Thick Faze, Smog Persist In Delhi, Air Quality Slips To 'Hazardous'

"This may be due to the differences in background air quality status in October and November".

The air quality started deteriorating rapidly from 7 pm on Wednesday. As with the annual battle Diwali pollution, few believed any legal edicts will be enforced.

The overall Air Quality Index of Delhi at 8:15 am was recorded at 428. On Friday, the AQI was recorded in the severe category at 426.

A "very poor" AQI translates into spike in respiratory illnesses and if the air quality dips further, the AQI turns "severe", which troubles healthy individuals and seriously affects those with health issues.

After the Diwali festival, levels of airborne PM 10 and PM 2.5 touched 470 and 322 respectively, up from 438 and 180 in 2018, the Central Pollution Control Board said in a bulletin. These indices measure the concentration of tiny poisonous particulate matter.

A report by research group Urban Emissions said close to 50 lakh kg of firecrackers were burnt in Delhi this year, the same amount of firecrackers burnt last year which equated to 1,50,000 kg of mass of PM2.5 (particles in the air with a diameter of less than 2.5 mm).

Despite several restrictions and the two-hour window to burst only "green crackers" ordered by the Supreme Court, the national capital didn't appear to adhere to the 10 pm deadline and continued to light polluting firecrackers till late.

Giving a break up of different areas, the CPCB said in Pritampura, the PM10 and PM2.5 levels was 831 and 990 respectively this year, while last year the PM10 and PM2.5 was recorded at 677 and 690 respectively.

Jalandhar topped the chart of having most polluted air in Punjab with 294 (poor) AQI on Diwali night till the time as Ludhiana, which had topped the chart with very poor AQI last Diwali, Diwali night AQI data was not available till November 8 evening.

On Thursday, the Supreme Court-appointed Environment Protection Authority said it was closely monitoring the situation and if the pollution shows an increasing trend then emergency measures will be imposed in the national capital.

The top court had directed the police to ensure that banned firecrackers were not sold and in case of violation, the station house officer (SHO) of the area would be held responsible.

The areas where the violations were recorded included Mayur Vihar Extension, Lajpat Nagar, Lutyens' Delhi, IP extension, Dwarka and Noida Sector 78.
