Delhi Recorded Second Cleanest Post-Diwali Day Since 2015 Despite Widespread Fireworks, Spike In Stubble Burning. Here's Why
New Delhi: The air quality in Delhi remained within the "very poor" range on Friday morning despite widespread use of fireworks, and other factors like a spike in the share of stubble burning, and emissions from other local sources due to relatively warm conditions with reasonable wind speed and natural ventilation, according to experts. These factors contributed significantly in improving the air quality in city - which hit severe levels during midnight — to reach moderate levels by the afternoon next day, they said. "The deep calm winter inversion conditions are yet to set in. Despite this, the month of October has also seen more poor and very poor days than previous years, even when the contribution of farm fires has been just around 1-3%, indicating a very high impact of local and regional pollution,” said Anumita Roychowdhury, executive director, Research and Advocacy at the Centre for Science and Environment (CSE), according to Times of India.
