Smog

According to the Oxford English Dictionary, smog, a thoroughly unpleasant word used to describe air pollution, was first referenced in July of 1905 in the Daily Graphic. One Dr. des Voeux, treasurer of the Coal Smoke Abatement Society, is said to have used the term in a paper delivered to Congress. Suitably enough, smog, is a conflation of "smoke" and "fog." Euphemisms abound for smog in smog-bound cities. Haze is a particularly troubling one.
