Additional information
Evonik Stockhausen (2010) is a GLP complaint, guideline study and is considered suitable for use as the key study for this endpoint. Five test concentrations were used: 6.25, 12.5, 25, 50 and 100 mg/l. Recovery rates in analytical determinations were between 100% and 104% of nominal. Test results were therefore expressed as 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.
