Biodegradation in water: screening tests
Administrative data
- Endpoint:
- biodegradation in water: ready biodegradability
- Type of information:
- migrated information: read-across from supporting substance (structural analogue or surrogate)
- Adequacy of study:
- key study
- Study period:
- 02.1993-03.1993
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- other: Study was performed according to test guideline and in compliant with GLP for Pigment Blue 56, which is structurally similar to Pigment Blue 61. Thus the study is used for read-across to avoid duplicate tests.
