Description of key information
Acutely harmful to aquatic invertebrates.
Key value for chemical safety assessment
Additional information
Considering the acute toxicity of butyl vinyl ether (CAS 111-34-2) to aquatic invertebrates, experimental data are available from a GLP compliant study conducted according to OECD TG 202 using D. magna as test organism. In this limit test, the 48-h EC50 was determined to be >27.9 mg/L, based on measured test concentrations (geomean), representing the maximum solubility that could be achieved under the test conditions. However, considering the substance’s measured water solubility of 460 mg/L (BASF SE, 2014; see IUCLID chapter 4.8), the substance is concluded to be harmful to aquatic invertebrates from a precautionary point of view.
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.
