Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Endpoint summary
Administrative data
Description of key information
Data on the aquatic or terrestrial bioaccumulation of sodium dichromate are not available. The substance sodium dichromate consists of sodium cations and dichromate anions (Cr2O7(2 -)). Based on the solubility of sodium dichromate in water, read-across to data available for other (soluble) chromate substances is applied. Please refer to the respective endpoint summaries for further information.
Data on soluble chromium(VI) substances
Based on a weight of evidence approach using data on aquatic bioaccumulation in fish, crustacea and aquatic plants, a low potential for bioaccumulation is observed for chromium (VI). A similar conclusion was made in the EU RAR (ECB, 2005), i.e. the bioaccumulation factor for chromium (VI) in fish is relatively low at around 1 L/kg. Further, the potential for terrestrial bioaccumulation seems to be low based on a non-reliable study with Lolium perenne (ryegrass) and a soluble Cr(VI) substance that reports BSAF values of ≤ 0.004 for shoots and roots (Otabbong, 1990; Klimisch 3).
Additional information
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.
