Description of key information
In the absence of ecotoxicity data for this substance data have been read across from a soluble rhenium compound, as is standard practice for the hazard and risk assessment of metals. The EC50 value, expressed as potassium perrhenate, is >105.89 mg/L.
Key value for chemical safety assessment
Additional information
Data have been read across from sodium rhenate. 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 limit test at a single test concentration of 100 mg/L. Recovery rates in ICP-OES analysis were 100% of nominal concentrations. Test results are therefore expressed as nominal
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).
