Short-term toxicity to aquatic invertebrates
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:
- supporting 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
- Guideline:
- EU Method C.2 (Acute Toxicity for Daphnia)
- 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
- Duration:
- 48 h
- Dose descriptor:
- EC50
- Effect conc.:
- > 150 mg/L
- Duration:
- 48 h
- Dose descriptor:
- EC100
- Effect conc.:
- > 150 mg/L
- Duration:
- 48 h
- Dose descriptor:
- NOEC
- Effect conc.:
- >= 180 mg/L
- Details on results:
- % concentration loss over test: 0...
- Conclusions:
- EC50 (48h) = 150.0 mg/l
- Executive summary:
The test was conducted according to EU method C.2, and the substance results to have an EC50 (48h) = 150.0 mg/l.

Additional information
No tests are available on Acid Black 001, nevertheless, in order to complete the assessment on aquatic toxicity, tests conduced on a very similar substance were considered. The complete justification for the read across approach is attached at section 13.
A limit test on Daphnia Magna (Stahl) has been performed on Similar Substance 1, showing no mortality at the tested concentration of 180 mg/L. Since the sample concentration is 83% of the nominal concentration, the EC50,48h has been set at 150 mg/L.
According to Regulation (EC) N. 1272/2008 the ecotoxicological classification of similar substance 1 is 'not toxic' to Daphnia magna after an exposure period of 48 hours.
Therefore Acid Black 001 can be considered not toxic to Daphnia magna for Read Across with similar substance 1
