Delhi’s Air Quality Turns Severe

Delhi’s air quality deteriorated to a severe category on Saturday as a cover of smog surrounded the national capital and prevented dispersion of pollutants, authorities said. The first time it dipped to the severe category this year was just two days before Diwali.
 
A day after Diwali, which fell on December 7, the air quality again slipped to a severe category on November 8. The third time it slipped into the severe category was on December 12.
 
The overall air quality index (AQI) of the city stood at 408, which falls in the ‘severe’ category, the Central Pollution Control Board (CPCB) data showed.
 
An AQI between 100 to 200 comes under the ‘moderate’ category, 201 and 300 is considered ‘poor’, 301 and 400 ‘very poor’, while that between 401 and 500 is ‘severe’.
