Administrative data
Link to relevant study record(s)
- Endpoint:
- short-term toxicity to aquatic invertebrates
- 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
- Remarks:
- The study has been presented to ECHA in the framework of a notification. The document is now public because presented more than 12 yesrs ago. The summary we received is lacking of many information and we have no indication of the composition of the substance. Justification for Read Across is detailed in the section 13.
- Qualifier:
- according to guideline

- GLP compliance:
- yes
- Details on test solutions:
- Identity and concentration of auxillary solvent for dispersal: dissolution directe dans l'eau de dilution reconstituée
- Test organisms (species):
- Daphnia magna
- Hardness:
- 223 mg CaCO3/l
