Biodegradation in water: screening tests

Administrative data

Endpoint:
biodegradation in water: screening tests
Type of information:
migrated information: read-across based on grouping of substances (category approach)
Adequacy of study:
key study
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
other: Category is coherent for more than 10 endpoints. All members are ready biodegradable and even for some of them anaerobic studies are available and show also ready biodegradability under these conditions.

Applicant's summary and conclusion

Validity criteria fulfilled:
yes
Interpretation of results:
readily biodegradable
Conclusions:
APP category approach based on 8 biodegradation studies allows an estimation of APP-6512 (C10-12) 28-day aerobic biodegradability as equal to 83.2±9.3%.
