Biodegradation in water and sediment: simulation tests
Administrative data
Link to relevant study record(s)
- Endpoint:
- biodegradation in water: simulation testing on ultimate degradation in surface water
- Type of information:
- experimental study planned
- Justification for type of information:
- From the existing information, the substance cannot be regarded as ultimately biodegradable. Further information is needed for the PBT/vPvB assessment. An Aerobic Mineralization in Surface Water- Simulation Biodegradation test (OECD 309) is proposed for the substance, as water compartment is considered the worst case due to it's expected to have the lowest NER.
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 309 (Aerobic Mineralisation in Surface Water - Simulation Biodegradation Test)
- GLP compliance:
- yes (incl. QA statement)

Description of key information
The percentage DOC reduction measured after 28 days (at day 29) in both test mediums TI and TII was 11% after correction for the DOC contribution from the inoculum. 1,3-propanediol, 2,2- bis(hydroxymethyl) -, allyl ether therefore cannot be regarded as ultimately biodegradable. Further information is needed for the PBT/vPvB assessment. An Aerobic Mineralization in Surface Water- Simulation Biodegradation test (OECD 309) is proposed for the substance.
