Description of key information
Additional information
For the aquatic toxicity of N-Acetyl-DL-tryptophan (CAS 87-32-1) OECD guideline studies performed under GLP standards are available for all trophic levels (fish, aquatic invertebrates and algae), including microorganisms.
The short-term toxicity tests for fish (OECD 203), aquatic invertebrates (OECD 202) and algae (OECD 201) showed no effects up to a nominal concentration of 100 mg/L. Long-term toxicity data are available only for algae with an ErC10 > 100 mg/L. The respiration inhibition study (OECD 209) resulted in an NOEC (3 h) of ≥ 1000 mg/L, indicating that the substance is not toxic to aquatic microorganisms.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
