Description of key information
Additional information
Due to the hydrolysable nature of disodium hexafluorosilicate, bioaccumulation cannot be assessed.
The accumulation and metabolism behaviour of the main species present in aqueous solutions have been reviewed in the Environmental Health Criteria (IPCS/WHO, 1994 and IPCS/WHO, 2002). Inorganic fluorides tend to accumulate preferentially in the skeletal and dental hard tissues of vertebrates, exoskeletons of invertebrates and cell walls of plants (Hemens & Warwick, 1972; Davison, 1983; Michel et al., 1984; Kierdorf et al., 1997; Sands et al., 1998). In addition, accumulation of fluoride is considered in the risk assessment of HF (EU, 2001).
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.
