Any other information on results incl. tables
No auxiliary substance could help to solubilise the test substance.
Considering the low water-solubility of the test substance and in order to prevent impact of solid particles, the test substance was prepared as follows: A 1000 mg/L suspension was stirred for 2 hours; the substance in excess was then filtered. The saturated solution obtained was used as such and diluted (100% to 25%).
No immobilisation was noted at any of these concentrations.
Applicant's summary and conclusion
- Validity criteria fulfilled:
- not specified
- Conclusions:
- Due to its low water solubility, the test substance is not considered to be toxic to aquatic invertebrates under the condition of the test.
