An Account of Two Decades of Applied Research and Public Education 1969 to 1989
(1989-04-28)
The Center for Lake superior Environmental studies (CLSES) was created in the late 1960's, a period of national environmental concern. The founding scientists, from the departments of biology, chemistry, geology and ...
ACUTE TOXICITY OF SILVER TO SELECTED FRESHEATER INVERTEBRATES
(1986-01)
Silver is used in jewelry, silverware, coins, electroplating, .and photo graphic
processes. It is a waste product in the manufacture of these products and
processes. Also, metal mining ...
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 ...
ACUTE TOXICITY OF ANTIMONY III TO SEVERAL SPECIES OF FRESHWATER ORGANISMS
(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 ...
TOXICITY OF ALUMINUM TO FRESHWATER ORGANISMS IN WATER OF pH 6.5 - 8.5
(1982)
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 ...
ACUTE TOXICITY AND CHRONIC EFFECTS OF BIS (TRI-N-BUTYLTIN) OXIDE TO SEVERAL SPECIES OF FRESHWATER ORGANISMS
(1986-12)
Triorganotin compounds are widely used as industrial biocides, agricultural chemicals, wood
preservatives, and marine antifoulants. Although the in vitro fungicidal biological activity of
the triorganotins was recognized ...

Development of Bioassay Procedures for Defining Pollution of Harbor Sediments - Project Summary
(1980)
This research investigates bioassay methods which may be useful in assessing the degree of
pollution of harbor sediments. Procedures studied include 96 hr toxicity tests employing
Hexagenia limbata, Daphnia magna and ...
