Toxicity Evaluation of Sediments from Chequamegon Bay, Lake Superior, at Ashland, Wisconsin

Abstract

The Lake Superior Research Institute (LSRI) contracted with SEH to evaluate the toxicity of sediments collected from several near-shore sites in Chequamegon Bay, Lake Superior, at Ashland, Wisconsin. The study area had been sampled previously for chemical analysis of the sediments, and sampling sites had been identified by SEH that would serve either as reference or contaminated sites. LSRI was contracted to perform toxicity tests with three benthic species using solid-phase sediment samples and two planktonic/pelagic species using sediment elutriate samples.
