Biodegradation in water: screening tests
Administrative data
Link to relevant study record(s)
- Endpoint:
- biodegradation in water: ready biodegradability
- Type of information:
- read-across based on grouping of substances (category approach)
- Adequacy of study:
- weight of evidence
- Justification for type of information:
- Please refer to the category justification documentation provided in the category object.
- Parameter:
- other: % degradation
- Value:
- > 60 - <= 100
- Sampling time:
- 28 d
- Conclusions:
- The ready biodegradability of the target substance was assessed in a weight of evidence approach based on the grouping of substances (category approach). The substances of the Alcohol Ethoxylates (AE) category are readily biodegradable according to OECD criteria.
- Executive summary:
The ready biodegradability of the target substance was assessed in a weight of evidence approach based on the grouping of substances (category approach). The available experimental data on the substances of the Alcohol Ethoxylates (AE) category indicates a rapid degradation of the substances under aerobic conditions. All test substances reached degradation rates > 60% and thus are regarded as readily biodegradable according to OECD criteria.
