Description of key information
Synthetic amorphous silica (SAS) may enter the environment either by direct emission or may be released from a product matrix. In the latter case, the route into the environment and likelihood of environmental exposure depends on the specific matrix in which SAS was originally used. The distribution will be determined not only by the intrinsic properties of SAS, but also by the environmental conditions.
Due to its physico-chemical properties, SAS is expected to mainly distribute into soil and sediment, where it undergoes natural transformation processes of weathering including dissolution and precipitation. Amorphous silica dissolution has an essential role in controlling biogeochemical cycling of silicon.
Additional information
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.
