National Technical Reports Library

The National Technical Information Service acquires, indexes, abstracts, and archives the largest collection of U.S. government-sponsored technical reports in existence. The NTRL offers online, free and open access to these authenticated government technical reports. Technical reports and documents in its repository may be available online for free either from the issuing federal agency, the U.S. Government Publishing Office’s Federal Digital System website, or through search engines.

Acute Toxicity of Selected Toxicants to Six Species of Fish.

PB252488

Publication Date	1976
Personal Author	Cardwell, R. D.; Foreman, D. G.; Payne, T. R.; Wilbur, D. J.
Page Count	128
Abstract	The relationship between median lethal concentration and exposure time was determined for five chemicals and up to six species of freshwater fish in a flow-through system. The lowest median lethal concentrations found were 0.114 mg/l for sodium cyanide, 0.118 mg/l for sodium pentachlorophenate, 2.9 mg/l for selenium dioxide, 18.0 mg/l for sodium arsenite, 25.4 mg/l for beryllium sulfate, and greater than 100 mg/l for lead chloride. Toxicity curves relating median lethal concentration to exposure time were of three types. One curve, resembling a rectangular hyperbola, characterized the toxicity of sodium cyanide, while another curve, sigmoid in shape, characterized the toxicity of selenium dioxide. Both types of curves were observed in toxicity tests with sodium pentachlorophenate, sodium arsenite and beryllium sulfate. Linear toxicity curves were recorded for some fish species exposed to selenium dioxide, sodium arsenite and beryllium sulfate, but these were usually encountered when exposure times were less than 96 hr.
