India, Nov. 21 -- Delhi, apart from being touted as 'Dilwalo ka Shahar', is also the hub of power and politics with the lords of policymakers ruling the lives of the rank and file. But, it is also most obnoxiously, the city of hazardous smoggy contamination - at least, this is what the city's latest air quality index has revealed.

Even on Wednesday, the air quality remained in the 'severe' range with toxic pollutants continuing to shroud Delhi in a thick blanket of smog. On Tuesday, the AQI range was in the 500 range or "severe plus".

Consequently, the city has turned into a centre of challenging health issues impacting the lives of all and sundry with ramifications evident in multifarious sectors, especially education.
