Dioxin in Sediments: Application of Toxic Equivalents Based on International Toxicity Equivalency Factors to Regulation of Dredged Material

Abstract

This technical note explains the origin and meaning of the dioxin toxic equivalent (TEQ) concept, reviews the application of TEQs to dredged sediment evaluations, examines the underlying assumptions of the application, considers appropriate and inappropriate usage, and discusses a possible alternative to the analytical chemistry-based calculation of TEQs.
