Description of key information
Arabinofuranosidase was tested for aquatic toxicity in the algal growth inhibition assay and the daphnia immobilisation assay. No fish test was performed, but read-across to alpha-amylase an enzyme belonging to the same sub-subclass was applied for this end point.
For fish: Alpha-amylase was not toxic at the tested concentration of 100 mg/L (58.3 mg aep/L) and thus the NOEC was determined to be 100 mg/L (58.3 mg aep/L). The LC50 value could not be determnined due to the absence of toxicity of the test compound at the tested concentration. Since the two enzymes belong to the same enzyme subsubclass, similar results can be expected for the arabinofuranosidase.
For crustacean Daphnia magna: Under the conditions of the test, arabinofuranosidase, batch PPH40331 was found not to be toxic to Daphnia magna at a nominal concentration up to 100 mg TOS/L (27.2 mg aep/L) after 48h exposure. Thus, no 48h EC50 could be calculated and must be > 100 mg TOS/L (> 27.2 mg aep/L). NOEC is 27.2 mg aep/L.
For algae: Arabinofuranosidase, batch PPH40331 up to a concentration of 100 mg/L (27.2 mg aep/L) was not toxic to Pseudokirchneriella subcapitata as no significant growth inhibition was observed in the present test system. Thus no 72h ErC50 could be calculated and must be > 100 mg TOS/L (> 27.2 mg aep/L). NOEC is 27.2 mg aep/L.
Additional information
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.
