New Delhi:  Air pollution in Delhi continued to choke its residents on Monday with the air quality index (AQI) touching the dangerous 408 mark.

The drop in air quality prompted environment experts to urge the government to issue health advisories.

The AQI of Delhi was second only to Lucknow, whose figure stood at 421, making it the city with the poorest air quality.

“The situation is really very bad and the quality of air in the coming days is going to be the same following the smog and stagnancy in the air,” Vivek Chattopadhyaya of green think tank Centre for Science and Environment (CSE) told reporters.

He urged the government to issue health advisories, as several people will suffer from breathing issues if the air quality remains the same.

The AQI of Delhi’s adjoining areas also remained severe at the 405 mark.

Residents complained of breathing problems due to the poor air quality.

Priyanka Rai, a student of Delhi University who has to travel from west Delhi’s Punjabi Bagh to Delhi University in the north, said, “I have never had breathing problems, but now I feel pain in my chest every time I step out of my house.”

Anjali Mirchandani of the South Delhi Municipal Corporation said, “I, being an asthma patient, have been using a mask every day while travelling to my office. My visits to doctors have increased.”

Delhi hasn’t breathed this clean in years. Rainfall in and around brought the capital’s air quality on Saturday to the “good” condition, while PM 2.5 levels, recorded at 15 by the US Embassy and 17 by Safar, were the lowest in this year.

According to the System of Air Quality and Weather Forecasting (Safar) and the Central Pollution Control Board (CPCB), the overall air quality index (AQI) of Delhi, which was at 47, falling in the good category.

The level of PM2.5 was recorded at 17 and the PM10 level was recorded at 31 on Saturday, Safar said. These denote levels of particulate matter, of two sizes up to 2.5 and 10 micrometres in diameter, in the atmosphere. In comparison, the AQI in New York was recorded at “good” at 17, at 34 in Frankfurt, while in London, it was “moderate” at 52.

A CPCB scientist said that in 2017, the city had witnessed the AQI recorded below 50 – at 42, but could not recall the exact date. The CPCB is recording AQI since 2015 and such good conditions have not been seen in the last four years.

Gufran Baig, scientist and programme director, SAFAR, said that this is the lowest AQI recorded this year and it will remain good for another two to three days. He said that the air quality has improved due to widespread rain received in the northern parts of the country.

“Rajasthan, Himachal Pradesh, Punjab, Haryana and Uttar Pradesh, all areas surrounding are receiving a good amount of rainfall this year which is improving the air condition in the city. Such kind of rain was never received earlier so the air quality has never reached this level,” Baig said.

Mahesh Palawat, Vice President, Meteorology and Climate Change, at private forecaster Skymet Weather told IANS that this was the longest spell of clean air experienced by Delhiites.

“The widespread rain has helped in improving air quality in Delhi as well as in Noida and Gurugram. Increased rainfall activity is likely to bring more respite in coming days,” he said, adding that the rain has helped in settling down pollutants. (IANS)
