Short-term toxicity to fish
Administrative data
- Endpoint:
- short-term toxicity to fish
- Type of information:
- read-across from supporting substance (structural analogue or surrogate)
- Adequacy of study:
- supporting study
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- other: A review of existing data. The investigations were performed with potassium bromate. A read across to sodium bromate is justified as both substances dissociated in water and Na+ and K+ ions are naturally occurring species.

- Remarks on result:
- other: Data for juvenile spot.
- Details on results:
- Newly hatched striped bass prolarvae were most sensitive to bromate and had a 96-h LC50 of 30.8 mg/l (as BrO3-). Four-day-old striped bass larvae were less sensitive, with 2- to 10-d LC50s ranging from 605.0 to 92.6 mg/l BrO3-, respectively.
Juvenile spot, which is the age most comparable to standard acute ecotoxicity tests, were least sensitive, with 1- to 10-d LC50s ranging from 698.0 to 278.6 mg/l BrO3-, respectively.
Applicant's summary and conclusion
- Conclusions:
- Juvenile spot showed 1- to 10-d LC50s ranging from 698.0 to 278.6 mg/l BrO3-, respectively.

Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation).
