Additional information
As an inorganic substance, yttrium oxide is not biodegradable. Based on the analogy made with comparable salts of yttrium, yttrium carbonate and yttrium chloride should not show any potential for bioaccumulation.
According to all the available data, yttrium oxide does not require any classification for the environmental part under the 1272/2008/EC regulation, on the basis on the absence of adverse effect at the limit of solubility and the absence of bioaccumulation potential.
Conclusion on classification
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.
