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 ... -
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 ... -
The Effects of Food and Test Solution Age on the Toxicity of Silver to Three Freshwater Organisms
(1993-09)Acute toxicity tests were conducted to determine the effects on the toxicity of silver of having food present in test chambers and the effect of having silver solutions of different ages. Tests were conducted in two ... -
