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.

We received request; will decide soon whether to support TVK: Thirumavalavan
Chennai (PTI): VCK leader Thol Thirumavalavan on Thursday said that his party received a request from TVK for support and the high-level committee of his party will decide whether to support the Vijay-led party to form the government.
The TVK won 108 seats in the 234-member Assembly and emerged as the single largest party. Vijay will have to resign from one of the two constituencies he has won.
Though the Congress party, which has five MLAs, has extended support to TVK, the actor-politician-led party was still short of as many seats to touch the magic number of 118, the majority mark in the 234-member House.
"We received the request letter from TVK. We are thankful for that. We have not ignored his (Vijay's) request. We have a procedure. Therefore, our party's high-level committee will decide soon. We are going to discuss the merits and demerits of our position," the VCK leader told reporters here.
With regard to the delay in the governor's call to the TVK, which is the single largest party, to form the government, Thirumavalavan requested the governor to invite Vijay to form the government. "It is a constitutional right and people's verdict," he added.
Asserting that the governor cannot say that Vijay should hold 118 MLAs' support now itself to form the government, he said that after taking over power, Vijay has to prove an absolute majority only on the floor of the Assembly.
