Protoplasma 154, 25-33, 1990 - Test organisms (species):
- Daphnia magna
- Test type:
- static
- Water media type:
- freshwater
- Limit test:
- yes
- Total exposure duration:
- 48 h
- Hardness:
- about 14 ° dH (about 250 mg/L CaCO3)
- Test temperature:
- 18 - 22°C
- pH:
- ca. 7.9 +/- 0.3
- Dissolved oxygen:
- between 95.2 - 98.6 %
- Nominal and measured concentrations:
- Nominal concentration of 100 mg/L (limit test); due to the low water solubility and the fact that the study was a limit test, no further analysis was initiated.
- Details on test conditions:
- Concentration: 100 mg/L (limit test)
Static Test - Reference substance (positive control):
- yes
- Remarks:
- potassium dichromate
- Duration:
- 48 h
- Dose descriptor:
- EC50
- Effect conc.:
- > 100 mg/L
- Nominal / measured:
- nominal
- Conc. based on:
- test mat.
- Basis for effect:
- mobility
- Details on results:
- A nominal test concentration of 100 mg/L revealed no aquatic toxicity in this test system.
- Validity criteria fulfilled:
- yes
- Conclusions:
- Under the given experimental conditions, the test material showed a 24 hand 48h EC50 value > 100 mg/L nominal.
- Executive summary:
Daphnia magna exposed to a nominal concentration of 100 mg/L (limit test) for 48 hours in an open static system were not affected. The test material concentration in the aqueous medium was not quantified at the start and at the end of this study as a very low water solubility was calculated for this test item (ca. 0.059 µg/L). Therefore, the development of an analytical method with a sufficiently low detection and quantification limit would be very time and cost intensive. Due to the absence of any adverse effects at the saturation concentration, the study was performed without analytical concentration verification. For the test material, the following EC50 values for Daphnia magna were determined: 24h-EC50: > 100 mg/L nominal, 48h-EC50: > 100 mg/L nominal.
- Endpoint:
- short-term toxicity to aquatic invertebrates
- Type of information:
- read-across from supporting substance (structural analogue or surrogate)
- Adequacy of study:
- key study
- Justification for type of information:
- For this endpoint information from structural similar compounds is available. The studies for these similar compounds were performed according to GLP and the methods applied are fully compliant with OECD TG 202. See chapter 13 report for a more detailed justification.
- Reason / purpose for cross-reference:
- read-across source
- Duration:
- 48 h
- Dose descriptor:
- EC50
- Effect conc.:
- > 100 mg/L
- Nominal / measured:
- nominal
- Conc. based on:
- test mat.
- Basis for effect:
- mobility
- Remarks on result:
