- PREPARATION AND APPLICATION OF TEST SOLUTION
The standard test procedures required generation of test solutions, which should contain completely dissolved test substance concentrations or stable and homogeneous mixtures or dispersions. The testing of concentrations that disturb the test system should be prevented (e.g. film of the test substance on the water surface).
The batch of Setafix X 11342 tested was a white/yellow crystal solid with a purity of >95% and not completely soluble in test medium at the concentrations tested.
A pre-test was performed to examine the solubility of the test substance in the test medium. A weighed amount of 10 mg was added to 1000 ml test medium. Magnetic stirring or ultra sonication did not accelerate 1the dissolving or dispersing of the test substance. Subsequently, acetone was used as a pre-solvent, but the substance did not dissolve in pure acetone at a concentration of 100 mg/ml.
In the limit test, a stock was prepared at 100 mg/I applying 72 hours of magnetic stirring. The resulting solution was clear and contained precipitate and a floating layer. After filtration (ca. 5 μm), the resulting test solution was clear and colourless. - Test organisms (species):

- Start of each batch: With newborn daphnids, i.e. less than 3 days old, by placing about 250 of them into 5 litres of medium in an all-glass culture vessel.

EFFECT PARAMETERS MEASURED (with observation intervals if applicable) :
Effect parameters based on the average exposure concentration in a filtrate prepared at a loading rate of 100 mg/I are as follows:
Observed NOEC = < 0.038 (Concentration of Setafix X 11342 in mg/l)
24h-EC50 = < 0.038 (Concentration of Setafix X 11342 in mg/l)
48h-EC50 = < 0.038 (Concentration of Setafix X 11342 in mg/l)
TEST CONCENTRATIONS:
- Daphnia magna exposed to a filtrate prepared at a loading rate of 100 mg/I during the 48-hour test period.
- Analysis of the samples taken during the limit test showed that the mean measured concentration in the samples taken from the filtrate at the start of the test was 0.077 mg/I. During the exposure period the measured concentration had decreased to 0.019 mg/I (24 % of initial). Thus, the actual concentration was maintained above the water solubility, which was 8.8 μg/l (NOTOX Project 330918). - Reference substance (positive control):

- Details on results:
- - Measured concentrations:
Analysis of the samples taken during the limit test showed that the mean measured concentration in the samples taken from the filtrate at the start of the test was 0.077 mg/I. During the exposure period the measured concentration had decreased to 0.019 mg/I (24 % of initial). Thus, the actual concentration was maintained above the water solubility, which was 8.8 μg/l (NOTOX Project 330918).
Based on the analytical results, the calculated average exposure corwentration was 0.038 mg/I
- Effect parameters based on the average exposure concentration in a filtrate prepared at a loading rate of 100 mg/I are as follows:
Observed NOEC = < 0.038 (Concentration of Setafix X 11342 in mg/l)
24h-EC50 = < 0.038 (Concentration of Setafix X 11342 in mg/l)
48h-EC50 = < 0.038 (Concentration of Setafix X 11342 in mg/l)
- Any observations (e.g. precipitation) that might cause a difference between measured and nominal values:
No undissolved material was observed during the test
- Effect concentrations exceeding solubility of substance in test medium:
No EC50 could be calculated because the test substance proved to be non-toxic (EC50 > maximum soluble concentration). - Results with reference substance (positive control):
- - Results with reference substance valid? Yes
The actual responses in this reference test with K2Cr20 7 are within the ranges of the expected responses at the different concentrations. Hence, the sensitivity of this batch of D. magna was in agreement with the historical data collected at NOTOX.
-The 24h-EC50 was 0.97 mg/I with a 95% confidence interval between 0.86 and 1.2 mg/I
- The 48h-EC50 was 0.66 mg/I with a 95% confidence interval between 0.57 and 0.83 mg/I - Validity criteria fulfilled:
- yes
- Remarks:
- The study met the acceptability criteria prescribed by the protocol
- Conclusions:
- Under the conditions of the present study Setafix X 11342 did not induce more than 25% immobilisation of Daphnia magna exposed to a filtrate prepared at a loading rate of 100 mg/I during the 48-hour test period. The average exposure concentration was 0.038 mg/I, which was above water solubility. Hence, the 48h-EC50 for Daphnia magna exposed to Setafix X 11342 was above the water solubility limit of 8.8 μg/I.

The batch of Setafix X 11342 tested was a white/yellow crystal solid with a purity of >95% and not completely soluble in test medium at the concentrations tested.
A limit test was performed exposing 20 daphnia in quadruplicate (5 per vessel) to a filtered solution prepared at a loading rate of 100 mg/l and a blank-control. The test solution was magnetically stirred for 72 hours, after which it was filtered over a paper filter (ca. 5 μm). The filtrate was clear and colourless. The total test period was 48 hours. Samples for analysis were taken at the start and the end of the test.
Analysis of the samples taken during the limit test showed that the mean measured concentration in the samples taken from the filtrate at the start of the test was 0.077 mg/l. During the exposure period the measured concentration had decreased to 0.019 mg/l (24 % of initial).
