Determination of Percent Dissolved Metals in Freshwater using Simulation Tests

Brooke, Larry T. (1994-02-28)

The animals used in the copper simulation tests were cultured at the UWS culture facilities. Fathead minnows, (Pimephales promelas) were cultured in dechlorinated water from the City of Superior municipal water supply. ...

CONDUCTING TOXICITY TESTS WITH FRESHWATER ORGANISMS, CONDUCTING LITERATURE SERACHES, REVIEWING DATA AND PREPARING WATER QUALITY CRITERIA DOCUMENTS FOR THE COMPOUNDS FLUORANTHENE AND NONYLPHENOL

Brooke, Larry T. (1993-03-24)

The Environmental Health Laboratory at the University of Wisconsin-Superior (UW-S) conducted tests to complete the data set necessary to derive national water quality criteria for nonylphenol. The tests were the eight ...

ACUTE TOXICITY OF SELENIUM (IV) AND SELENIUM (VI) TO FRESHWATER ORGANISMS

Brooke, Larry T.; Call, Daniel J.; Harting, Sandi L.; Lindberg, Carol A.; Markee, Thomas P.; McCauley, Dennis J.; Poirier, Steven H. (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 ...

ACUTE EXPOSURE OF HEXACHLOROBENZENE TO SELECTED FRESHWATER ORGANISMS

Brooke, Larry T.; Call, Daniel J.; Poirier, Steven H.; Harting, Sandi L.; McCauley, Dennis J. (1986-01)

Hexachlorobenzene is a commercially produced chemical of high annual tonnage production used as a feedstock for many chemical manufacturing processes. It is a chemical listed by the U.S., Environmental Protection Agency ...

ACUTE TOXICITY OF ANTIMONY III TO SEVERAL SPECIES OF FRESHWATER ORGANISMS

Brooke, Larry T.; Call, Daniel J.; Poirier, Steven H.; Lindberg, Carol A.; Markee, Thomas P. (1986-08)

Antimony (III) chloride is very soluble in water. The Merck Index (9th ed.) reports a solubility of 1 g SbC13 per 10.1 mL of water. This solution undergoes gradual hydrolysis to antimony oxychloride (SbOCl), which is ...

ACUTE TOXICITY OF 2,4,5-TRICHLOROPHENOL TO FRESHWATER INVERTEBRATES

Brooke, Larry T.; Call, d; Harting, Sandi L.; Poirier, Steven H.; Lindberg, Carol A.; Markee, Thomas P.; McCauley, Dennis J. (1986-01)

The primary source of 2,4,5-trichlorophenol (2,4,5-TCP) contamination in the environment is industrial effluents. The compound itself is used as a germicide and also as a reagent in the synthesis of certain herbicides, ...

Toxicity of Mexel 432 to Three Species of Freshwater Organisms

Brooke, Larry T. (1996-08-01)

Certain species of life are incompatible with mechanisms associated with industries using natural waters for cooling or manufacturing. Many industries have increasing concerns with the interference of water flows due ...

EFFECT OF TEMPERATURE ON OSMOREGULATION OF FRESHWATER POIKILOTHERMS

Brooke, Larry T. (1969-05-08)

Much work has been done during the past few years showing that as the temperature of an organism changes, either upward or down, ionic equilibrium is disturbed within this organism. The degree of disturbance has been ...

FRESHWATER AQUATIC CRITERIA DEVELOPMENT AND TOXICITY TESTING

Sabourin, Thomas D.; Faulk, Robin T.; Coyle, James J.; Brooke, Larry T.; Call, Daniel J.; Harting, Sandi L.; Larson, Loren; Lindberg, Carol A.; Markee, Thomas T.; McCauley, Daniel J.; Poirier, Steven H. (1986)

Aquatic toxicity testing was completed on a number of compounds/elements to supply the necessary data for preparation of Criteria Documents in 1986. The compounds/elements tested included hexachlorobenzene, selenium IV & ...

BIOAVAILABILITY AND TOXICITY OF SILVER TO BENTHIC ORGANISMS IN FRESHWATER SYSTEMS CONTAINING SEDIMENTS OF DIFFERENT CHARACTERISTICS - PROGRESS REPORT (Quarter III)

Call, Daniel J.; Brooke, Larry T.; Markee, Thomas P. (1997-06-30)

This progress report covers the period of time between April 1, 1997, and June 30, 1997. Our efforts were focused on obtaining a better understanding of (l) the chemical behavior of silver in our specific test water as ...
