Delhi witnessed a slight improvement in air quality on Sunday, with the Air Quality Index (AQI) dropping to 290 at 4 pm, bringing it into the ‘poor’ category after several days of dangerously high pollution levels.
The national capital had been experiencing ‘very poor’ air quality since November 11, with several hourly AQI readings approaching the ‘severe’ threshold and exceeding it on one occasion. The prolonged pollution spell had left large parts of the city covered in a thick haze, particularly in the aftermath of Diwali celebrations.
According to air quality records, Delhi last registered a ‘poor’ AQI on November 10, when the index stood at 299. Earlier, the city recorded an AQI of 261 on November 1.
Although Sunday’s reading indicated a marginal improvement, pollution levels remained unhealthy, with the city’s air quality continuing to pose concerns for residents.
