Biodegradation in water: screening tests
Administrative data
Link to relevant study record(s)
- Endpoint:
- biodegradation in water: ready biodegradability
- Type of information:
- experimental study

- weight of evidence
- Reliability:
- 1 (reliable without restriction)
- Justification for type of information:

Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
