EC number: 218-620-7
CAS number: 2206-94-2
Short-term toxicity to aquatic invertebrates: 48-h EC50 24 mg/l and NOEC 9.3 mg/l (measured, geometric mean concentration), OECD 202
A 48 hour EC50 value of 24 mg/l
and NOEC value of 9.3 mg/l, based on measured geometric mean
concentrations, have been reported for the effects of α-methylenebenzyl
acetate on mobility of Daphnia magna.
During validation of the analytical
method the test item was stable under the test conditions without test
Considerable loss of test material was
experienced during the test with the Daphnia present.
At the beginning and at the end of the
test, the content of the test item in the test solutions was determined
chromatography. The measured concentrations were in the range 97
- 100 % of the nominal concentration at the start of the test. At the
end of the test the measured concentrations were only in the range 0 -
14 % of the nominal concentrations.
Therefore determination of the biological
results was based on the geometric mean of the measured concentrations.
