Air quality 'very poor' for 14th consecutive day

Delhi's air quality remained firmly in the "very poor" category for the 14th consecutive day on Tuesday, with the Air Quality Index (AQI) recording a 24-hour average of 334.

The primary culprit behind the city's choking smog was vehicular emissions, which accounted for 15.4 per cent of the pollution load.

Since October 30, when the AQI stood at 307, Delhi's air has consistently fallen in the "very poor" bracket. According to the Air Quality Index scale, an AQI reading between 301 and 400 indicates "very poor" air, while readings above 400 signal "severe" conditions.
