Description of key information
NOEC = 100 mg/L for Scenedesmus subspicatus (OECD 201, limit test)
Key value for chemical safety assessment
- EC50 for freshwater algae:
- 100 mg/L
Additional information
One GLP study according to OECD Guideline 201 was performed in order to investigate the toxicity of Y-15099 (CAS 220727-26-4) to aquatic algae (Bätscher, 2001). This study was conducted using the green algae Scenedesmus subspicatus exposed to a filtered test solution of nominal 100 mg/L for 72 h. However, the mean measured concentration in the test vessels was 0.0018 mg/L (below LOQ) which is related to the hydrolytic instability of the test substance. Thus, the hydrolytic degradation products of the test substance were tested as well. No inhibitory effects on algal growth were observed resulting in a NOEC of = 100 mg/L (nominal) and an EC50 of > 100 mg/L (nominal).
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.
