Additional information
In accordance with the ECHA Guidance R.10 (May 2008), the derivation of PNECs is required for the chemical safety assessment (CSA) of substances manufactured/imported/used in quantities from 10 t/a onwards. Thus, no PNECs have been derived for the REACH registration of Chromium diboride in the tonnage band 1-10 t/a (REACH Annex VII).
Conclusion on classification
Studies investigating the acute toxicity of Chromium diboride to aquatic invertebrates and algae do not have to be conducted as the substance is highly insoluble in water, hence aquatic toxicity is unlikely to occur. Thus, a classification for aquatic environmental hazards is not warranted.
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.
