Acute and early life stage_ (ELS) toxicity tests were conducted with fathead minnows (Pimephales promela$) and seven chemicals: 2,4-dinitrophenol (2,4-DNP), 4,6-dinitro-o- cresol (DNOC), 2-sec -butyl--4,6-dinitrophenol ...

Physical and chemical characteristics of water may affect the biological avail ability and toxicity of chemicals in aquatic environments. Hardness, alkalinity, pH, dissolved organic matter, and suspended materials ...

The test substance trifluralin, a,a,a-trifluro-2,6-dinitro-N,N-dipropyl-p­-toluidine is a yellow-orange crystal that is used commercially as an herbicide. It is used as a selective preemergence herbicide. Its solubility ...

The test substance trifluralin, a,a,a-trifluro-2,6-dinitro-N,N-dipropyl-p­ toluidine, is a yellow-orange crystal that is used commercially as a herbicide. Its solubility in water is less than 1 mg/L (Farm Chemicals ...

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 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 ...
