EC number: 911-926-8 | CAS number: -
Short-term toxicity to aquatic invertebrates
Administrative data
Link to relevant study record(s)
- 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 available

Description of key information
Exposure of Daphnia magna to the test item resulted in significant mortalities at the test concentration of 1.5 mg/L resulting in 100% mortalities by Day 5.
The 21-Day EC50 (immobilization) value, based geometric mean measured concentrations, for the parental daphnia generation (P1) was calculated to be 1.0 mg/L. Due to the nature of the data, no confidence limits could be determined.
The 21-Day EC50 (reproduction) based on geometric mean measured concentrations was 0.56 mg/L. Due to the nature of the data, no confidence limits could be determined.
The "Lowest Observed Effect Concentration" (LOEC) and the "No Observed Effect Concentration" (NOEC) based on geometric mean measured concentrations were 0.52 and 0.15 mg/L respectively.
The Chronic Value (ChV) was determined to be 0.28 mg/L.

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.
