- experimental study
- Adequacy of study:
- key study
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 202 (Daphnia sp. Acute Immobilisation Test)
- Deviations:
- no
- Qualifier:
- according to guideline

- Conclusions:
- Investigation of short-term toxicity to Daphnia magna is ongoing and relevant publicly available data are not available. PNECs required for risk assessment are therefore based on current company prediction (LC50 0.032 mg/L).
- Executive summary:
Investigation of short-term toxicity to Daphnia magna is ongoing and relevant publicly available data are not available. PNECs required for risk assessment are therefore based on current company prediction (LC50 0.032 mg/L).
