Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
No NOEC available
Key value for chemical safety assessment
Additional information
Daphnia magna and Leuciscus idus were found to be the most sensitive species both revealing LC50 values >146 mg/L. Silica is found in European rivers in mean concentrations of 7.5 mg SiO2/L (Jorgensen et al. 1991). Therefore, the NOEC for fish in chronic toxicity tests is expected to be comparable to the NOEC for Daphnia and Leuciscus in the short-term tests. Further testing is not appropriate and should be avoided due to animal welfare.
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.
