EC number: 483-990-0 | CAS number: -
Biodegradation in water: screening tests
Administrative data
- Endpoint:
- biodegradation in water: ready biodegradability
- Type of information:
- read-across based on grouping of substances (category approach)
- Remarks:
- APP category
- Adequacy of study:
- key study
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- other: Category is coherent for more than 10 endpoints. All members are ready biodegradable and even for some of them anaerobic studies are available and show also ready biodegradability under these conditions.
- Justification for type of information:
- Discussed in the document attached
