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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Additional information
Terrestrial studies with earthworm, plants and microorganisms are available for the structural related fly ash. The chemical components of cenospheres are in the same range as for fly ash. This result is expected since cenospheres are a component of fly ash and the results of fly ash can be used as read across for ash (residues), cenospheres. The test substance shows only low toxicity at high test concentrations.
As the test substance is not classified as toxic or harmful, the substance is not considered to cause toxic effects in predators. Additionally, the bioaccumulation potential is low and thus the test substance is considered to cause low hazard to predators. Thus, a study with birds is not needed due to animal welfare reasons.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.
