TOXICITY OF 2,4,5-TRICHLOROPHENOL TO THE ANNELID LUMBRICULUS VARIEGATUS AT THREE VALUES OF pH
(1993-06-14)Acute 96-h flow-through toxicity tests with the compound 2,4,5- trichlorophenol (TCP) were conducted using the annelid Lumbriculus variegatus as the test organism. Toxicity tests were conducted at three nominal pH ... -
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 ... -
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 ... -
Toxicity of Mexel 432 to Three Species of Freshwater Organisms
(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 ... -
TOXICITY OF PHENANTHRENE TO SEVERAL FRESHWATER SPECIES
(1986-12)Phenanthrene is a by-product of fossil fuel combusion. It is a constituent of coal tars and has been detected in the stack gases of both oil- and coal-fired power and manufacturing plants. The purpose of this study ... -

TOXICITY OF SILVER TO FATHEAD MINNOWS AT THREE LEVELS OF ORGANIC CARBON
(1992-05-02)Simultaneous renewal 96-h acute toxicity tests were conducted exposing fathead minnows (Pimephales promelas) to silver at three organic carbon levels. The purpose of the tests was to determine £he relationship between the ... -
Toxicity of Silver to Fathead Minnows at Three Values of pH
(1922-04-27)Simultaneous renewal acute toxicity tests were conducted exposing fathead minnows (Pimephales promelas) to silver at three pH levels. The purpose of the tests was to determine if pH of the water affected the toxicity of ... -
Toxicity of Silver to the Fathead Minnow and an Invertebrate in Aged Toxicant Solutions with Laboratory Water and St. Louis River Water
(1993-10-10)Acute toxicity tests with silver nitrate (AgN0₃) were conducted with two species of test organisms. The fathead minnow, Pimephales promelas Rafinesque, and a cladoceran, Daphnia magna, were used to determine the effects ... -
