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.
