Polychlorinated Dibenzo- <i>p</i> -dioxins and Dibenzofurans in Sediments from Siskiwit Lake, Isle Royale

Abstract

Polychlorinated dibenzo-p-dioxins and dibenzofurans were found in sediment from Siskiwit Lake on Isle Royale, Lake Superior, a location which can receive only atmospheric inputs. The source of these compounds is the atmospheric transport of dioxins and furans formed by combustion of domestic and chemical waste.
