Fifth Edition. – Washington, Dc: U.S. Environmental Protection Agency, October 2002. – 275 P. This manual describes acute toxicity tests for use in the National Pollutant Discharge Elimination System (NPDES) Permits Program to identify effluents and receiving waters containing toxic materials in acutely toxic concentrations. They are also suitable for determining the toxicity of specific compounds contained in discharges. The tests may be conducted in a central laboratory or on-site, by the regulatory agency or the permittee. The Holmesimysis costataAcute Test is specific to Pacific Coast waters and is not listed at 40 Cfr part 136 for nationwide use. This method has been proposed but not yet approved at 40 Cfr part 136.
These methods are restricted to use by, or under the supervision of, analysts experience in the use or conduct of, and interpretation of data from, aquatic toxicity tests. Each analyst must demonstrate the ability to generate acceptable test results with the methods using the procedures described in this methods manual.
This manual was prepared in the established Emsl-cincinnati format.. CONTENTS.
