- Details on test solutions:
- Preparation of test solutions started with a solution of 100 (combined limit/range-finding test) or 220 mg/l (final test) applying 15 minutes of magnetic stirring to accelerate the dissolving of the test substance in the test medium. The lower test concentrations (0.1, 1.0 and 10 mg/l in combined limit/range-finding test; 10, 22, 46 and 100 mg/l in final test) were prepared by subsequent dilutions of the 100 or 220 mg/l solution in test medium. The final test solutions were all clear and colourless.
Controls: Test medium without test substance or other additives - Test organisms (species):
- Daphnia magna
- Details on test organisms:

- Salinity:

- Nominal and measured concentrations:
- Only samples taken from the two highest test concentrations and the control were analysed, based on the biological results. Analysis of the samples taken at the start of the test showed measured concentrations of 88 and 213 mg/l at the nominal concentrations of 100 and 220 mg/l, respectively. During the exposure period these measured concentrations remained constant (i.e. 89-91% of initial). Based on these results, the nominal concentrations were used to calculate the effect parameters.

- Conc. based on:
- test mat.
- Basis for effect:
- mortality
- Details on results:
- Combined limit/range finding test:
After 48 hours of exposure 60% immobility was observed at 100 mg/l. No significant immobility was observed at any of the lower test concentrations during the test period. Therefore, the expected EC50 was just above nominal 100 mg/l.
Immobility at 48h: 10% at 0.1 mg/l; 0% at 1.0 mg/l; 10% at 10 mg/l; 60% at 100 mg/l.
Final test:
No significant immobility was observed at any of the test concentrations during the test period. Therefore, the responses recorded at nominal 100 mg/l were not in agreement with the results of the combined limit/range-finding test. However, the responses recorded in this final test allowed for reliable determination of an EC50 because the results at 220 mg/l supported the results at 100 mg/l.
Immobility at 48h: 0% at 10 mg/l; 5% at 22 mg/l; 0% at 46 mg/l; 5% at 100 and 220 mg/l. - Results with reference substance (positive control):
- - Results with reference substance valid? Yes
- Mortality at 48h: 0% at 0.10 mg/l; 5% at 0.18 mg/l; 50% at 0.32 mg/l; 85% at 0.56 mg/l; 100% at 1.0 and 1.8 mg/l
- EC50/LC50: 48h-EC50 was 0.34 mg/l with a 95% confidence interval between 0.28 and 0.40 mg/l. - Validity criteria fulfilled:
- yes
- Conclusions:
- Under the conditions of the present study Ditetrahydrofurylpropane did not induce significant acute immobilisation of Daphnia magna at 220 mg/l after 48 hours of exposure (NOEC).
The 48h-EC50 was beyond 220 mg/l based on analytically confirmed nominal concentrations.
