With AQI over 400, Delhi-NCR grapples with 'severe' air quality post Diwali
A
thick blanket of haze continued to engulf the national capital on Friday,
experts warned that the air
quality is likely to worsen further as the pollution level entered the
"severe-plus emergency" category, or 11 times the permissible limit,
due to rampant bursting of toxic firecrackers on Diwali,
in violation of a Supreme Court order.
The
Supreme Court's firecracker ban on Diwali was violated with impunity across
Delhi and NCR on Diwali with people bursting crackers till late into the night
leading to a thick haze on Thursday morning and air quality dipping six times
from the normal.
As
a result of smoke from the firecrackers, the overall AQI in Delhi jumped to 422
which falls in the severe category, according to the data by SAFAR.
The
PM2.5 (particles in the air with a diameter of less than 2.5 micrometres) and
PM10 concentrations touched 492 and 618 respectively, both in the severe
category, according to SAFAR data.
An
AQI between 0 and 50 is considered "good", 51 and 100
"satisfactory", 101 and 200 "moderate", 201 and 300
"poor", 301 and 400 "very poor", and 401 and 500
"severe".
