'Very poor' quality air reigned in Delhi on the second day of 'odd-even', even as authorities released conflicting reports on the impact of the vehicular restrictions on January 1 primarily due to different comparative parameters.

The Delhi government issued a statement saying that level of pollutants showed a "marked decrease" as compared to previous year, while The Energy and Resources Institute said pollution levels were more than December RPT December 31 and "violated" the prescribed limits.

"The 24-hourly averaged concentrations at four locations (Mandir Marg, RK Puram, Punjabi Bagh and Anand Vihar) were observed and PM 10, PM 2.5 and NOx concentrations were found to be 5.4, 5.1, and 1.5 times higher than safe standards respectively yesterday," TERI said.

The government said that PM 2.5 (particulate matters less than 2.5 microns in size) measured in 24 locations across the city ranged between 121-226 micrograms per cubic metre. On an average, PM 2.5 hovered around 250 across the national capital in previous years on the same date, it said.
