Air pollution level in Delhi-NCR this winter was lowest for season since 2018: CSE

New Delhi, Mar 6 (PTI) This winter saw the cleanest air in the Delhi-NCR region since large-scale monitoring started in 2018, according to the latest analysis of air pollution levels by the Centre for Science and Environment (CSE).

The concentration of air pollutants in Delhi stood at 160 micrograms per cubic meter for the October-January period, which is the lowest level recorded since wide-scale monitoring started in 2018-19, the leading think tank said in its report.

"The PM2.5 level, computed by averaging monitoring data from 36 Continuous Ambient Air Quality Monitoring Stations (CAAQMS) stations located in the city was 17 per cent lower compared to the seasonal average of 2018-19 winter. Based on the subset of the 10 oldest stations, there is an improvement of almost 20 per cent," the CSE report said.
