Biodegradation in water: screening tests
Administrative data

Description of key information
The biodegradability of octane-1-thiol has been read across from tert-dodecanethiol. The results of the biodegradation test for tert-dodecanethiol indicate that the substance is not readily biodegradable. Oxygen consumption in vessels containing tert-dodecanethiol was negligible, indicating that it was not readily degradable under the conditions of the test.
Key value for chemical safety assessment
- Biodegradation in water:
- under test conditions no biodegradation observed
Additional information
The biodegradability of octane-1-thiol has been read across from tert-dodecanethiol. Jenkins (1990) is a GLP-compliant, closed bottle ready biodegradability study, with reference compounds, testing oxygen consumption, which follows OECD guideline 301D. Oxygen consumption in vessels containing tert-dodecanethiol was negligible, indicating that it was not readily degradable under the conditions of the test.
Data are also available for octane-1 –thiol from Thiebaud (1994), who carried out a closed bottle biodegradability test following OECD guideline 301D. However, only a summary of the study is available, and therefore the study cannot be fully evaluated. Although the conclusion states that octane-1 -thiol is not readily biodegradable, there is no data provided for octane-1 -thiol in the summary.
