Description of key information
The substance is inorganic, not biodegradable metal.
Key value for chemical safety assessment
Additional information
Waiving of the need for data for this environmental end point is considered relevant because “The substance is highly insoluble in water” (ECHA 2008, Chapter R 7B – Endpoint Specific Guidance). The dissolution of the chromium metal is so low (0.005 µg/L) that its contribution to the environmental background level is negligible.
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.
