soot and black carbon

基本解释

And some of the gunk, notably soot or "black carbon", can warm the planet, too.
在颗粒废物中的煤灰或“炭黑”，还会引起全球变暖。
The rest comes from a variety of sources, including hydrofluorocarbons (HFCs), black carbon (soot), methane and nitrogen compounds.
余下来源各异，包括氢氟碳化合物（HFCs），黑碳（煤灰），甲烷与含氮化合物。
It is not possible to tell from this view exactly what pollutants made up the haze on February 20, but it probably contains mostly soot or black carbon and possibly some ground-level ozone.
从照片上我们不能得知污染物是如何造成2月20日的烟雾污染的，但是烟雾中很可能含有大量的煤灰或者炭黑也许还有地面臭氧。
