Rob Guzman and his husband fled their guest-house rental business just 10 km from the lava flow. They were worried about the ground shaking from the eruptions, clouds of sulfur dioxide gas and roads being closed.

罗布·古斯曼和他丈夫辞去了距离熔岩流仅10公里宾馆租赁业务。他们担心火山爆发时，地面发生摇晃，以及中二氧化硫有毒体，以及道路闭。

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，德里质量指数（AQI）一直保持在 99 以上，该指数是对细颗粒物、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，这一行动可能略微抬高温，因为二氧化硫往往反射阳光，让地球变得凉爽一些。

Yes, the sulfur dioxide mixed with water and oxygen in the atmosphere to become sulfuric acid which is a major contributor to ozone reduction.

是，二氧化硫与大中水和氧混合成为硫酸，这是臭氧减少主要原因。

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.

像二氧化硫这样体与大发生反应并产生所谓“Vog（火山雾）”，这是一种雾蒙蒙污染物，刺激皮肤并影响呼吸。

The readings of PM2.5, PM10, nitrogen dioxide and sulfur dioxide were all at their lowest levels for the same five-month period since records began in 2013.

PM2.5、PM10、二氧化氮和二氧化硫读数都是 2013 年有记录以来同一时期最低水平。

The team found that electric power plants -- which release sulfur dioxide -- were the biggest contributor to deaths related to pollution from other states.

研究小组发现，释放二氧化硫发电厂是造成其他州与污染相关死亡最大原因。

Smoke from peatland wildfires contains a number of hazardous components, including carbon monoxide and sulfur dioxide, other gases, and particles of various sizes.

泥炭地野火产生烟雾含有多种有害成分，包括一氧化碳、二氧化硫以及其它体，还有各种大小颗粒。

These gases are a death filled cocktail of hydrochloric acid, hydrogen, hydrogen sulfide, and sulfur dioxide.

这些体是由盐酸、氢、硫化氢和二氧化硫混合而成致命混合物。

You know, breathing high concentrations here of sulfur dioxide, carbon dioxide and methane gas, in unequal quantities -- 19 years of this.

你知道，呼吸这里高浓度二氧化硫、二氧化碳、和甲烷体，这些不等量体－19年都是如此。

And when it is, it gives off emissions like carbon dioxide, sulfur dioxide, mercury, ash and particulates, all of which can pollute the environment.

当燃烧煤炭时就产生二氧化碳，二氧化硫、汞、灰尘和微粒，所有这些都污染环境。

That acid rain was coming from the sulfur dioxide pollution spewed by coal-fired power plants upwind in states like Ohio.

这些酸雨来自燃煤发电厂排除二氧化硫，而发电厂们位于俄亥俄州等州逆风处。

Other dangerous pollutants include gases like nitrogen dioxide or sulfur dioxide, which are also produced from burning fuels.

其他危险污染物包括二氧化氮或二氧化硫等体，这些是燃烧燃料产生。

But the Tonga eruption released only a small amount of sulfur dioxide, which scientists have linked to cooling.

但汤加火山喷发只释放了少量二氧化硫，科学家们认为这与降温有关。

That last one being most important.

最后那个二氧化硫是最重要。
