Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Description of key information
The lowest 48-hour EC50 value for Daphnia magna was determined to be 0.33 mg/L
Key value for chemical safety assessment
Fresh water invertebrates

Additional information
An acute Daphnia test was conducted and based on measured dissolved aluminium concentrations the lowest 48 -hour EC50 value was 0.33 mg/L.
The lowest 48-hour LC50 from three acute Daphnia tests was 323 mg/L NO3-N. This equates to an LC50 for nitrate of 1430 mg/L NO3.
The aluminium ion was determined to be the most toxic when compared to nitrate and therefore endpoints based on aluminium will be used.
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.
