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.
