The acute toxicity of the test item on
Daphnia magna over an exposure period of 48 hours in a static system was
assessed according to OECD Guideline 202 and EU method C.2. Due to the
test items poor water solubility (maximum water solubility determined to
be 0.08 mg/L), a supersaturated solution was prepared thereby simulating
worst-case scenario conditions with this 48-hour acute toxicity test
with Daphnia magna. Based upon the results of the preliminary
range-finding test, nominal concentrations of 35.0, 45.5, 59.2, 76.9 and
100.0 % v/v saturated solution were investigated in the main study.
Under these conditions all analytical
determined test concentrations were below the limits of quantification
when sampled at the start and at the end of the experiment. Therefore,
all biological results are related to loading rate and % of saturated
The NOEC was determined to be 1000 mg/L
(loading rate) and the LOEC, EC100 and the EC50 values were determined
to be higher than 1000 mg/L (loading rate).
For the acute toxicity on Daphnia magna
conducted with the test item over an exposure period of 48 hours, the
NOEC was determined to be 1000 mg/L (loading rate) and the LOEC, EC100
and the EC50 values were determined to be higher than 1000 mg/L (loading
