Description of key information
Acutely harmful for aquatic algae and cyanobacteria.
Key value for chemical safety assessment
Additional information
The toxicity to aquatic algae and cyanobacteria was assessed in a study according to OECD guideline 201 under consideration of GLP. The test substance is a sparingly soluble UVCB. Therefore the test substance concentrations were prepared under general guidance of OECD 23. The algae (Pseudokirchneriella subcapitata) were exposed to 0 (control), 4.6, 10, 22, and 100 mg/L test substance as nominal concentrations (loading rates). After an exposure duration of 72h the EC50 (growth rate) was determined to be 34 mg/L (nominal) and the EC10 25.4 mg/L.
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.
