Delhi
air pollution: There is no respite from severe air pollution
in Delhi as air quality remained in the "severe" category
on Wednesday morning. The air quality was similar to what it was on
Tuesday, the day it slipped into the "severe" category in
the city and the adjoining areas.
At
6 am, the city's overall air
quality index (AQI) was 422 -- a little worse than Tuesday's AQI
of 414 at 8 pm, according to the Central Pollution Control Board.
An
AQI between 0-50 is considered good, 51-100 satisfactory, 101-200
moderate, 201-300 poor, 301-400 very poor, and 401-500 severe. Above
500 is severe-plus emergency category.
Delhi's
air quality took a hit after Diwali night due to a combination of
firecracker emissions, stubble burning and unfavourable
meteorological conditions.
Since
then, pollution levels have been oscillating between the lower end
and the higher end of the very poor category.
Chief
Minister Arvind Kejriwal on on Tuesday appealed "with folded
hands" to Punjab and Haryana to take concrete steps against
stubble burning to prevent the national capital from becoming a "gas
chamber".
His
statement came after latest NASA images showed a drastic spurt in
crop residue burning in the neighbouring states. The stubble plume
from north-west regions has become one of the significant factors
adversely affecting Delhi's air quality.
