Delhi’s Air Pollution Spikes, Severe in Some Regions
New Delhi: The National Capital saw a sudden spike in the air-pollution on Saturday, a day after Dussehra. As stubble-burning stepped up in neighbouring Punjab and Haryana, the combined effects of Dussehra and meteorological reasons such as low winds in Delhi gripped the city in a haze with many regions heading towards ‘severe-plus’ or ‘emergency level’ air quality.
The Air Quality Index (AQI) of Delhi on Saturday was 326 — marked very-poor — against 276 on Friday, at about 4 pm. While Dwarka sub-city turned out to be the most polluted with ‘severe-plus’ air-quality and an average AQI of 405, according to Central Pollution Control Board (CPCB).
Earlier on Friday, Delhi Chief Minister Arvind Kejriwal expressed his disappointment that the Centre along with the state governments of Punjab and Haryana did not do anything to manage stubble. Kejriwal warned that Delhi will turn into a ‘gas chamber’ soon.
The average presence of major pollutant PM2.5 or particle with a diameter less than 2.5mm, also spiked in past 24 hours, mostly credited to a festival where hundreds of Ravana effigies were set ablaze to mark Dussehra and the festival traffic.
The average PM2.5 concentration was 186 units across 48 regions of NCR against 129 units merely 24 hours back. The average PM2.5 across 36 areas of Delhi was 191 units at around 5 pm, against 133 units on Friday.
Dwarka sub-city, where incidents of garbage burning intensified the air-pollution levels, saw 239 units of PM2.5 concentration, about seven times the international safety standards.
The permissible range or PM2.5 is 60 as per national standards and 25 by the international standards. (IANS)
