Description of key information
With high probability acutely not harmful to algae.
Key value for chemical safety assessment
Additional information
The key study is an OECD 201 growth inhibition test with Desmodesmus subspicatus (BASF SE, 2013; report no. 60E0524/11X355). The results are according to all validity criteria; the test substance concentrations are analytically verified. The 72h ErC10 was determined at 135 mg/L (geometric mean measured concentration), the 72h ErC50 is beyond the highest (measured) concentration of 337 mg/L. Based on this result, the substance is assessed to be likely acutely not harmful to 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.
