Short-term toxicity to fish
Administrative data
Link to relevant study record(s)
- Endpoint:
- short-term toxicity to fish
- Type of information:
- other: read-across from supporting substance (structural analogue or surrogate)
- Adequacy of study:
- key study
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- guideline study with acceptable restrictions
- Remarks:
- The complete read across justification is detailed in section 13. Test substance is an isomer of the substance under registration; structural difference is not expected to significantly impact the toxicity to fish. Source study has reliability 2: only limited information available from a migrated NONS file, as per Article 25(3) request.
- Qualifier:
- according to guideline
- Guideline:
- EU Method C.1 (Acute Toxicity for Fish)
- Principles of method if other than guideline:
- No information on the method is available.
- GLP compliance:
- yes
- Test organisms (species):
- Cyprinus carpio
- Test type:
- not specified
- Water media type:
- freshwater
- Total exposure duration:
- 96 h
- Duration:
- 96 h
- Dose descriptor:
- LC50
- Effect conc.:
- ca. 46 mg/L
- Nominal / measured:
- nominal
- Conc. based on:
- not specified
- Basis for effect:
- mortality (fish)
- Conclusions:
- LC50(96h) = 46 mg/l (nominal)
- Executive summary:
Method
Test conducted according to EU method C.1. No information on method is available. Available data derived from migrated NONS file, as per Article 25(3) request, with permission to refer granted by ECHA.
Results
LC50(96h) = 46 mg/l (nominal)
Reference
Description of key information
LC50 (96h) = 46 mg/l.
Key value for chemical safety assessment
Fresh water fish
Fresh water fish
- Effect concentration:
- 46 mg/L
Additional information
Due to the lack of data on Direct Blue 273, a read across approach was followed.
In a 96 -hour study on toxicity to fish according to EU method C.1 using Similar Substance 01, i.e. an isomer of Direct Blue 273 differing only for the position of a functional group on an aromatic ring, a LC50 of 46 mg/l was found. Based on the structural similarity, such value was considered as representative also for Direct Blue 273.
Further details on the read across approach are included in section 13.
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).
