Additional information

The toxicity of ethyl vinyl ether to Leuciscus idus was tested in a study accomplished in accordance with German Standard DIN 38412, part L15. A LC50 of 3158 mg/l was detected after 96 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 a LC50 (96 h) of 1636 mg/L.

For a more conservative approach the key information on toxicity of the substance to fish 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 a closed semistatic test system set up according to OECD guideline 203 zebra fish were exposed to isobutylether for 96 hours. At test termination a LC50 of 28.3 mg/l was determined (BASF AG, 2004).
