The report said that this year's Diwali, which was on November 7, was as polluted as Diwali in 2016. The Central Pollution Control Board (CPCB) report also shows a rise in harmful gases such as Carbon Monoxide (CO), Nitrogen dioxide (NO2) and Sulphur dioxide (SO2).

"Particulate concentrations were slightly higher this Diwali as compared to last Diwali (2017)," said the CPCB report. It, however, adds that since in 2017 Diwali was observed on October 19 as against November 7 this year, the meteorological conditions, which govern the dispersion of pollutants, were different.

"Compared with the average Particulate Matter during November 1 to 7 in 2017 with the same period this year, the city average particulate concentration for Delhi is lower in 2018," the report pointed out.

Apart from fireworks and unfavorable wind speed, stubble burning this year had more effect on Delhi's air quality around Diwali, against last year's celebrations (October 19).

On Diwali, there were a total 4,204 fire incidents compared to 1,702 in 2017.

"Diwali-day data shows that the PM10 and PM2.5 values have increased this year compared to 2017. However, the data are similar to Diwali day of 2016 which was observed on 30th October," said the report.

It added that in 2017, the wind directions on Diwali day were east and southeast while in 2018 it was north-west, which might have added pollutant load from stubble burning.

"Contribution of stubble burning in overall PM2.5 concentration during Diwali this year has been estimated at 10 percent." said the report.

The report found that apart from the Dwarka sub-city, the pollutants PM2.5 and PM10 were high almost everywhere else when compared to 2017. Other pollutants CO, NO2, SO2 varied at different places compared to 2017.

The PM2.5 on Diwali 2017 was 638 and 496 units at Janakpuri and Parivesh Bhawan, while this year, these values were 988 and 900 units respectively.

The CO levels at Dilshad Garden were 983 units in 2016, 1,423 in 2017 and 1,441 in 2018. At Shadipur, the NO2 levels were 58 units in 2017 against 94 in 2018.
