Standard Guide for Conducting Acute Toxicity Tests on Aqueous Ambient Samples and Effluents with Fishes, Macroinvertebrates, and Amphibians
STANDARD published on 1.1.2023
Why Redline?
A PDF redline is a quick and easy way to compare all of the changes between the current, active standard and the previous version.
With a redline you'll immediately see:
Save Time and Trouble!
With a Redline you no longer have to spend time trying to determine what has changed in the new standard! Redlines save you time and ensure you see what the changes are to the standard.
Price
When you select the "Active + Redline" option you get both documents! Best of all, the cost of an Active + Redline is only slightly more than buying the Active Standard by itself.

This guide covers procedures for obtaining laboratory data concerning the adverse effects of aqueous ambient samples and effluents on certain species of freshwater and saltwater fishes, macroinvertebrates, and amphibians, during a short-term exposure, depending on the species, using the static, renewal, and flow-through techniques. These procedures will probably be useful for conducting acute toxicity tests on aqueous effluents with many other aquatic species, although modifications might be necessary. Static tests might not be applicable to effluents that have a high oxygen demand, or contain materials that (1) are highly volatile, (2) are rapidly biologically or chemically transformed in aqueous solutions, or (3) are removed from test solutions in substantial quantities by the test chambers or organisms during the test. Results of acute toxicity tests should usually be reported in terms of a median lethal concentration (LC50) or median effective concentration (EC50). An acute toxicity test does not provide information about whether delayed effects will occur. Specified requirements involving the following are detailed: (1) hazards; (2) apparatus: facilities, special requirements, construction materials, metering system, test chambers, cleaning, and acceptability; (3) dilution water requirements, source, treatment, and characterization; (4) effluent sampling point, collection, preservation, treatment, and test concentrations; (5) test organism species, age, source, care and handling, feeding, disease treatment, holding, acclimation, and quality; (6) procedure: experimental design, dissolved oxygen, temperature, loading, beginning the test, feeding, duration of test, biological data, and other measurements; (7) analytical methodology; (8) acceptability of test; (9) calculation of results; and (1) report of results.
