Description of key information

Determination of the acute short-term toxicity of m-(2,3 -epoxypropoxy)-N,N-bis(2,3 -epoxypropyl)aniline in Daphnia magna.

Key value for chemical safety assessment

EC50/LC50 for freshwater invertebrates:
18 mg/L

Additional information

In the key study experiment, a 48 -h acute toxicity study, water fleas (Daphnia magna) were exposed to m-(2,3-epoxypropoxy)-N,N-bis(2,3 -epoxypropyl)aniline under static conditions at the following nominal concentrations (final test): (blank-control), 0.10, 0.32, 1.0, 3.2, 10, 32 and 100% of the water soluble fraction prepared at 100 mg/L. The test substance did not induce significant acute immobilisation of Daphnia magna at 10 mg/L after 48 hours of exposure based on analytically confirmed nominal exposure concentrations. The 48h-EC50 was 18 mg/L based on analytically confirmed nimonal exposure concentrations (95% confidence interval between 10 and 32 mg/L) The study is conidered to be reliable without restrictions.
