5.1 Protection of a species requires prevention of unacceptable effects on the number, weight, health, and uses of the individuals of that species. Toxicity tests can be used provide information about the toxicity of a test material to a specific life stage of a particular species of mussel. The primary adverse effects studied are reduced survival or growth.

5.2 Results of toxicity tests might be used to predict effects likely to occur on mussels in field situations as a result of an exposure under comparable conditions.

5.3 Results of toxicity tests might be used to compare the sensitivities of different mussel species and the toxicity of different test materials, and to study the effects of various environmental factors on results of such tests.

5.4 Results of toxicity tests conducted with mussels might be an important consideration when assessing the risks of test materials to aquatic organisms or when deriving USEPA Water Quality Criteria for aquatic organisms (Guide E1241).

5.5 Results of acute toxicity tests (for example, 24- to 96-h tests) might be useful for predicting the results of chronic tests on the same test material with the same species in another water or with another species in the same or a different water. Most predictions take into account the results of acute toxicity tests, and so the usefulness of the results of a chronic toxicity test is greatly increased by reporting also the results of an acute toxicity test conducted with a similar life stage of the same species under the same conditions (Guide E729).

5.6 Results of toxicity tests might be useful for studying the biological availability of, and structure-activity relationships between, test materials.

5.7 Results of toxicity tests will depend on temperature, composition of the dilution water, condition of the test organisms, and other factors.

5.8 Interferences—A number of factors can impede or prevent selection and use of freshwater mussels for toxicity testing (Guide E1850). The following should be considered when selecting a test species and measuring the sensitivity of the test species during toxicity tests.

5.8.1 Handling of field-collected adult mussels resulting from collection or transport to the laboratory might cause excessive mortality or sublethal effects.

5.8.2 The age, health, and physical condition of adult mussels (for example, the presence of parasites, bacteria, and disease) collected from a resident population might not be adequately known.

5.8.3 The physical characteristics of the testing environment (such as water quality, temperature, water flow, light) and food requirements might affect the ability of the test organisms to acclimate, recover from handling, or adapt to the laboratory environ......
