AQI of 372 (very poor), Noida 370 (very poor), Gurgaon 402 (severe), Faridabad 320 (very poor) and Ghaziabad 434 (severe).
Immediate relief unlikely, GRAP-IV to stay in force at least until Monday
Delhi's average AQI was 484 at 9 a.m. on Tuesday which had improved to 473 by noon and to 464 by 3 p.m.
According to weather analysts Delhi had seen dense fog on Monday leading to intensive trapping of pollutants as the fog cover persisted for a longer time.
Although the fog moved towards west UP pollution levels may see no significant change due to low wind speed and high moisture in the air. According to the India Meteorological Department (IMD), Safdarjung saw a minimum visibility of 600m while Palam saw 1000
The city saw north-westerly and westerly winds up to 6-8kmph on Tuesday. On Monday the dense fog layer entered the city from Punjab and Haryana which made dispersion difficult. The fog has shifted though the city still saw shallow fog and mist so there is no significant improvement in AQI for now.
The air quality is likely to be in the severe category from November 20 to 22. In the subsequent six days the air quality is likely to be in the severe to very poor category.
PM2.5 levels in the city oscillated between 287.2 and 422.2 micrograms per cubic metre on Tuesday against a 24-hour national standard of 60 micrograms per cubic metre and 15 units for WHO standards.
PM10 levels hovered between 416.8 and 578.6 micrograms per cubic metre against a national standard of 100 units and 45 units as per WHO standards.
Meanwhile Grap 4 measures continue to be in force since Monday with a ban on construction activities barring essential projects. The entry of trucks also continues to be banned except for those carrying essential items.
