This standard outlines a procedure for conducting acute toxicity tests using Daphnia magna. Acute toxicity tests are used to determine the short-term harmful effects of substances on aquatic organisms. Test Organism: Daphnia magna Straus, a small freshwater crustacean commonly used in ecotoxicology studies. These organisms are sensitive to environmental changes and are often used as indicators of water quality. Test Procedure: The standard provides detailed instructions on how to prepare and conduct the toxicity test. This typically involves exposing a group of Daphnia magna to various concentrations of a test substance over a specified duration. The endpoints of the test include the immobilization of Daphnia magna and the determination of the concentration at which 50% of the test organisms are immobilized (EC50). Data Analysis: The standard may also provide guidance on how to analyze the test results and calculate the EC50 value, which represents the concentration of the substance that causes a 50% reduction in the mobility of Daphnia magna. Reporting: It may specify the information that should be included in test reports, including details of the test conditions, results, and any relevant observations.
