Biodegradation in water: screening tests
Administrative data
Link to relevant study record(s)
- Endpoint:
- biodegradation in water: ready biodegradability
- Type of information:
- read-across from supporting substance (structural analogue or surrogate)
- Adequacy of study:
- weight of evidence
- Justification for type of information:
- See the read-across justification document attached in section 13.
- Reason / purpose for cross-reference:
- read-across source
- Reason / purpose for cross-reference:
- read-across source
- Specific details on test material used for the study:
- Only ammonium dihydrogen citrate is considered in the target as the second constituent is water.
- Key result
- Parameter:
- % degradation (O2 consumption)
- Value:
- 90 - 97
- Sampling time:
- 28 d
- Remarks on result:
- other: based on RA to two sources
- Validity criteria fulfilled:
- not applicable
- Interpretation of results:
- readily biodegradable
- Conclusions:
- Based on read-across to the OECD 306 test with Ammonnium citrate dibasic and the Sturm test (1973) and Closed Bottle test (1974) with citric acid, the pure target substance can be considered as readily biodegradable.

Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
