Description of key information
Acutely toxic to aquatic algae.
Key value for chemical safety assessment
- EC50 for freshwater algae:
- 5 mg/L
- EC10 or NOEC for freshwater algae:
- 1.55 mg/L
Additional information
The key study (GLP-guideline study according to OECD 201; BASF SE, 2013) determined a 72 -h ErC50 of 5.00 mg/L and a 72 -h ErC10 of 1.55 mg/L. The nominal concentrations were analytically verified and all validity criteria were met in the test. Based on this data, the substance is acutely toxic to freshwater algae.
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.
