Meanwhile, the air quality continued to remain in the 'very poor' category on Wednesday, with overall AQI (Air Quality Index) standing at 362, according to the System of Air Quality and Weather Forecasting And Research (SAFAR).
An AQI within the limit of 0-5 is regarded as good, 51-100 is satisfactory, 101-200 is moderate, 201-300 is very poor and 401-500 is considered severe/ hazardous.

AQI in severe category affects healthy people and badly impacts those with existing diseases.
