Description of key information

With high probability the substance is acutely harmful to Daphnia magna. 

Key value for chemical safety assessment

Additional information

The toxicity of ethyl vinyl ether to Daphnia magna was tested in a study accomplished in accordance with Directive 79/831/EEC, Annex V, Part C. An EC50 of > 100 mg/l was detected after 48 hours, however the study was not performed in a closed system and the substance may have evaporated from the test solutions (BASF AG, 1988). A recalculation of the test item concentration based on a stability study originally conducted for the data derived from a study on Daphnia resulted in an EC50 (48 h) of > 51.8 mg/L.

For a more conservative approach the key information on toxicity of the substance to Daphnia is derived from isobutyl vinyl ether, which is a structural analogue to ethyl vinyl ether, according to SIDS Initial Assessment Profile 23, 17-20 October 2006. In sealed exposure vessels set up according to OECD guideline 202 daphnids were exposed to isobutyl vinyl ether for 48 hours. At test termination an EC50 of 46.3 mg/l was determined (BASF AG, 2004).
