Delhi's air quality remains 'very poor' at 312 despite marginal improvement

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

Although the AQI showed a slight 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 deterioration in air quality continues to pose serious health concerns, especially for children, the elderly and those suffering from respiratory illnesses.

Several parts of the national capital recorded high pollution levels. As per CPCB, Anand Vihar registered an AQI of 379, Ashok Vihar at 333, and Wazirpur at 336. Other hotspots included Punjabi Bagh (338), RK Puram (359), Bawana (323), ITO (331), Chandni Chowk (361) and Dwarka Sector 8 (342), all falling in the 'very poor' category.
