Delhi continued to struggle with `very poor` air quality on Thursday morning, even as there was a slight improvement in pollution levels, with the Air Quality Index (AQI) recorded at 312 around 7 am, according to data issued by the Central Pollution Control Board (CPCB).

Although the AQI showed a marginal improvement compared to Wednesday morning, when it stood at 341, pollution levels across the national capital remained firmly in the `very poor` category. The prolonged decline in air quality continues to pose serious health concerns, especially for children, the elderly and those suffering from respiratory illnesses.
