排灯节次日德里空气质量恶化：多地AQI突破400达「严重」级，全市均值370属「极差」
新德里 — 排灯节（11月8日）过后的第一个清晨，印度首都德里的空气质量急剧恶化。印度中央污染控制委员会数据显示，11月9日上午9时德里空气质量指数（AQI）为370，属「极差」级别，市内多个监测站突破400、进入「严重」级别。
各站读数中，Burari Crossing 达441，Vivek Vihar 437，德里理工大学站434，Jahangirpuri 与德里大学北校区各433，Rohini 430，Ghazipur 418。路透社报道说，居民无视法院命令燃放烟花爆竹是本轮恶化的直接原因；印度最高法院此前只允许在排灯节周末的限定时间内燃放经认证的低污染「绿色烟花」。按瑞士机构 IQAir 的实时排名，德里周一清晨是全球污染第三重的城市，排第一的巴基斯坦拉合尔 AQI 为563，属危险级别。
德里首都区空气质量管理委员会已在排灯节前的周五启动分级响应行动计划第三阶段措施，包括收紧车辆限制、暂停施工、小学实行混合授课。据《印度斯坦时报》对六个连续监测站的比较，今年排灯节污染是2021年以来第三差的一年，节后凌晨1时结束的那个小时，PM2.5 小时均值分项指数平均达655。

Delhi Air Quality Worsens the Morning After Diwali: AQI Crosses 400 Into the Severe Range at Many Stations, City Average of 370 Rated Very Poor
NEW DELHI — Air quality in India's capital deteriorated sharply on the morning after Diwali, which fell on November 8. Data from the Central Pollution Control Board put Delhi's Air Quality Index at 370 at 9 a.m. on November 9, in the "very poor" category, while many monitoring stations across the city crossed 400 into the "severe" range.
Station readings included 441 at Burari Crossing, 437 at Vivek Vihar, 434 at Delhi Technological University, 433 at both Jahangirpuri and Delhi University's North Campus, 430 at Rohini and 418 at Ghazipur. Reuters reported that residents set off fireworks in violation of court orders; India's Supreme Court had allowed only certified low-polluting "green" firecrackers, during limited hours over the Diwali weekend. On Swiss firm IQAir's live ranking, Delhi was the third-most polluted city in the world on Monday morning, behind Lahore in Pakistan at 563, a hazardous reading.
The Commission for Air Quality Management had invoked Stage III of the Graded Response Action Plan across Delhi-NCR on the Friday before Diwali, bringing stricter vehicle restrictions, a halt to construction and hybrid classes for primary school students. A Hindustan Times comparison of six consistently reporting stations found this year's Diwali pollution was the third worst since 2021, with the peak hourly PM2.5 sub-index averaging 655 in the hour ending at 1 a.m. after the festival.
