smog (n.)

1905年，由 smoke（名词）和 fog（名词）混合而成，"仿效刘易斯·卡罗尔的例子" [克莱因； 见 portmanteau ]。据说是在伦敦的一篇由煤烟减少协会财务主管 H.A.德沃先生所读的论文中首次出现，尽管他似乎没有声称自己创造了这个词。

At a recent health congress in London, a member used a new term to indicate a frequent London condition, the black fog, which is not unknown in other large cities and which has been the cause of a great deal of bad language in the past. The word thus coined is a contraction of smoke fog "smog" — and its introduction was received with applause as being eminently expressive and appropriate. It is not exactly a pretty word, but it fits very well the thing it represents, and it has only to become known to be popular. [Journal of the American Medical Association, Aug. 26, 1905]

在伦敦最近的一次健康大会上，一位成员使用了一个新术语来表示伦敦经常出现的黑雾，这在其他大城市也不罕见，过去曾引起了很多不良言论。这个新创造的词是 smog，是 smoke fog 的缩写，它的引入得到了掌声，因为它非常生动形象。它不是一个很漂亮的词，但它非常贴切地描述了它所代表的事物，只要它被广泛认识，它就会变得流行。[美国医学协会杂志，1905年8月26日]

Smaze   （与 haze（名词）一起）是从1953年开始使用的。
