The LC50 of hexyl acetate to fish was determined to be 4.4 mg/L.
Two public studies are available for acute toxicity of hexyl acetate to
fish. A weight of evidence approach is taken in order to determine the
acute toxicity to fish. Studies are outlined briefly below:
A study was carried out to compare values derived from a quantitative
structure-activity relationships (QSAR) method with experimental
results. The experimental results used in this study were taken from
COMPUTOX (1995) toxicity database. The 96-hour logLD50 for hexyl acetate
was found to be -1.52 mmol/l. This equates to a 96 -hour LD50 of 4.4
A 96 hour acute toxicity study was carried out to determine the LC50 of
n-hexyl acetate on fathead minnow. The test was conducted using a
flow-through system. Twenty-five fish that were 30 days old were exposed
to the test substance in water at a temperature of 25oC. Mortality was
checked and recorded at 1, 3, 6, 12, 24, 48, 72, and 96 hours after test
initiation. The 96-hour median lethal concentration was found to be 4.4
mg/l based on the results of this study.
