Short-term toxicity to aquatic invertebrates
Administrative data
Link to relevant study record(s)
- Endpoint:
- short-term toxicity to aquatic invertebrates
- Type of information:
- experimental study
- Adequacy of study:
- supporting study
- Study period:
- February 07, 2013 - February 17, 2014
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Reason / purpose for cross-reference:
- reference to other study
- Qualifier:
- equivalent or similar to guideline
- Guideline:
- OECD Guideline 202 (Daphnia sp. Acute Immobilisation Test)
- Version / remarks:
- Range finding study of OECD Guideline 211
- GLP compliance:
- no
- Analytical monitoring:
- no
- Test organisms (species):
- Daphnia magna
- Test type:
- static
- Water media type:
- freshwater
- Limit test:
- yes
- Total exposure duration:
- 48 h
- Nominal and measured concentrations:
- 100 mg/L (nominal)
- Key result
- Duration:
- 48 h
- Dose descriptor:
- EC50
- Effect conc.:
- > 100 mg/L
- Nominal / measured:
- nominal
- Conc. based on:
- test mat.
- Basis for effect:
- mobility
- Validity criteria fulfilled:
- not applicable
- Conclusions:
- A non GLP preliminary range finding test was carried out as acute immobilisation test to Daphnia magna STRAUS. No immobilisation was observed after 24 h and 48 h at a nominal loading rate of 100 mg/L. The 48-h EC50 was determined to be greater than 100 mg/L.
- Endpoint:
- short-term toxicity to aquatic invertebrates
- Data waiving:
- study scientifically not necessary / other information available
- Justification for data waiving:
- the study does not need to be conducted because a long-term aquatic toxicity study on invertebrates is proposed to be conducted

Description of key information
According to Annex VII of REACH Regulation, the study does not need to be conducted because a long-term study on Daphnia magna is available.
However, a non GLP preliminary range finding test is available as acute immobilisation test to Daphnia magna STRAUS. No immobilisation was observed after 24 h and 48 h at a nominal loading rate of 100 mg/L. The 48-h EC50 was determined to be greater than 100 mg/L (nominal).

Additional information
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). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
