Biodegradation in water: screening tests
Administrative data
Link to relevant study record(s)
- Endpoint:
- biodegradation in water: ready biodegradability
- Type of information:
- other: experimental study on hydrolysis product n-Butanol
- Adequacy of study:
- key study
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- study well documented, meets generally accepted scientific principles, acceptable for assessment
- Principles of method if other than guideline:
- BOD (Standard Methods for the Examination of Water and Wastewater. 1971. 13th Ed. American Public Health Association, New York, NY)
- GLP compliance:
- no
- Oxygen conditions:
- aerobic
- Inoculum or test system:
- sewage, domestic, non-adapted
- Duration of test (contact time):
- 20 d
- Initial conc.:
- 3 mg/L
- Based on:
- test mat.
- Details on study design:
- Settled domestic wastewater was filtered through glass wool and added (3 mL/bottle) to clean 300 mL BOD bottles. Aerated dilution water containing minerals specified in the method were added to the bottles along with buffer. Test chemical was added to the bottles. Potential oxygen demand was 3 to 30 mg/L over 20 days. Dissolved oxygen was measured on days 0, 5, 10, 20 using a dissolved O2 meter. When oxygen decreased to <4 mg/L in any bottle, it was reaerated. Concentration: 3, 7 and 10 mg/L (at least two are represented)

Reference
Description of key information
Tributyl borate is rapidly hydrolyzed to Boric acid and n-Butanol in the presence of water (18.3 sec at 21°C).
Boric acid is an inorganic compound and not degradable and thus, not subject to biodegradation.
Reliable data of the hydrolysis product n-Butanol are used to address the endpoint, which is entirely appropriate to draw conclusions on the biodegradation of Tributyl borate: n-Butanol is readily biodegradable (according to OECD criteria).
Key value for chemical safety assessment
- Biodegradation in water:
- readily biodegradable
