Short-term toxicity to aquatic invertebrates

Currently viewing:

Administrative data

Endpoint:
short-term toxicity to aquatic invertebrates
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 iron oxide at a test concentration well exceeding the solubility the test is deemed appropriate as supporting evidence for the non-classification of iron oxide products
