‘Oct-Nov period least polluted in Delhi in eight years’

NEW DELHI: The period from October to November was the least polluted in the last eight years in Delhi and there has been no severe smog episode during the winter season so far, according to green think tank Centre for Science and Environment.

“Diwali in a warmer October, lower incidents of crop fires, pre-emptive action based on pollution forecasting, and favourable meteorological conditions including extended rainfall in October, have all contributed towards bending of the early winter pollution curve,” said Anumita Roychowdhury, executive director, research and advocacy, CSE.

The CSE analysis is based on real-time data available from functional air quality monitoring stations in Delhi-NCR. There are 81 continuous ambient air quality monitoring stations (CAAQMS) spread across the region.
