Short-term toxicity to fish
Administrative data
- Endpoint:
- short-term toxicity to fish
- Type of information:
- experimental study
- Adequacy of study:
- supporting study
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- other: Although the study has been conducted with triiron tetraoxide at a test concentration well exceeding the solubility the test is deemed appropriate as supporting evidence for the non-classification of triiron tetraoxide products
