Short-term toxicity to aquatic invertebrates
Administrative data
Link to relevant study record(s)
Description of key information
The maximum achievable test concentration was 75 mg/l, which is consistent with the measured water solubility of the test material at 73 mg/l. The substance was not found to be toxic at the maximum tested concentration. The EC50 was reported as >75 mg/l.
Key value for chemical safety assessment
Fresh water invertebrates

Additional information
A study was conducted on the registered substance to determine the acute toxicity of the substance to aquatic invertebrates. The potential for the substance to be acutely toxic to aquatic invertebrates was determined in accordance with the OECD Guideline for Testing of Chemicals 202. The species used in the test was Daphnia magna. Based on the results of preliminary testing conducted at Smithers Viscient, Shawbury and consultation with the Study Sponsor, nominal concentrations of 4.7, 9.4, 18.8, 37.5 and 75 mg/l were selected for the definitive exposure. The maximum achievable test concentration was 75 mg/l, which is consistent with the measured water solubility of the test material at 73 mg/l. The 24 and 48 hour NOEC for immobility was >1 mg/l. No adverse effects of the test substance were observed in the Daphnia magna exposed to any treatment levels at 48 hours. The substance was not found to be toxic at the maximum tested concentration.
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.
