EC number: 248-440-4 | CAS number: 27394-99-6
Biodegradation in water: screening tests
Administrative data
- Endpoint:
- biodegradation in water: inherent biodegradability
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- other: Study well documented, meets generally accepted scientific principles. Acceptable for assessment; however, use of industrial activated sludge limits reliabilty.
