- not reported
- Test temperature:
- Temp:20-23°C
- pH:
- 7.5-8.3
- Dissolved oxygen:
- 7.2-8.7 mg/L
- Salinity:
- not reported
- Nominal and measured concentrations:

- Details on test conditions:
- 65 hours before start of study 10 fish/concentration were placed in the test container (20l).
At test start he test substance was weighted in a flask, diluted with water and homogenised by ultra turrax. The solution was transferred to the test container under continouous stirring and pH, O2 and temperature are recorded.
Through the course of the study the behavior of the fish was observed repeatedly.
Dead fish were removed and examined macroscopical. - Reference substance (positive control):

In the concentrations of 100 mg/L and 500 mg/L changes in behavior could be observed.
In the concentrations of 1 mg/L and 10 mg/L there was no difference in the behavior to the control.
