RM-Freetext:
The average intake of silicon is 20-50 mg total Si/d
(Pennington, 1991). An estimation of 0.31 mg Si/kg bw/d in
females and 0.53 mg Si/kg bw/d in males made in an American
study, is representative for the intake in the Western
world. While the highest concentrations of total silicon are
found in seafood, eggs and diary products; the main dietary
sources are cereals and beverages.
Applicant's summary and conclusion
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.
