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 perrhenic acid, is >91.95 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
