The Deadly Smog Episode of Donora

 


In October 1948, the industrial town of Donora, situated along the Monongahela River in Southwestern Pennsylvania sustained a five-day temperature inversion. Smoke from the steel and zinc mills could not rise above the hills that surrounded the town. Small and large particles of pollution were inhaled with deadly consequences. By the time winds and rain finally came to wash away the pollution, twenty people had died and 6,000 were ill. The Clean Air Act began because of the Donora Smog.

The deadly smog episode of Donora is the subject of a new exhibit at the Arizona Health Sciences Library at the University of Arizona. The exhibit will open November 1st, 2005 and runs through end of December.

The library is open to the general public from 5:00 am to 10:00 pm.
