Biodegradation in water: screening tests

Currently viewing:

Administrative data

Endpoint:
biodegradation in water: ready biodegradability
Type of information:
experimental study
Adequacy of study:
weight of evidence
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
guideline study
Justification for type of information:
The substance in this registration is chemically similar and has the same relevant functional groups as the test substance. Therefore, with high probability, it can be assumed, that the biodegradation rate is comparable.
