At the monitoring station at the Jawaharlal Nehru Stadium, the PM10 concentration peaked at 1632 µg/m3 at 2 am, when the 24-hour standard is 100 µg/m3. The level remained over 1000 µg/m3 from 11 pm to 4 am, falling to 467 µg/m3 by 8 am on Monday, going by data from the Delhi Pollution Control Committee (DPCC).
