Key value for chemical safety assessment
Additional information
The WHO (2009) summarises the available data concerning short-term toxicity of Cr (III) compounds to aquatic invertebrates. LC50s in freshwater invertebrates ranged from 0.1 mg/l (Daphnia pulex) to 442 mg/l (Asellus aquaticus). LC50s ranging from 10 to 100 mg/l were reported for marine invertebrates. Trivalent chromium is more toxic in soft waters than hard waters.
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.
