The 48-hour EC50 for hexyl acetate was found to be 9.1 mg/l and the NOEC 0.84 mg/l.
A 48-hour OECD 202 study was conducted to determine the acute toxicity
of hexyl acetate to Daphnia magna.
Following a range-finding test, Daphnia magna were exposed to the
test substance at initial measured concentrations of 1.0, 1.8, 3.2, 5.6,
14, 25, 45, 78 and 141 mg/l for 48 hours. Conditions were semi-static
and the test media were changed after 24 hours. Test temperature was 21
Observations for immobilization or any adverse effects were made at 24
and 48 hours after test initiation. Dissolved oxygen and pH were
measured at the start and termination of the test. Water temperature was
The 48-hour EC50 was found to be 9.1 mg/l, and the NOEC was determined
to be 0.84 mg/l based on time-weighted mean concentrations.
