|Significance and Use|
5.1ï¿½Protection of an aquatic species requires prevention of unacceptable effects on populations in natural habitats. Toxicity tests are conducted to provide data that may be used to predict what changes in numbers and weights of individuals might result from similar exposure to the test material in the natural aquatic environment. Information might also be obtained on the effects of the material on the health of the species.
5.2ï¿½Results of life-cycle tests with 5.2.1ï¿½Life-cycle tests with 5.2.2ï¿½Life-cycle tests with 5.2.3ï¿½Life-cycle tests with 5.2.4ï¿½Life-cycle tests are used to evaluate the biological availability of, and structure-activity relationships between, test materials and test organisms.
5.3ï¿½Results of life-cycle tests with 1.1ï¿½This guide covers procedures for obtaining laboratory data concerning the adverse effects of a test material (added to dilution water, but not to food) on 1.2ï¿½These procedures are applicable to most chemicals, either individually or in formulations, commercial products, or known mixtures. With appropriate modifications, these procedures can be used to conduct tests on temperature, dissolved oxygen, pH, and on such materials as aqueous effluents (also see Guide ), leachates, oils, particulate matter, sediments, and surface waters. The technique, (renewal or flow-through), will be selected based on the chemical characteristics of the test material such as high oxygen demand, volatility, susceptibility to transformation (biologically or chemically), or sorption to glass.
1.3ï¿½Modification of these procedures might be justified by special needs or circumstances. Although using appropriate procedures is more important than following prescribed procedures, results of tests conducted using unusual procedures are not likely to be comparable to results of standard test procedures. Comparison of results obtained using modified and unmodified versions of these procedures might provide useful information on new concepts and procedures for conducting life-cycle toxicity tests with D. magna. provides modifications for conducting the chronic toxicity test method with 1.4ï¿½This guide is arranged as follows:
1.5ï¿½The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.6ï¿½This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. Specific hazard statements are given in Section .
1.7ï¿½This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
