Diwali 2022: Delhi records ‘poor’ air quality for 8th consecutive day – Details!

Delhi’s air high-quality was recorded in the “bad” class for the eighth consecutive day on Sunday and could flip “significant” on Diwali thanks to emissions from firecrackers and an increase in the share of smoke from stubble burning because of a favourable wind velocity and course.

The capital’s Air High quality Index (AQI) stood at 243 at 10 am. It was 265 at 4 pm on Saturday.

Only 1 (Anand Vihar) of the 35 monitoring stations in the town recorded the air high-quality in the “extremely weak” group.

An AQI involving zero and 50 is regarded “excellent”, 51 and 100 “satisfactory”, 101 and 200 “average”, 201 and 300 “inadequate”, 301 and 400 “quite bad”, and 401 and 500 “severe”.

SAFAR, a forecasting agency less than the Union Ministry of Earth Sciences, reported the air top quality might deteriorate to “pretty weak” concentrations even if no firecrackers are burst.

In case firecrackers are burst like very last year, the air good quality may well plunge to “critical” levels on the night of Diwali itself and keep on to keep on being in the “purple” zone for one more day.

Diwali will be celebrated throughout the place on Monday.

The contribution of stubble burning to Delhi’s PM2.5 air pollution has so significantly remained small (up to 5 per cent) thanks to a slow transportation-degree wind pace.

“Having said that, the transport-level wind course and velocity is probably to turn into pretty favourable from Monday afternoon. It will boost the share of stubble burning in Delhi’s PM2.5 pollution to 15-18 per cent on October 25 and push the air good quality into the ‘severe’ group,” explained Gufran Beig, founder job director, SAFAR.

The share of stubble burning in Delhi’s PM2.5 pollution is very likely to maximize to 8 for every cent on Diwali.

Paddy straw burning accounted for 25 for each cent of Delhi’s PM2.5 pollution on Diwali very last yr.

The share of smoke from farm fires in Delhi’s pollution stood at 32 per cent in 2020 and 19 for every cent in 2019.
