Long-term toxicity to aquatic invertebrates
Administrative data
- Endpoint:
- long-term toxicity to aquatic invertebrates
- Data waiving:
- study scientifically not necessary / other information available
- Justification for data waiving:
- other:
- Justification for type of information:
- This information was requested based on ECHA decision number CCH-D-2114453719-37-01/F, but due to notified reduced tonnage to Annex VIII, this endpoint is not required. However, this dossier has not been possible to submit at Annex VIII do to business rules and restrictions within the REACH IT system. Requests have been made to rectify the tonnage reduction notification.
Other Joint Registrants are not relying on Annex IX data.
Cross-reference
- Reason / purpose for cross-reference:
- data waiving: supporting information
Reference
- Endpoint:
- toxicity to aquatic algae and cyanobacteria
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 72 hours, performed 2020
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 201 (Alga, Growth Inhibition Test)
- Version / remarks:
- Including analytical verification
- GLP compliance:
- yes (incl. QA statement)
- Specific details on test material used for the study:
- Purity: 90.8 % Non-volatiles at 130 °C
Physical State/Appearance: Viscous brown liquid - Analytical monitoring:
- yes
- Details on sampling:
- Analysis of the test preparations at 0 hours showed measured test concentrations to range from 0.0012 to 0.37 mg/L. Analysis of the test preparations at 72 hours showed measured test concentrations to range from 0.00074 to 0.29 mg/L.
Given this decline in measured test concentrations it was considered justifiable to base the results on the geometric mean measured test concentrations in order to give a "worst case". - Vehicle:
- no
- Details on test solutions:
- 0Nominal concentrations of 0.0010, 0.0032, 0.010, 0.032, 0.10 and 0.32 mg/L
(three replicate flasks per concentration) - Test organisms (species):
- other: Raphidocelis subcapitata
- Test type:
- static
- Water media type:
- freshwater
- Limit test:
- no
- Total exposure duration:
- 72 h
- Hardness:
- Not specified, but stated to be to OECD standard test media
- Test temperature:
- Temperature was maintained at 24 ±1 ºC throughout the test
- pH:
- The pH value of the control cultures was observed to increase from pH 7.7 at 0 hours to pH 9.0 at 72 hours.
- Nominal and measured concentrations:
- Nominal concentrations of 0.0010, 0.0032, 0.010, 0.032, 0.10 and 0.32 mg/L
Mean measured test concentrations 0.00093, 0.0030, 0.010, 0.033, 0.11 and 0.33 mg/L. - Reference substance (positive control):
