Additional information
The study by Thiebaud (1996) is a static, 48 hour, GLP compliant study, which follows OECD guideline 203. It can be considered reliable and suitable for use as the key study for this endpoint. The results indicate that tetrahydrothiophene is not expected to be toxic to aquatic invertebrates.
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.
