Short-term toxicity to fish

Currently viewing:

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

Applicant's summary and conclusion

Validity criteria fulfilled:
yes
Conclusions:
LL0 and LC50 > 10000 mg/L
Executive summary:

For triiron tetraoxide a 96-hour LL0 (lethal loading) of >= 10000 mg/l (nominal concentration) was observed on Brachydanio rerio. Directive 92/69/EEC, C.1, equivalent to the OECD 203 was the method used.
