Description of key information
Nanomaterials do not reach the equilibrium in adsorption-desorption studies with soils.
Key value for chemical safety assessment
Additional information
Adsorption and desorption are not applicable because silicon dioxide/silicate and aluminum are two of the most abundant materials in the Earth´s surface. Whatever their origin, once released into the environment, no distinction can be made to natural silicates (see also IARC monographs on the evaluation of the carcinogenic risk of chemicals to humans. Silica and some silicates, International Agency for Research on Cancer, Lyon, 81-143, World Health Organization, Vol. 42 1987) or aluminates.
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.
