Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Additional information
Aquatic toxicity is unlikely at the level of solubility of trichromium dicarbide. According to column 2 of REACH Annex VIII, the study is not needed for highly insoluble substances.
For comparison, however, toxicity data obtained with mainly trivalent chromium compounds has been presented in various endpoints. This is only for informational purposes to clarify that the toxic concentrations are much higher than the concentrations arising in the environmental conditions from trichromium dicarbide. The solubility of chromium (from chromium oxide in chronic T/D test) is ca. 0.005 microg/L, and the toxic concentrations typically of the order of milligrams/litre.
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.
