TOXICITY AND METABOLISM STUDIES WITH EPA PRIORITY POLLUTANTS AND RELATED CHEMICALS IN FRESHWATER ORGANISMS
(1985)
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 Chironomus tentans Survival and Growth Bioassay: A Study of the Effect of Reduced Larval Growth Upon the Following Generation and an Application of the Bioassay in Evaluating Sediment Quality
(1993-09)
A life-cycle study was conducted with Chironomus tentans to assess the significance
of growth retardation of second to third instar larvae over a 10-d test period on long-term
survival, emergence success, and fecundity. ...
SEDIMENT QUALITY EVALUATION IN THE LOWER FOX RIVER AND SOUTHERN GREEN BAY OF LAKE MICHIGAN
(1991-04)
The quality of sediment from the Lower Fox River between the dam at DePere, Wisconsin, and the
mouth of the river, and from the southern tip of Green Bay, Lake Michigan, was evaluated at 12
sites by a combination of ...
TOXICOLOGICAL STUDIES WITH HERBICIDES, SELECTED EPA PRIORITY POLLUTNATS AND RELATED CHIMCALS IN AQUATIC ORGANISMS
(1982-11)
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 ...
ESTIMATES OF "NO EFFECT" CONCENTRATIONS OF SELECTED PESTICIDES IN FRESHWATER ORGANISMS (YEAR II) 1 April 1979 - 31 March 1980
(1980)
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, ...
ESTIMATES OF "NO EFFECT" CONCENTRATIONS OF SELECTED PESTICIDES IN FRESHWATER ORGANISMS (YEAR III) 1 April 1980 - 23 May 1981
(1981)
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, ...
TOXICITY OF ALUMINUM TO FRESHWATER ORGANISMS IN WATER OF pH 6.5 - 8.5
(1984-11-26)
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 ...
WATER QULITY STUDY ON THE FLAMBEAU RIVER UPSTREAM AND DOWNSTREAM FROM A PROPOSED MINE SITE NEAR LADYSMITH, WICONSIN
(1991-03-19)
The Kennecott Copper Corporation has developed plans for construction of an open pit copper and
gold mine immediately adjacent to the Flambeau River near Ladysmith, Wisconsin. The Great Lakes
Indian Fish and Wildlife ...
ACUTE TOXICITY OF SELENIUM (IV) AND SELENIUM (VI) TO FRESHWATER ORGANISMS
(1985-12)
The primary sources of selenium in the environment are geologic and industrial. Selenium closely
resembles sulfur chemically, and sulfur or sulfide deposits of bismuth, copper, iron, lead,
mercury, silver, and zinc ...
SITE-SPECIFIC ACUTE AND CHROMIC AQUATIC TOXICITY TESTING - WESTERN LAKE SUPERIOR SANITARY DISTRICT TREATMENT PLANT EFFLUENT STUDIES
(1982-11)
A need exists for the characterization of natural waters regarding their capacities for reducing the toxic effects of discharged wastes to aquatic organisms An understanding of effects of naturally occurring ligands in ...
