Description of key information
Additional information
In accordance with column 2 of REACH Annex VII, studies on biodegradation are not applicable for inorganic substances. Biodegradation in water, sediment or soil is not applicable as environmental fate process for silicic acid, lithium salt.
Furthermore, silica is continuously removed from water by biochemical processes: diatoms, radiolarians, silicoflagellates, and certain sponges serve as a sink for silicon by incorporating it into their shells and skeletons as amorphous biogenic silica, frequently referred to as opal (SiO2· nH2O). They can deplete dissolved silica in surface waters to less than 1 mg/L during blooms (Edwards 1973).
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.
