1,3-Propanediol, 2,2-bis(hydroxymethyl)-, allyl ether

Biodegradation in water and sediment: simulation tests

Link to relevant study record(s)

Reference

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.
