New Delhi: The national capital witnessed a marginal improvement in air quality on Friday morning, with the Air Quality Index dropping to the ‘poor’ category and averaging 292. However, the relief proved short-lived as pollution levels worsened again by evening, with the AQI rising to 332, placing Delhi back in the ‘very poor’ category, according to official data.
