Short-term toxicity to fish
Administrative data
- Endpoint:
- short-term toxicity to fish
- Type of information:
- migrated information: read-across from supporting substance (structural analogue or surrogate)
- Adequacy of study:
- key study
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- other: see 'Remark'
- Remarks:
- Guideline study with acceptable restrictions. Iron(II)Oxide belongs to the iron oxides family and presents comparable physico chemical properties, leading to similar behaviour for the all members of the iron oxide substances. In particular, based on affinity of the chemical structure, Iron Oxide (Fe3O4) and Iron(III)Oxide (Fe2O3) are selected to support read across for the Iron(II)Oxide dossier. Full justification paper is provided in the current Summary Section.

Applicant's summary and conclusion
- Validity criteria fulfilled:
- yes
- Executive summary:
Within 96 hours no effect (LC0) on Brachydanio rerio was observed up to a concentration of >= 50000 mg/l, and a 96-hour LC90 of ca. 100000 mg/l was obtained. The method used was a proposed procedure for lethal effect on Zebrabaerbling. (Federal Environmental Agency Germany May 1984), (Bayer AG 1989).
