Pollution check in Delhi NCR after Diwali

On the night of Diwali, the Air Quality Index deteriorated rapidly with every passing hour in the national capital. The AQI was 281 at 7 pm. It rose to 291 at 8 pm and further deteriorated to 294 at 9 pm, 296 at 10 pm.
As per the Centre-run System of Air Quality Forecasting and Research (SAFAR) recorded the overall AQI at 319, which falls in the "very poor" category.
The situation was equally bad in the neighbouring areas of Delhi such as Gurugram, Noida and Ghaziabad, where crackers were burst as usual, raising question marks on the efficacy of the administration in enforcing the apex court's ban.
