Description of key information

The toxic effect of the test item L-alanine to Daphnia magna was assessed in a static limit-test. The 48-hour NOEC was determined to be 100 mg test item/L. The 48-hour LOEC was determined to be > 100 mg test item/L and the 48-hour EC50 value was determined to be > 100 mg test item/L. 

Key value for chemical safety assessment

Additional information

L-Alanine did not show short-term toxicity to Daphnia magna. It can be concluded that L-alanine does not exhibit short-term toxicity to aquatic invertebrates.
