Acknowledgments

The research reported here has depended on many others, though I alone am responsible for the judgments expressed in the current article. My research on toxins and crime was originally funded by the E.P.A. Office of Criminal Enforcement, where Martin Topper was exceptionally helpful. Massachusetts blood lead data were collected under the direction of Dr. James Sargent of the Dartmouth Medical School and Prof. Adrian Bailey, who kindly made them available. Christopher Covel, an outstanding geologist, led me to the deceptively beautiful lands of Lake Chibougamau, Quebec – and in so doing, introduced me (to the limit of available funds) to studying the awesome pollution challenging the extraordinary Oujé-bougoumou Cree and Kanesatake Mohawk. Last but not least, I thank the many Dartmouth students who have assisted in the preparation and preliminary analysis of the data that are described here, and Peter Meiers for bringing German research to the attention of my colleague, Myron Coplan.
