Acute, static exposures with aluminum were completed at the campus of the University of Wisconsin-Superior (UW-S) using two species of freshwater organisms (brown Planaria, Dugesia tigrina; daphnid, Daphnia magna). The ...

Enclosed is the data for ten of the Great Lakes National Program Office fish samples analyzed for biosignificant polychlorinated dibenzo-p-dioxins (PCDDs) and polychlorinated dibenzofurans (PCDFs).

Twenty-two chemicals from the EPA priority pollutant list were studied for their acute and/or chronic toxicity to selected freshwater organisms. These included 1,2-dichloroethane, 1,1,2-trichloroethane, 1,1,2,2-tetra ...

The need for new and improved procedures to determine primary and secondary (ecological) effects of pesticides on the non-target biota in natural aquatic systems necessitated the research effort that has resulted in ...

Toxicological studies were conducted in two areas: (l) the toxicity, bioconcentration potential and metabolism of five herbicides in fish; and (2) the toxicity and/or metabolism of priority pollutants and related chemicals ...

Work began on thirteen assigned chemicals to determine acute and chronic toxicities bioconcentration, and'metabolism in freshwater organisms. The assigned chemicals for testing are as follows: di-2-ethylhexylphthalate, ...

Toxicity tests with 18 chemicals and 3 species of test organisms were completed during the quarter for a total of 19 tests. Seventeen tests were acute exposures and one was an algal assay. Seven tests were with alcohols, ...

The Center for Lake Superior Environmental Studies of the University of Wisconsin-Superior, Superior, Wisconsin 54880 has completed acute toxicity tests with eighteen organic compounds. Fathead minnows, Pimephales ...

Most studies on the toxicity of aluminum (Al) to aquatic life have been conducted in acidic waters, due to concerns centered around surface water acidification. Fewer studies have been conducted in waters of neutral ...

The lands that border thousands of streams in Wisconsin contain unique and valuable qualities. These border lands-called riparian areas -play a critical role in protecting water quality,' soil, fish and wildlife. ...
