Delhi's air quality worst in country, hits 'severe' for first time this season
New Delhi, Nov 13: Delhi recorded the country's worst air quality on Wednesday as it turned 'severe' for the first time this season, with the AQI soaring to 418.
Bihar's Hajipur, with an Air Quality Index (AQI) of 417, had the the second-worst reading in the country, Central Pollution Control Board (CPCB) data showed.
Of Delhi's 36 monitoring stations, 30 reported air quality in the 'severe' category, the CPCB said.
In comparison, the national capital's 24-hour average AQI -- recorded at 4 pm every day -- stood at 334 on Tuesday.
An AQI between zero and 50 is considered 'good', 51 and 100 'satisfactory', 101 and 200 'moderate', 201 and 300 'poor', 301 and 400 'very poor', 401 and 450 'severe' and above 450 'severe plus'.
According to the CPCB data, the city's AQI was in the 'severe' category for three days in January.
On January 14, the AQI was recorded at 447, followed by 409 each on January 24 and 26.
The CPCB said 'severe' AQI affected healthy people and seriously impacted those with existing medical conditions.
The air quality in the national capital had been in the 'very poor' category since it plunged to the level on October 30.
According to the Centre's Decision Support System for Air Quality Management, vehicular emission was the top contributor to Delhi's pollution, with an estimated share of approximately 13.3 per cent.
The other prominent pollutants were PM2.5 and PM10.
PM2.5 and PM10 refer to fine particulate matter in the air, with the numbers indicating their size in micrometres.
PM2.5 are fine particles with a diameter of 2.5 micrometres or less, about the width of a human hair. These are so small that these can penetrate deep into the lungs and even enter the bloodstream, posing significant health risks.
PM10 are coarser particles with a diameter of 10 micrometres or less, about the width of 10 human hairs. While not as concerning as PM2.5, these can still irritate the airways and worsen respiratory problems.
Long-term exposure to these particulate matter can increase the risk of heart disease.

London, Nov 22: A bomb disposal squad deployed as a “precaution” to the South Terminal of Gatwick Airport concluded an investigation into a "security incident" on Friday after making a “suspect package” safe.
The South Terminal of Gatwick Airport, the UK's second busiest airport after Heathrow, which was briefly shut owing to the incident reopened following the incident.
The Gatwick is around 45 km south of London.
Two people detained during the enquiries have since been allowed to continue their journey as the airport was opened.
“Police have concluded their investigation into a report of a suspect package at Gatwick Airport. Officers from the EOD (Explosive Ordnance Disposal) team made the package safe, and the airport has been handed back to its operator,” Sussex Police said in an updated statement.
“Two people detained while enquiries were ongoing have subsequently been allowed to continue their journeys. There will remain an increased police presence in the area to assist with passengers accessing the South Terminal for onward travel,” the statement added.
Earlier on Friday, the incident caused severe disruption at the busy airport’s South Terminal, while the North Terminal of Gatwick Airport remained unaffected.
“Police were called to the South Terminal at Gatwick Airport at 8.20 am on Friday (November 22) following the discovery of a suspected prohibited item in luggage,” a Sussex Police statement said.
“To ensure the safety of the public, staff and other airport users, a security cordon has been put in place whilst the matter is dealt with. As a precaution, an EOD (Explosive Ordnance Disposal) team is being deployed to the airport. This is causing significant disruption and some roads around the South Terminal have been closed. We’d advise the public to avoid the area where possible,” it said.
Footage on social media taken outside the airport showed crowds of frustrated travellers being moved away from the terminal building.
Gatwick said it was working hard to resolve the issue.
“A large part of the South Terminal has been evacuated as a precaution while we continue to investigate a security incident," the airport said in a social media post.
“Passengers will not be able to enter the South Terminal while this is ongoing. The safety and security of our passengers and staff remain our top priority. We are working hard to resolve the issue as quickly as possible.”
Train and bus services that serve the airport were also impacted while the police carried out their inquiries.
In an unrelated incident in south London on Friday morning, the US Embassy area in Nine Elms by the River Thames was the scene of a controlled explosion by Scotland Yard dealing with what they believe may have been a “hoax device”.
“We can confirm the 'loud bang' reported in the area a short time ago was a controlled explosion carried out by officers,” the Metropolitan Police said in a post on X.
“Initial indications are that the item was a hoax device. An investigation will now follow. Some cordons will remain in place for the time being but the majority of the police response will now be stood down,” it added.
