An August 31, 1992 National Review piece by Peter Samuel was reprinted by http://nationalreview.com on June 10, 2004 and contains the following ACSH reference:
Dioxin has never been known to do more than cause skin rash even when people have been soaked in high concentrations of the chemical, as in industrial accidents. But the anti-war crowd had successfully anathematized dioxin because of its presence in Agent Orange, used in Vietnam. Agent Orange air crews who mixed and loaded the chemical and spent hours daily in its spray mist showed no higher incidence of disease than their colleagues who had nothing to do with the chemical. Similarly, despite the hullabaloo about Times Beach's road spraying, there was no evidence of higher disease rates in the little town. No special health problems, and no public health justification for doing anything at all -- except perhaps to send in some non-ideological scientists from the American Council on Science and Health to tell residents the facts about dioxin.
