Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Description of key information
The insolubility of trichromium dicarbide and the ubiquitous presence of chromium in the environment make its ecotoxicity very unlikely and also the testing of the environmental degradation and ecotoxicity mainly scientifically unjustified. The lack of endpoint data from trichromium dicarbide does not allow the derivation of PNECs.
Key value for chemical safety assessment
Additional information
The insolubility of trichromium dicarbide and the ubiquitous presence of chromium in the environment make its ecotoxicity very unlikely and also the testing of the environmental degradation and ecotoxicity mainly scientifically unjustified. The lack of endpoint data from trichromium does not allow the derivation of PNECs.
For information and for comparison, the PNECs for trivalent chromium have been determined in the ICDA (2010) environmental report. The report includes detailed description of the rationale behind the derivation PNECs.
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.
