- Vehicle:
- no
- Details on test solutions:
- PREPARATION AND APPLICATION OF TEST SOLUTION (especially for difficult test substances)
- Method: Water Accommodated Fractions (WAFs) prepared by stirring various amounts of the test item in Daphnia-medium
for 24 h with magnetic stirrers. The WAFs were prepared in closed glass beakers.
The beakers were equipped with a glass tube that allowed the separation of the water phase by siphoning.
The test loadings of anthracene oil were weighed on weighing scoops, that afterwards were placed into the glass beakers.
The beakers were then filled with Daphnia-medium.
Mixing was carried out at a speed that was slow enough not to cause dispersion or emulsification of the undissolved fraction
of the test item. To ensure this, the vortex developed at the surface by stirring was set at ~ 10 % of the water depth.
After stirring for 24 h, the WAFs were allowed to stand for 1 h before use to facilitate phase separation.
The test vessels were closed immediately following transfer of the WAFs.
