Delhi-NCR covered in a thick layer of haze. Air quality continues to be very terrible as pollution worsens once more.

Delhi: After maintaining with in “bad” category for the previous two days, Delhi’s air quality moved into the “very poor” category around 6:30 am on Friday with an overall Air Quality Index (AQI) of 303. The Commission for Air Quality Management (CAQM) announced that it will assess the situation today because the air pollution levels in the nation’s capital had decreased over the last few days.

Currently, the AQI is 280 in Dhirpur, 303 at IGI Airport (T3), 337 in Delhi University, 329 in Noida, and 239 in Gurugram, according to statistics from SAFAR. An AQI of 201 to 300 is regarded as “poor,” 301 to 400 as “extremely poor,” and 401 to 500 as “severe.”

Delhi International Airport Limited (DIAL) issued a traveller advisory owing to poor visibility as a heavy blanket of fog covered the capital.

“At the Delhi airport, low visibility protocols are in effect. At this time, all flight operations are regular. The airline in question should be contacted by passengers for the most recent flight information “the warning stated.

According to PTI, the Centre’s air quality council may decide to revoke the limitations that were put in place in Delhi-NCR as part of the third stage of the Graded Response Action Plan (GRAP).

Under the third stage of the GRAP, all construction and demolition work is prohibited in Delhi-NCR, with the exception of necessary projects. In the first week of November, when the air quality was bad, the restrictions were put in place.

PM 2.5 are tiny particles with a diameter of 2.5 microns or less that can penetrate the respiratory system deeply, make it to the lungs, and then enter the bloodstream. An AQI of 400 or more is regarded as “severe,” and it can have an adverse effect on both healthy persons and people who already have medical conditions.

Transport-level winds blow in the troposphere and stratosphere, the lowest two levels of the atmosphere, and they transport farm fire smoke from neighbouring states to the national capital area. In Delhi-NCR, burning leaves and vehicle emissions are the main causes of air pollution.

In Punjab, there were 1,778 farm fires on Wednesday compared to 605 on Tuesday. However, figures from the Indian Agricultural Research Institute and SAFAR show that their contribution to Delhi’s PM2.5 pollution decreased from 9% on Tuesday to 5% on Wednesday.

Under stage 3 of GRAP, BS-III gasoline and BS-IV diesel four-wheelers would continue to be prohibited from driving on Delhi’s roadways.
