This book has benefited from the suggestions and criticism of many people. It developed from a symposium on the topic that I chaired at the 1994 annual meeting of the American Psychiatric Association, with presentations by Aristide Esser, Aaron Katcher, Robert Lifton, Herbert Needleman, Richard Restak, and Bernard Weiss.
Producing a book turned out to be laborious but highly rewarding; the patience, flexibility, and professionalism of the authors made it an instructive and enjoyable experience. I am particularly grateful for the editorial help and advice of Randall White and the interest and encouragement of Howard Frumkin.
Among others who commented on parts of the manuscript or contributed material, I wish to thank Dan Oren, NIMH; Rosie Sokas, George Washington University; Phyllis Windle, formerly of the congressional Office of Technology Assessment; David Wallinga, NRDC; Pamela Tucker, ATSDR; and Kate Oliver, NIH, who prepared the appendix.
On countless occasions I could rely on the advice of members of my family. My wife read and worked on the manuscript in all its versions; the final result owes much to her skills and experience as a writer and editor. I am deeply grateful for her work, her interest, and her never failing support.
Any remaining editorial shortcomings are my responsibility.
