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:
- key study
- Justification for type of information:
- REPORTING FORMAT FOR THE CATEGORY APPROACH
This read-across hypothesis is based on a category approach. Within this approach, it is assumed that, based on structural similarity, the source and target substances will display similar toxicological properties. Of the category approaches detailed in the RAAF guidance document, Scenario 6 “Difference compounds have the same type of effect(s)” is considered the most appropriate hypothesis for this read-across. This read-across is detailed in the read-across justification document provided under 'Assessment Report'.
