Description of key information
The 72 h EC 50 (yield and growth) for Desmodesmus subspicatus to Ammonium perrhenate was 103.77 and 139.57 mg/L respectively. LOEC and NOEC for both yield and growth were 100 and 50 mg/L respectively.
Key value for chemical safety assessment
Additional information
Evonik Stockhausen (2010) is a GLP compliant, guideline study considered suitable for use as the key study for this endpoint. The study was conducted as a 72 -hour static test. Five test concentrations were used in the study, 6.25, 12.5, 25, 50, 100 mg/L. Recovery rates were between 100% and 104% of nominal concentrations. Test results are therefore based on nominal concentrations.
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.
