Acute flow-through toxicity tests were conducted with 1 nin e chlorinated organic compounds and four species of freshwater organisms. Eight compounds (1 ,2-dichlorobenzene, 1 ,4-dichlorobenzene, 1,2,4-tirchlorobenzene,hexa­ ...

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 ...

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 shown ...

The completion of this fifth volume of Acute Toxicities of Organic Chemicals to Fathead Minnows (Pimephales promelas) marks a milestone for our QSAR research program. The five volumes contain original data from 777 ...

Over 60,000 chemicals exist in United States commerce (U.S. EPA, 1982). This inventory expands each year as 200 to l,000 new chemicals are advanced into commercial production (Muir, 1980). ...

Acute toxicity values for aquatic life continue to be useful for pre­liminary assessment of the potential for harm in the environment by chemicals. The end-point for an Lc50 (concentration of chemical necessary to kill ...

In this, the fourth volume of acute toxicity data on organic chemi­cals, we pay tribute to the species which has made this possible. The fathead minnow (Pimephales promelas) is well suited to laboratory studies and was ...

The contents of the second volume of Acute Toxicities of Organic Chemicals to Fathead Minnows (Pimephales promelas} provide additional infor­mation for the ongoing development of an aquatic toxicology data ...

The utility of chemical toxicity testing as an environmental protection strategy has been an accepted practice since the mid 1900s. Extensive aquatic toxicity testing began in the 1960s and tests were categorized into ...
