At 11 am, Delhi's AQI stood at 483, reports PTI. Weather experts claim pollution levels escalated overnight due to calm winds leading to accumulation of pollutants

The AQI at Pusa, Bawana, Anand Vihar, Ashok Vihar, Mundka, Punjabi Bagh and ITO was between 490 and 500. In the NCR, Noida (487), Ghaziabad (483) and Greater Noida (470), Gurgaon (457), breathed extremely polluted air.

An AQI between 0-50 is considered as 'good', 51-100 as 'satisfactory', 101-200 as 'moderate', 201-300 as 'poor', 301-400 as 'very poor', and 401-500 as 'severe'. Anything above 500 comes under 'severe-plus emergency' category.

As per Skymet, the overall AQI of Delhi had crossed the 600 mark on the index on Saturday night as pollution levels are expected to reduce in the next 24 to 48 hours. Delhi is pinning hopes on meteorological relief with the weatherman saying winds gusting up to 20 to 25 kilometres per hour are likely to prevail in the region from Sunday evening to Tuesday.

The National Captial is likely to get some respite in the coming days as scattered rainfall in Punjab, Haryana, Rajasthan and Delhi is expected on 7 and 8 November due to Cyclone Maha and a fresh western disturbance, Skymet reported. This rainfall, however light, will be significant in terms of reducing the effect of stubble burning and washing away pollutants, weather officials have said.

NASA satellite imagery showed vast swathes of the northern plains, covering Punjab, Haryana, Delhi, Uttar Pradesh, Bihar, and parts of Jharkhand and West Bengal, blanketed under a smoky haze. Apart from the capital, Uttar Pradesh's Ghaziabad and Noida are also reeling under the wave of severe air pollution. In both places, the AQI has crossed the mark of 600. People residing in these areas complained of eye irritation and suffocation due to deteriorating air quality.

"We are athletes and have most of the events in the winter seasons. This thick smog is affecting our health making it difficult to breathe in the poisonous air. The government must do something about it," Prashant Shukla, a local from Ghaziabad, told ANI.

Another local from Ghaziabad, Mukul Sharma, also narrated his ordeal and said, "I am coughing too much these days. I do not know how to safeguard myself from increasing air pollution. The government must tighten the noose around stubble burning."

After Delhi, all government and private schools up till Class 12 in Noida and Greater Noida will remain closed on 4 and 5 November in the wake of a spike in the pollution level, officials aanounced on Sunday. The Gautam Buddh Nagar administration said the decision has been taken as the levels of particulate matter 2.5 and 10 have been excessive in the air since Diwali, resulting in a major dip in the overall air quality.

Authorities in Nodia have also conducted checks at various construction sites and arrested 38 people for flouting the construction ban on Saturday. Thirty-three people were arrested from four sites in Noida by the city magistrate, while one was held by the deputy collector in Dadri. This action has been taken to ensure implementation of the EPCA guidelines and in public interest.

Experts have advised to wear face masks during outdoor exposure and limit outdoor activities to a minimum. Outdoor exercise and ventilation have not recommended against.

On Friday, Environment Pollution (Prevention and Control) Authority declared a public health emergency as the air quality will have an adverse health impact on all particularly the children.

The share of stubble burning in Delhi's pollution stood at 46 per cent on Friday, the highest so far. It dropped to 17 percent on Saturday and is expected to be 12 percent on Sunday, according to the Ministry of Earth Sciences' air quality monitor SAFAR.

To combat the menace of air pollution, chief minister Arvind Kejriwal-led AAP government in Delhi has announced the implementation of the Odd-Even scheme from 4 to 15 November 2019. He has repeatedly said that the smog from the nearby states caused by the burning of crop residue is the major cause of pollution in the region.
