Abstract

Sediments taken from Coeur d'Alene Lake, ID with -0.5 m gravity cores were found to be highly reduced. The trace elements detected in the sediments are predominantly associated with an operationally defined sulfidic phase. Results point to a possibility that trace elements could move into overlying waters due either to lake eutrophication or the development of a seasonally anoxic hypolimnion. Metal sulfide formation and metal binding with organic material appear to control the mobilization of most trace elements.
