Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Short-term toxicity to aquatic invertebrates
Administrative data

Description of key information
The 48-h EC50 value is 9.2 mg/L in aquatic invertebrates (Daphnia magna).
Key value for chemical safety assessment
Additional information
The acute toxicity to aquatic invertebrates was determined in a study, where daphnids (D. magna, 30 per concentration) were exposed to nominal concentrations of 0 (control), 1, 2, 5, 10, 20, 50, 100, 200, 500 and 1000 mg/L for 48 hours under static conditions. Test concentrations were not analytically confirmed. Immobilization was determined after 24 and 48 hours of exposure. All daphnids were immobile in the two highest concentrations after 24 hours and immobile in the three highest concentrations after 48 hours. Overall, the test concentrations showed concentration-dependent effects on the mobility of the daphnids. Based on these results, the 48-h EC50 value was determined at 9.2 mg/L.
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.
