OECD 202 Daphnia Acute Immobilisation Test
The OECD 202 Daphnia Acute Immobilisation Test (AIT) is a standardized method used to assess the acute toxicity of substances towards the aquatic organism Daphnia magna. This test is widely recognized and employed by regulatory bodies globally, including the European Union and United States Environmental Protection Agency. The OECD 202 Daphnia AIT provides a robust framework for evaluating the potential impact of chemicals on freshwater ecosystems.
The test method involves exposing Daphnia magna to test solutions under defined conditions over a 48-hour period. During this time, the number of immobile daphnids is recorded at regular intervals. The primary endpoint of the OECD 202 Daphnia AIT is the determination of the EC50 (median effective concentration), which represents the concentration of the test substance that immobilizes half of the test organisms.
The OECD 202 Daphnia AIT plays a crucial role in environmental risk assessment, particularly for chemicals used in agriculture, manufacturing, and wastewater treatment. The results from this test can inform decision-making processes related to chemical usage, product development, and environmental compliance. This method is also pivotal in the research and development stages of new products where understanding potential impacts on aquatic life is essential.
The OECD 202 Daphnia AIT is designed to be cost-effective and efficient while ensuring high-quality data that can be used for regulatory submissions. The test protocol, as defined by OECD guidelines (OECD Guideline for Testing of Chemicals: 201), provides clear instructions on specimen preparation, exposure conditions, observation times, and endpoints. Compliance with these guidelines ensures consistency across various laboratories, enhancing the reliability of results.
One key advantage of the OECD 202 Daphnia AIT is its ability to provide rapid insights into a chemical's potential environmental impact. This information can be used early in the development process to guide formulation and reformulation efforts, thereby reducing risks associated with product release. Additionally, the test method supports regulatory compliance by providing data that meets international standards such as OECD guidelines.
The OECD 202 Daphnia AIT also offers a means for assessing the environmental fate of chemicals through endpoint modeling. This involves using the EC50 values obtained from the test to predict the likelihood and extent of chemical accumulation in aquatic environments. Such information is invaluable for understanding long-term effects on ecosystems.
The OECD 202 Daphnia AIT's robustness extends beyond immediate toxicity assessment; it can also be used to evaluate the potential for secondary impacts, such as reproductive impairment or growth inhibition. By incorporating these additional endpoints into the testing protocol, laboratories can provide comprehensive data that aids in more holistic risk assessments.
In summary, the OECD 202 Daphnia AIT is a vital tool in environmental toxicology and risk assessment. It offers a standardized approach to evaluating the acute toxicity of chemicals towards aquatic organisms, providing essential information for regulatory compliance and product development. The test's ability to inform early-stage decision-making processes and support long-term environmental stewardship makes it an indispensable component of modern chemical testing.
