OECD 241 Daphnia Magna Reproduction Toxicity Test in Water
The OECD 241 test is a fundamental component of aquatic toxicity testing, specifically designed to assess the potential for reproductive toxicity and developmental effects in freshwater organisms. This test provides valuable information regarding the impact of contaminants on reproduction and survival of Daphnia magna, an important indicator species used in environmental monitoring.
During this test, Daphnia magna is exposed to a water sample or a specific chemical under controlled conditions for a period of 10 days. The primary endpoints measured include the number of live offspring produced by each female and the hatching success rate of eggs over time. This data helps determine if there are adverse effects on reproduction due to contamination.
The OECD 241 test is widely recognized as one of the most relevant tests for assessing reproductive toxicity in aquatic environments, especially when considering compliance with international regulations such as REACH and other national laws regarding chemical safety.
This test is not only crucial for regulatory compliance but also plays a key role in research and development efforts aimed at understanding how contaminants affect ecosystems. By identifying potential risks early on, organizations can take proactive measures to mitigate these impacts and ensure sustainable practices.
It’s worth noting that the OECD 241 test is part of a broader suite of tests used globally to evaluate chemical substances for their environmental impact. The results from this test contribute significantly to informed decision-making processes within industries ranging from pharmaceuticals to manufacturing, ensuring that products meet stringent standards before being released into the environment.
The reproducibility and reliability of the OECD 241 test have been validated through extensive validation studies conducted by various bodies around the world. These efforts ensure consistency across different laboratories, which is essential for accurate interpretation of results.

Applied Standards
The OECD Guideline 241 and ISO 11348-5 provide the framework for conducting the Daphnia magna reproduction toxicity test. These guidelines specify detailed procedures including preparation of the test organisms, handling of water samples, exposure periods, observation intervals, and criteria for determining endpoints such as hatching success rates and number of live offspring produced.
Compliance with these standards ensures that tests conducted are consistent both within individual laboratories and between different facilities. This consistency is critical when comparing data from various studies or when submitting results to regulatory authorities like the European Chemicals Agency (ECHA).
