Delhi Pollution: '400+ AQI Before Diwali...' Was Damage Done Before Crackers Started Bursting?

Описание: Delhi News: '400+ AQI Before Diwali...' Was Damage Done Before Crackers Started Bursting? | Delhi AQI After Diwali

IITM forecasts Delhi’s AQI could reach 406 by Monday morning. Delhi’s AQI was already 376 before Diwali evening fireworks. Delhi’s AQI rose from 261 to 369 in six days before Diwali. Last year, Delhi’s AQI rose from 296 before Diwali to 351 afterward. Delhi’s Diwali-eve PM2.5 jumped 63% between 7:45 and 10 pm. An IIT Delhi study found fireworks’ impact fell sharply within 12 hours. The same study linked lingering post-Diwali haze to biomass burning. Transport was projected to account for 19% of Delhi’s Diwali-day PM2.5. Stubble burning’s projected share falls from 3.5% on Diwali to 3% Monday. Industry and power plants also contribute to Delhi’s winter pollution. Weak winds trap firecracker smoke and existing pollution near the ground. AQI shows the spike but cannot quantify this year’s firecracker contributed.
