Study design
- Total exposure duration:
- 48 h
- Post exposure observation period:
- not applicable
Test conditions
- Hardness:
- 250 mg/L expressed as CaCO3
- Test temperature:
- Blank control during the study: 19.6 - 20.4°C
- pH:
- At t=0h and t=48h
Control: 7.8 - 7.8
Test samples: 7.8 - 7.9 - Dissolved oxygen:
- At t=0h and t=48h [mg/L]
Control: 7.8 - 8.0
Test samples: 8.2 - 8.5 - Salinity:
- not applicable
- Nominal and measured concentrations:
- As the submission substance was insoluble in water (< 10µg/L), analytical verification was impossible due to sensitivity limitations. Therefore, in a limit test the nominal substance concentration of 100 mg/L in test medium was applied after filtration through a 0.45 µm membrane filter.
