With high probability ethyl vinyl ether is acutely harmful to fish.
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).
