Delhi air quality deteriorates to season’s worst, AQI crosses 500

Delhi AQI
NEW DELHI : Air quality in the national capital on Monday, a day after Diwali, was the worst for the season so far, with the air quality index (AQI) at the “severe" mark at 506, according to the Centre-run System of Air Quality Forecasting and Research (SAFAR).
While the PM 2.5 level was at 500+, the PM 10 pollutant indicator stood at 446 – both having breached the “severe" mark on the index, prompting municipal corporation authorities in the city to sprinkle water on roads in several localities.
PM 2.5 are smaller size pollutants which are extremely harmful as they can enter the blood stream, unlike PM10 which only impact the lungs.
An advisory was issued on SAFAR, asking people to avoid outdoor physical activity. People with heart and respiratory diseases have been asked to remain indoors.

According to the SAFAR forecast, the situation on Tuesday will only see a marginal improvement with AQI seen “very poor" at 345, and PM 2.5 and PM 10 levels estimated at 345 and 195 respectively.
Last year, Delhi struggled to breathe as air quality worsened after Diwali, touching “very severe" levels at 642, compelling authorities to step up action. An AQI of above 500 is considered severe and an emergency, as even healthy people can face respiratory problems as well following prolonged exposure to polluted air.
This year, SAFAR's early assessment had shown that air quality after Diwali may not be as bad as last year and will likely remain severe for a shorter period of time unlike what happened in 2018, when poor air quality had persisted for several days.

Meanwhile, the impact of stubble burning incidents is also expected to rise over the next few days, as wind direction changes. The fire count has almost doubled in the past two days, but surface winds prevented accumulation of particulate matter. However, the first week of November is likely to be the worst in terms of air quality, when lack of winds will likely prevent dispersion of air pollutants leading to a spike in pollution.

Delhi's post-Diwali air quality better than last year but worse than 2017

On Diwali, the Delhi AQI was at 999 mark at 11 pm, as per SAFAR.


Delhi's air quality index has dipped to "severe" category a day after Diwali. This is the first time air pollution crossed the 400 mark this season. According to System of Air Quality and Weather Forecasting and Research (SAFAR), the capital recorded the air quality index at 507 on Monday evening. However, the level of pollution is lower than last year. Last year, the overall PM 2.5 level post-Diwali was recorded in the "severe plus emergency" at 642 mark. Nevertheless, the AQI in 2017, 2016 and 2015 on the day after Diwali, was much lower than this year. SAFAR data pointed that the air quality index in 2017 was 367 (very poor), 445 (severe) in 2016 and 360 (very poor) in 2015.
Delhi University North Campus was the worst-hit from the pollution Monday evening. The AQI in North Campus was 740 at around 4:45 pm on Monday. Whereas, in one of Delhi's biggest wholesale market--Chandni Chowk, the AQI touched "severe" category at 677. Both PM 2.5 and PM 10 were at over 500. In area around IIT-Delhi, the AQI was also in "severe" category at 460.
In Noida, the AQI was at 674. However, Gurugram's AQI was in 'very poor' category with 383 overall.
In fight against pollution, the Supreme Court has attempted to restrict the use of crackers this year, forcing the firecracker industry to switch from traditional crackers to green crackers. However, the green pyrotechnics have failed to draw good response both from sellers and buyers, primarily due to lack of variety as well as limited stock and high prices.


On Diwali, the Delhi AQI was at 999 mark at 11 pm, as per SAFAR.

Drastic Increase in Stubble Burning in Punjab & Haryana in 24 Hours, Show NASA Satellite Images

Latest NASA images show a drastic spurt in crop residue burning in the two neighbouring states, which has severely affected Delhi's air quality, the Delhi government said.

New Delhi: Farm fires in Punjab and Haryana increased drastically in the past 24 hours and the share of stubble burning in Delhi's air pollution may touch this year's peak value now, the city government said on Tuesday.

The stubble plume from northwest regions has become one of the significant factors adversely affecting Delhi's air quality, it said in a statement, issued along with NASA satellite imagery and stubble burning-related projections of the Ministry of Earth Sciences' air quality monitor, SAFAR.

Latest NASA images show a drastic spurt in crop residue burning in the two neighbouring states, which has severely affected Delhi's air quality, the Delhi government said.

"The effective stubble fire counts in Haryana and Punjab have increased from 1,654 to 2,577 in the past 24 hours, which is a matter of extreme concern for the residents of Delhi," it said.

The government said the transport-level wind direction was north-westerly on Tuesday, which might increase the share of stubble plume in Delhi's pollution.

"As per SAFAR model, the stubble share may touch this year's peak value now," it said.

Punjab and Haryana have recorded an increase of at least 2,400 farm fires, a major contributor to the air pollution, till October 27, according to government data.

The number of farm fires surged despite the central government issuing strict directions to Haryana and Punjab last week to stop stubble burning completely.

SAFAR on Tuesday predicted that the share of smoke from stubble burning in Delhi's PM 2.5 concentration is likely to jump to 29% on Wednesday. It was 25% on Monday.

Delhi Chief Minister Arvind Kejriwal appealed to Punjab and Haryana to take concrete steps against stubble burning to prevent the national capital from becoming a "gas chamber".

The period between October 15 and November 15 is considered critical as maximum number of stubble burning incidents take place in this span in Punjab and adjoining states.

Despite a ban on stubble burning in Punjab and Haryana, farmers continue to defy it because of lack of financial incentives.

State governments have been providing 50-80 per cent subsidy to farmers and cooperative societies to buy modern farm equipment for in-situ management of paddy straw, and running a massive awareness campaign against stubble burning.

The governments have also been issuing challans against farmers found burning crop residue based on the size of land they own under a 2015 order of the National Green Tribunal.

However, the Punjab and Haryana High Court's September 19 order, staying the recovery of fine from farmers found violating the ban on stubble burning, has subdued the effect of challans, said a Punjab government official.

New Delhi: In the wake of deteriorating air quality in Delhi-NCR post-Diwali festival, health experts have asked residents to take safety precautions to deal with toxic smog and pollutants. There’s clear evidence that exposure to high levels of air pollutants can cause adverse health effects, increasing the risk of cardiovascular disease, asthma and other respiratory diseases, cancer and chronic fatigue. Air pollution has also been linked to a higher risk of diabetes, autism, and lower IQ. Children, pregnant ladies, and the elderly are more susceptible to air pollution.
