- PREPARATION AND APPLICATION OF TEST SOLUTION (especially for difficult test substances)
- Method: Water Accommodated Fractions (WAFs) were prepared by stirring various amounts of the test item distillates (coal tar), heavy oils (AOH, anthracene oil with BaP ≥ 50 ppm) in dechlorinated tap water for 24 h with magnetic stirrers. The WAFs were prepared in 20-L glass fish tanks. These were equipped with a glass tube that allowed the separation of the water phase by siphoning.
The test loadings of AOH were weighed on watch-glasses, that afterwards were placed into the glass vessels. The glass tanks were then filled with the tap water. 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 extracts gained with this method were clear.

- Details on results:
- Observations during the test:
- No mortality
- Control: Swarming behaviour and activity were normal.
- 100 mg/L: Activity was slightly reduced, and surfacing could be observed at the start of the observation periods 0 – 24 h, 24 – 48 h, 48 – 72 h and 72 – 96 h. These sublethal effects could not be observed at the end of the observation periods 0 – 24 h, 24 – 48 h and 48 – 72 h. However slightly reduced activity could also be observed at the end of the observation period 72 – 96 h.
Observations at the end of the test after feeding of the fish:
- Control: All fish fed immediately.
- 100 mg/L: All fish fed with slight retardation compared to the control.
After the end of the test, the fish were kept in de-chlorinated tap water from 20.12.08 to 23.12.08.
During this period, fish derived from the control and the test loading rate of 100 mg/L showed normal behaviour.

Applicant's summary and conclusion
- Validity criteria fulfilled:
- yes
- Remarks:
- - Dissolved oxygen in all vessels: ≥ 81 % (limit value > 60 %) - Lethality in the control: 0 fish (limit value ≤ 1 fish)
- Conclusions:
- Due to the nature of the test substance (UVCB), the fraction dissolved in water (WAF) is different for different loadings (nominal concentrations). Therefore, aqueous toxicity was determined based on loadings.
In an acute (96 h), semi-static fish toxicity test with the test substance distillates (coal tar), heavy oils (AOH, anthracene oil with ≥ 50 ppm BaP), only one concentration (100 mg/L) was tested (limit test). No mortality was observed in the test. Thus, the LL0 is 100 mg/L and the LL50 is greater than 100 mg/L.
