Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Biodegradation in water: screening tests
Administrative data
Link to relevant study record(s)
Description of key information
The results of the study indicate that less than 10% of tetrahydrothiophene was biodegraded in 28 days. The toxicity control showed that tetrahydrothiophene is not inhibitory to micro-organisms. The sterile control showed that tetrahydrothiophene is not degraded abiotically.
Key value for chemical safety assessment
- Biodegradation in water:
- under test conditions no biodegradation observed
Additional information
Thiebaud (1998) is a GLP compliant, 28-day, aerobic test on secondary effluent, following OECD guideline 301F. The study can be considered reliable and suitable for use as the key study for this endpoint. The results indicate that tetrahydrothiophene is not readily biodegradable and may therefore be persistent in the environment. This is supported by a QSAR calculation, which predicts that tetrahydrothiophene is not expected to biodegrade.
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.
