Description of key information
The rate and extent to which chromium (III) oxide produces soluble (bio)available ionic and other chromium-bearing species in environmental media is limited. Further, the poor solubility of chromium (III) oxide is expected to determine its behaviour and fate in the environment, including its potential for bioaccumulation. Proprietary studies are not available for chromium (III) oxide. However, the fate of chromium (III) oxide in the environment is evaluated by assessing the fate of its ecotoxicologically relevant moiety, the chromium (III) ion, and read-across to data available for other chromium (III) substances is applied.
The available BAFs for chromium (III) indicate a low potential for bioaccumulation in aquatic and terrestrial environments. For chromium, as essential element, it is expected that internal chromium levels are homeostatically regulated by all living organisms. Chromium is not expected to biomagnify in aquatic or terrestrial food-chains.
Thus, the potential for bioaccumulation of chromium (III) oxide in aquatic and terrestrial environments is low based on its poor solubility in environmental media and the low bioaccumulation factors reported for chromium.
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.
