Acute tests on all three trophic levels were performed to examine
the aquatic toxicity of isobutyl vinyl ether. Fish turned out to be the
most sensitive species revealing a LC50 (96h) of 28.3 mg/L. Effects
towards invertebrates and daphnia were found in the same range providing
an ErC50 (72h) of 45.9 mg/L and an EC50 (48h) of 52 mg/L, respectively.
Thus, isobutyl vinyl ether is considered acutely harmful for aquatic
