Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
The solubility of the constituents from trichromium dicarbide is so low that they have no effect on the terrestrial toxicity. Chromium is abundant in the Earth's crust and consequently also in terrestrial and sediment environments, and therefore the contribution of anthropogenic chromium to the natural pools of chromium is not relevant either in terms of added amounts or in terms of toxicity. Based on these exposure considerations, additional sediment or soil testing is not warranted.
For comparison, the solubility of chromium (from chromium oxide in chronic T/D test) is <0.01 microg/L (Hedberg and Odnevall Wallinder 2012). The mean "bioavailable" (EDTA extractable) total chromium concentration in soil samples has been 0.053 mg/kg dry weight (WHO CICAD 76).
More information can be found in the ICDA (2010) environmental assessment, which is available upon request from the registrant.
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.
