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.
