The quality of Delhi’s air deteriorated on Tuesday with PM 2.5 levels shooting up on the fifth day of the odd-even car restriction, shows an analysis by The Energy and Resources Institute (Teri).

Teri is collecting data daily from four Delhi Pollution Control Committee (DPCC) monitoring stations and is looking at five other locations for air quality. The air quality data, made available to Hindustan Times, showed that the city’s air was more polluted on Tuesday when compared to Monday.
