The Central Pollution Control Board (CPCB) on Friday reported that the pollution levels in Delhi are lower compared to the air quality recorded during Diwali in 2016.
The Air Quality Index (AQI) value yesterday was 319, terming it in very poor category; while the AQI last Diwali (October 30) had touched severe level after recording an index value of 431.
AQI level from 0-50 is considered good, 51-100 is satisfactory, 101-200 is moderate, 201-300 is poor, 301-400 is very poor, and 401 and above is severe.
On October 9, the Supreme Court had banned the sale of firecrackers during this Diwali to see effects of its suspension in the light of the severe pollution and smog-like conditions prevalent in Delhi during this period.
