Description of key information
EC50 > 100 mg/L, NOEC = 10 mg/L (OECD 201, Scenedesmus subspicatus)
Key value for chemical safety assessment
- EC50 for freshwater algae:
- 100 mg/L
- EC10 or NOEC for freshwater algae:
- 10 mg/L
Additional information
Sodium triacetoxyborohydride was tested in a GLP study performed according to OECD 201. Alga Scenedesmus subspicatus was exposed to concentrations of 10, 22, 46 and 100 mg/L for 72 h under static conditions. The determined EC50 after 72 -h was > 100mg/L, the NOEC was 10 mg/L and the LOEC was 22 mg/L, while the EC10 was determined to be 16 mg/L based on biomass and 82 mg/L based on growth rate, respectively.
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.
