An analysis of data from the Central Pollution Control Board from the Capital’s 40 monitoring stations showed that high pollution levels across the city affected nearly all monitoring locations at least once. It was not confined to brief episodes, and nearly on one out of three days crossed 250 µg/m³ citywide. Also, the most severe mid-December episode drove average PM pollution to six to seven times the nationally permissible standard.
