Since 3 November, the air quality index (AQI) — a measure of eight pollutants, including fine particulate matter, ozone and sulfur dioxide — in Delhi has remained consistently above 99. Anything above 150 is classified as unhealthy.

自 11 月 3 日以来，德里空气质量指数（AQI）一直保持在 99 以上，该指数对细颗粒物、臭氧和二氧化硫等八种污染物衡量。

Other researchers have suggested that recent efforts to clean up sulfur pollution from ships around the world may be pushing up temperatures slightly, since sulfur dioxide tends to reflect sunlight and cool the planet somewhat.

其他研究人员则表示，近期世界各地在清理船舶带来硫磺污染，一行动可能会略微抬高气温，因为二氧化硫往往会反射阳光，让地球变得凉爽一。

Gases such as sulfur dioxide can react with the atmosphere and create what's called Vog, a hazy air pollutant that can irritate the skin and have respiratory effects.
