The National Green Tribunal on Monday took Delhi government to task, saying no review petition has yet been filed on the Odd-Even policy and asked the government if it was just a media stunt. The AAP government had said that it will on Monday move the NGT asking to exempt two-wheelers and cars driven by women from the plan while implementing the odd-even traffic rationing system in the national capital, even as the pollution in the city worsened on Sunday. The air quality in Delhi had deteriorated on Sunday after a sharp rise in presence of pollutants. Both PM 2.5 and PM 10 levels, measured at 480 and 712 micrograms per cubic meter, respectively, were back at the "emergency" threshold of the Graded Response Action Plan. Experts had earlier forecast a drop in levels from Sunday onwards, but pollution levels rose once again from Saturday evening due fall in temperatures and a drop in the 'boundary layer', which traps pollutants and separates the surface atmosphere with the outer atmosphere.
