Materials and methods

Test guideline
Qualifier:
no guideline followed
Guideline:
other: The saturated solution of the test compound was determined in the short-term toxicity to aquatic inverterbrate as the test compound is poorly soluble. The concentration of the saturated solution has been measured by gas chromatography.
Deviations:
not applicable
Principles of method if other than guideline:
Satured solution (100 mg of dibromo-1,6-hexane with 1 liter of test medium, for 24 hours at 20 ° C) has been prepared. Then % of this saturated salution have been used to exposed Daphnia magna in a short -term toxicity test. The concentrations used during the test have been followed by gas chromatography.

Results and discussion

Water solubility
Water solubility:
37.5 mg/L

Applicant's summary and conclusion

Conclusions:
Interpretation of results (migrated information): slightly soluble (0.1-100 mg/L)
The maximum solubility of the test substance is 37.5 mg/L. This value has been measured by gas chromatography after agitation of 100 mg of dibromo-1,6-hexane with 1 liter of test medium, for 24 hours at 20 ° C.
