Abstract |
In October of 1948, Donora, Pennsylvania was subjected to an acute smog episode. From November 1948 through March 1949 the United States Public Health Service conducted a community survey of the Donora area in order to determine who had been affected by this episode. The principle objective of the investigation, begun in the Fall of 1956, eight years after the smog episode, was to contrast the subsequent health histories of those persons included in the 1948 community survey who were reported to be affected with those who were reported not to be affected. |
